Explain and describe what a limiting factor is

Explain and describe what a limiting factor is Limiting factor is any factor that restricts a company or an organisations activities. In simple words, a limiting factor is the factor which is limited or not freely available to the company. Limiting factors in an organisation can be labour time, raw material, machine hours or space. For example, when sales demand excess the productivity capacity, the company do not have enough resources to produce the product, the scarce resource will be the factor that restricts the companys activities. The production constraints can be removing and additional resources can be acquired when the scarce resources are existed. Hence, the scarce resources should be identified to make sure the company has enough resources to produce their products as many as their wish. By using limiting factor, we can maximize the profit when obtained the greatest possible contribution to profit each time. Example1: A B C Contribution per unit of output RM 24 RM 20 RM 12 Machine hours required per unit of output 6 hours 2 hours 1 hours Estimated sales demand 3,000 units 3,000 units 3,000 units Required machine hours 18,000 hours 6,000 hours 3,000 hours The machine hour is limited to 18,000 hours for the period because of the breakdown of one machine. Consider Example 1. From the example 1, we know that the company required total 27,000 machine hours to produce the total sales demand of the product A, B and C that they estimated. However, the company only has 18,000 machine hours for the period because of the breakdown of one machine. In this situation, companys activities are limited in the available of machine hours. When we looking at the available information, we will think that the company should produce the product A first since the contribution per profit for product A is the highest but this assumption can be wrong. This is because produce a product A required 6 machine hours, whereas product B required 2 machine hours and product C required 1 machine hours only. The company can concentrates on producing 3,000 units of product B and C respectively and still have machine hours left to produce product A. In other words, if the company only concentrates on produce the product A, there will no machine hours left to the company to produce B and C. In order to maximize the companys profit, we should use limiting factor to calculate the greatest possible contribution per profit for each product and rank profitability of the product to obtain the optimum production plan. (b) Explain the techniques that have been developed to assist in business decision- making when single or multiple limiting factors are encountered (16 marks) Single limiting factor- Limiting factor analysis When single limiting factor are encountered, we have to use limiting factor analysis to help companies to identify the scarce resources and maximize profit by using the best combination of available resource. In limiting factor analysis, we should identify the bottleneck resources first. Secondly, we should calculate the contribution per unit for each product. Next, we should calculate the contribution per unit of the bottleneck resource for each product. After we get the contribution per unit of bottleneck resource, we can rank the products of the contribution per unit of bottleneck resource. Finally, we can allocate the resources from the highest contribution per profit to the lowest contribution per profit by the ranking. By doing so, we can obtained the greatest possible profit when resources are limited by single limiting factor. Example 2: X Y Machine hours per units 3 hours 4 hours Sales demand 2,000 units 3000 units RM RM Selling price 32 50 Less : Direct Material 10 20 Direct Labour 5 8 Variable Overhead 5 8 20 36 Contribution 12 14 The supply of materials for the period is unlimited, but the machine hours are limited to 15,000 hours. In order to maximize the profit, we should using limiting factor analysis to solve the problem when there is only one limiting factor. Step 1: Identify the bottleneck resource. At sales demand level: Sales demand Machine hours per unit Total machine hours X 2,000 units 3 hours 6,000 hours Y 3,000 units 4 hours 12,000 hours 18,000 hours Thus, machine hours are the limiting factor. Step 2: Calculate the contribution per unit for each product. The contribution has been given at the above. X Y Contribution per unit RM 12 RM 14 Step 3: Calculate the contribution per unit of the bottleneck resource for each product. To calculate the contribution per unit of the bottleneck resource for each product, the formulae is: Contribution per units of the machine hours = Contribution Machine hours Product X = RM 12 3 hours = RM 4.00 Product Y = RM 14 4 hours = RM 3.50 Step 4: Rank the products from the highest contribution per machine hour to lowest contribution per machine hour. Production should be concentrated on product X first, up to maximum sales available, then product Y. Step 5: Finally, allocate the available resources using that ranking that we decided at step 4 and calculate the maximum contribution. Production plan Units produced Machine hours per unit Total machine hours Balance of machine hours 15,000 hours Product X 2,000 units 3 hours 6,000 hours 9,000 hours Product Y 2,250 units 4 hours 9,000 hours So, the maximum contribution is as follow: RM Product X ( 2,000 units x RM 12) 24,000 Product Y (2,250 units x RM 14) 31,500 55,500 Multiple limiting factors- Linear programming We can use limiting factor analysis when there is one limiting factor. However, when there is more than one of scare resources which restricts organisations activities, we can use linear programming to solve the problem. Firstly, we must defined the variances when we using linear programming. After this, we can define and formulate the objective. Thirdly, we can formulate the constraints to formulating the problem. Next, we must draw a graph to identify the feasible region and we can get the optimum production plan from the graph. Finally, we can solve the problem and get the maximum contribution by doing so. Example 3: A B Contribution per unit RM 20 RM 10 Machine hours per unit 6 hours 3 hours Kilos per unit 4 kilos 8 kilos Maximum available : Machine hours = 18,000 hours Kilos = 24,000 kilos What should be the production plan? To answer the example 3, we should use linear programming to get the optimum production plan because there is two or more of scarce resources. Step 1: Define the variances Let x = the number of units of the product A. y = the number of units of the product B. Step 2: Define and formulate the objective function. The objective is to maximize the contribution C, given by: Maximum contribution = 20 x + 10 y Step 3: formulate the constraints. The limitations here are machine hours and kilos. For the machine hours, product A required 6 hours and product B required 3 hours machine hours. So, total machine hours required = 6 x + 3 y For the kilos, product A required 4 kilos and product B required 8 kilos. So, total kilos required = 4 x + 8 y Constraints Utilised Available Machine hours 6 x + 3 y Ë‚ 18,000 Kilos 4 x + 8 y Ë‚ 24,000 Step 4: Draw a graph and identify a feasible region. For the equation 6 x + 3 y = 18,000 machine hours When x = 0, y = 18,000/ 3 = 6,000 When y = 0, x = 18,000/ 6 = 3,000 Draw a straight line between the point (0, 6000) and (3000, 0) on the graph to represent the line for machine hours constraint. For the equation 4 x + 8 y = 24,000 kilos When x = 0, y = 24,000/ 8 = 3,000 When y = 0, x = 24,000/ 4 = 6,000 Draw a straight line between the point (0, 3000) and (6000, 0) on the graph to represent the line for kilos constraint. The constraints can be show as below: The original constraints were Step 5: Determine the optimal solution Calculate the contribution earned at each point P, Q and R Point P = RM 20 (0) + RM 10 (3,000) = RM 30,000 Point Q = RM 20 (2,000) + RM10 (2,000) = RM 60,000 Point R = RM 20 (1,500) + RM10 (0) = RM 30,000 Point Q gives the maximum contribution. Step 6: Answer the question The optimal point is at x = 2,000 and y = 2,000. This gives a maximum contribution of C = (20 x 2,000) + (10 x 2,000) = RM60, 000 (c) Explain the management idea known as throughput accounting. State and justify your opinion on whether or not throughput accounting and limiting factors are the same thing. (18 marks) To reduce companys cost and improves the profitability, every companys managers are using cost accounting to help them on decision-making. Theory of constraints (TOC) or Throughput accounting (TA) is another method for decision making others than Standard Based Costing, Activity Based Costing and Marginal Costing. TOC/TA is new management accounting approach based on factors identification when constraints are restricts companies to achieving their goals and hence reduces companys profits. Throughput accounting is used when there are only few constraints, normally just one. The constraint can be a resource, company policy or management mindset. According to Goldratts ideas, TOC is forecasting on a limit capacity at certain critical points in any production plan. TOC can maximise organisations profit by increases the speed of producing through an organisation to eliminating bottlenecks. Additionally, throughput accounting is not costing because it does not allocate all expenses (variable and fixed expenses, including overheads) to the products and services. Thus, throughput accounting helps managers to get better management decision in order to improve organisations profits by three measurements. They are: Throughput (T) is the rate that company produces goal units. When the goal units are money, throughput is net sales (S) less total variable costs (TVC), usually is cost of raw materials ( T = S TVC ). However, T exists when there is only one product or service sold. Besides, finished goods of inventory in a warehouse are not count because it has not yet sold. Operating expenses (OE) is all others expenses except the total variables cost that used to calculate the throughput. Basically, OE is total cost to operating the production system. Fixed or partially fixed costs no difference in throughput accounting. On the contrary, there only have either total variable cost or operating expenses in throughput accounting. Examples for OE include maintenance, utilities, rental, etc. Investment (I) is total amount of money that invest in a new system to enhance its ability to improve the capacity, for examples machinery, inventory, building, and other assets and liabilities. Therefore, throughput accounting use difference formulas to make difference types of accounting decisions by combined the throughput, total variable costs and operating expenses: Net profit  (NP) = Throughput Operating Expense = T-OE Return on investment  (ROI) = Net profit / Investment = NP/I Productivity  (P) = Throughput / Operating expense = T/OE Investment turns  (IT) = Throughput / Investment = T/I We can use the above formulas when making a decision that related to changes in revenue, expenses or investments to get the right decision, which must generate a positive answer from one out of three questions below: Does it increase throughput? Does it reduce operating expense? Does it improve the return on investment? Finally, there are five steps in the TOC to help managers maximize the throughput which causes them to achieve organisations goals. The five steps are as follows: Identify the system constraints. There is an internal constraint? For example, in production, engineering or planning. There is an external constraint? For example, in the market. The constraints a resource or a policy? Decide how to maximise the output from the constraint. Prepare all other activities subject to this decision. While Non-constraints need to be subject to constraints. Consider the appropriate level of resources once the resource constraint has been identified. Therefore, the capacity constraints can be improved. Enhance the systems constraints. Once the constraint has been corrected, return to Step 1 to determine the next most serious constraints and duplication. In my opinion, throughput accounting and limiting factor is not the same thing but there are similarities and differences in between throughput accounting and limiting factor. For example, throughput accounting and limiting factor are using to assist companies to identify bottleneck resources instead to maximize companies profits. However, throughput accounting is used when there are very few constraints; often just one but limiting factor is used when there are one or more than one constraints. Besides, limiting factor is focus on working to obtain greatest contributions while throughput accounting is focus on the premise that the limited capacity in some critical point of any production plan. In addition, limiting factor maximise the organisations profit by using the best combination of available resources but throughput accounting is maximise the profit by increase the producing speed through organisation to eliminate bottlenecks. Throughput accounting calculates the products throughput as the selling price minus all variable costs. Variable costs or in another words cost of materials in throughout accounting included direct material costs only, labour and overhead costs are fixed and categories to total factory costs. In contrast, limiting factor calculated by sales price minus variable costs to get the contribution but variable costs in limiting factor are including the labour and overhead costs, this is difference from throughput accounting.

Literary Analysis In The Bean Trees by Barbara Kingfisher there are many different relationships between characters. Some are more important to the story, like the relationship that Taylor and Turtle share. Other characters that develop relationships are Taylor and Lou Ann, and Taylor and her mother, Alice. All of these relationships are also very symbiotic because the people rely on each other, without each other they would have much different lives. The author shows how Taylor grows through her relationships and the dependence they have on one another.Another important relationship that we see in The Bean Trees is the relationship between Taylor and her mother, Alice. Alice Is a single mother who raises Taylor on her own until Taylor Is old enough to move out of town. I believe that her mother serves as a role model for all of the other future women throughout the book. She raised Taylor as a confident young woman who would not be held back. Tailor's father, Foster, left her and h er mother before she was born, but Alice still has a very positive outlook on life.She tells her daughter that â€Å"trading Foster for you was the best deal this side of the Jackson Purchase† (6). She shows Taylor that she does not need her father, Foster, to love life because she has her. Love and support is found in this relationship especially from Alice to Taylor. Taylor says, â€Å"There were two things about Mama. One is she always expected the best out of me. And the other is that no matter what I did, whatever I came home with, she acted like it was the moon I had just hung up in the sky and plugged in all the stars† (13).Alice really motivated Taylor as her mother to go far In life and would praise her to let her know she is doing well. Since they had this strong mother and daughter relationship, Taylor has the courage o leave Pitman to escape motherhood and become the best person she could be, for her mother and herself. Taylor Greer, the main character, lef t her home in Kentucky to avoid becoming pregnant and being a young mother like every other girl. This seems ironic because as soon as she leaves, she is given a baby from an Indian lady.She names the baby girl Turtle. Besides the relationship that Taylor had with her mother, she never had anyone depend on her. The relationship between Taylor and Turtle is the first example of dependence in the story. I believe that Turtle was given to Taylor to present the importance in relationships because the baby is fully depending on Taylor to take care of her. Also, I think there was a reason that she names the baby Turtle. Taylor says you're like a mud turtle. If a mud turtle bites you, it won't let go till it thunders† (22).This quote Is showing that Turtle does not let go of Taylor easily and this also shows that the relationship between them Is growing stronger. Turtle trusts her and Is starting to look at her Like a mother figure. When Taylor got to a motel with the baby she wrote to her mother, â€Å"l found my rights, Mama. They're coming with he may not be able to be the best provider. She sees Turtle as a â€Å"right† or something that she now has ownership of. When Taylor moves to Tucson she meets and moves in with Lou Ann, a single mother, who now Taylor depends on.They end up helping each other along with life and act like one family with their children. In the beginning, Taylor acted as if she did not want them to act like family, â€Å"Lou Ann, I moved in here because I knew we'd get along. It's nice of you to make dinner for us all, and to take care of Turtle sometimes, and I know you mean well it's not like we're a family, for Chrism's sake. You've got your own life to live, and Vive got mine. You don't have to do all of this stuff for me† (85).This shows that Taylor might feel uneasy to depend on somebody else at the time, even though she knew she needed help. When she starts to realize this, she thinks, â€Å"We had worked things out: I cooked on weekends, and also on any week night that Lou Ann had kept Turtle she would do the vacuuming† (107). Taylor says move got your own life to live and Vive got mine† meaning they are not going to get involved with each other's lives. In the second quote, it shows that they are beginning o work together on living and would make each other dinner or help clean.Lou Ann would also have Turtle for the night while Taylor rested. As much as she did not want to admit it, Tailor's relationship grew with Lou Ann and she became much more dependent on her. The relationships in the book between Taylor and Turtle, Lou Ann and Taylor, and Taylor and her mother are all significant to show that dependence is a major theme in The Bean Trees. Barbara Kingfisher uses relationships to show dependence in order to say to the world that you cannot get through life without guidance or having someone's shoulder to lean on.

October 25, 2015 Introduction For many patients, language and culture set the background and context for the procurement and application of their health literacy skills. Health literacy is defined as the degree to which an individual is able to access, understand, and communicate information in order to promote and maintain their health [1]. However, a third of U.S. adults—77 million people—would have difficulty with common health tasks, such as following directions on a prescription drug label or adhering to a childhood immunization schedule with a standardized chart [2]. Limited health literacy has frequently been found as a strong risk factor for inadequate health knowledge, reduced self-care ability, increased morbidity, and mortality [3]. People with low health literacy tend to experience higher rates of chronic illness and are less likely to use preventive health services when compared to people with high health literacy [3]. Research that focuses on health literacy, especially of minority populations, is important because groups such as immigrants, refugees, and non-native speakers of English are more likely to experience limited health literacy [3]. The impact of limited health literacy disproportionately affects lower socioeconomic and minority groups.

Culture The Minds Eye What The Blind See - 1691 Words

According to cultural anthropologist Edward Burnett Tylor, culture is a â€Å"complex whole which includes knowledge, belief, art, morals, law, custom and any other capabilities and habits acquired by man as a member of society.† In other words, culture is a concept that social organizations practice in order to explain certain phenomena in nature whether through mythology, rituals, art, music, and language. However, as explained by Ethan Watters in â€Å"The Mega Marketing of Depression in Japan,† culture is not permanent, since it has the ability, and more than ever in the present society, to â€Å"move across boundaries of race, culture, class, and nation† (Watters 519). In addition, as demonstrated by Oliver Sacks in the articled called â€Å"The Mind’s Eye: What the Blind See,† it is a mistake to think that individuals are bound to behave in a way that culture told them to behave. Instead, individuals are free to create his or her own unique ex perience of interpreting the world. We might consider the â€Å"reality† that we live in to be fiction to the extent that we are willing to use different faculties and analyze what we are witnessing; this gives us the power, as individuals, to think and search for each of us’s unique interpretation of reality. .

Are Harry Potter Harmful for Children Free Essays

Are Harry Potter Books Harmful for Children? As far as I’m concerned, the Harry Potter series are quite suitable for children to read. As we all know, this set of books is written about a boy who is a wizard, and he fights with the devil for the justice, during the process it also show us how to treat our real friends and our family. Some parents and censors consider this book harmful for children to read and try to ban it, because of the manipulation, lying, violence, witchcraft (which they think is against god) and rebellion in Harry Potter books are unfit for children to read, for they will imitate the same thing and learn something adults don’t want them to acquire that early. We will write a custom essay sample on Are Harry Potter Harmful for Children or any similar topic only for you Order Now But I have to say it is just a book, in today’s world if a child wants to know these things, all he need is just to go online and google it, so if they want to protect their children, why don’t they ban the Internet? If you think that because there is witchcraft and devils in the novels which supports satan and defies God, I have to say that you are definitely wrong. If you have ever read this set of books, you’ll find out that it’s just the background and a part of this novel. The witchcraft is just the background which the author set to entertain readers. , because this field is very attracting and can satisfy children’s curiosity. And it also keeps children’s minds open. This world is nothing like the real world, so they can imagine lots of things which can develop their imagination and creation. When J. K. Rolling wrote about this darkness part, she also mentioned the right part. And it is a tale of good triumphing over evil. I think we can’t see this series from just one perspective. We can’t deny it for the author writes about the darkness and the devil then forget that from all perspectives, what she real emphasize and want readers to learn is the braveness, the justice, the friendship, the love, and the family. It taught our children, even adults how to become an upright person. For example, when Harry Potter, Hermione and Ron play â€Å"chess†, for the friendship and the justice Ron sacrifice himself to save Harry. In this real world, many adults can’t do the same thing when they meet with difficulties. If we banned this book, what about Snow White? It i also filled with wicked, blackness things. Instead, we taught our children the correct and proper way by telling Snow White when they are very little. Therefore, why can’t we treat the Harry Potter series the same way or even kinder. It is also a tale for children to learn the world by means of using the metaphor, changing the scene to the magic world. The dark part is not the point, but the love, the moral part that hit the nail on the head. If parents really worried about the darkness part, he/she can read the book for children while explain these for children instead of banning it. Although the censors think that their efforts are benefiting children, in the long run it is destroying them. We are destroying our children’s imagination. We put them in the same frame we set up for them. We decide which kind of books they read, which friend of children they make friends with, which kind of games they play, etc. If all these matters had to be approved and set up by adults, each child would be a mindless, characterless character. There would be no unique qualities to distinguish one from another, all children being of the same mold. If our children grew up with out creativity or imagination and only knew what was approved, this world would become numbing, vapid and meaningless. The Harry Potter series is encouraging the growth of a child’s imagination, allowing our children to grow into fully functioning, creative adults. As for the religious part, they say the book encourages witchcraft. I think they are too mean, too extreme. There are lots of fairy tale and legend for children about witchcraft or magic. We can’t ban and criticize all these things. It is the same with Harry Potter. Just because Harry Potter is so popular and attractive to children, so they afraid the witchcraft will take the place of god, and they try to ban it. They say it’s harmful for children actually on behalf of their own interest, not really for the children’s sake. In conclusion, the Harry Potter books are not harmful for children. On contrary, it will enhance children’s moral standard and imagination. Therefore, we should really recommend our children to read it. How to cite Are Harry Potter Harmful for Children, Papers

Diamond and Cubic Zirconium free essay sample

Diamonds shine and sparkle. Diamonds are very old and are made of a very basic mineral. They are a symbol of portable wealth and thought of when searching for engagement or wedding rings. Money may or may not be an issue, real is better than fakes because value, different colors, and they last for generations. Some people will disagree and think that any gem will do when looking for jewelry. Most people will buy the cheapest stones they can buy. This paper will inform and enlighten any reader to how real diamonds are better than fakes ones. To understand the difference between real and fake, a person needs to know some background on how diamonds are formed, and the process in which diamonds go from ground to what we see today, and some history about diamonds. To understand why fakes are less superior a little history on how they are created and why to choose such a gem would be a costly mistake. Diamonds are made of carbon and with incredible pressure and heat. The heat is said to be at least 2000 degrees, but not much higher than that because conditions will no longer be suitable for their formation. Diamonds come from deep in the earth, around 90 miles or 150km. (Wisegeek. com, 2010). Magma moves diamonds closer to the surface and when the magma cools, it forms a rock called kimberlite. Diamonds may or may not be found in this rock, but it is a likely source. There are several mines throughout the world. South Africa is the largest diamond producing country. Once diamonds are found the stones are then ready for processing. There are four steps to a finished diamond cleaving, cutting, bruiting, and grinding and polishing. The last two are done at the same time. Harlow, G, 1998). When a person goes looking for a diamond most do not know exactly what they are looking for. The amount of money they have to purchase the diamond is usually foremost on the mind. When purchasing a diamond one must consider the Four C’s. The Four C’s are Color, cut, clarity, and carat. Gemological Institute of America (GIA) the world’s foremost authority on diamonds, colored stones, a nd pearls has created the clarity scale and the D-to-Z color scale for diamonds. Any company that has diamonds uses these scales to evaluate the diamonds they have. Most diamonds found in jewelry stores run colorless to near colorless, with slight hints of yellow or brown. The color scale starts with the letter D, representing no color or colorless and with more color the higher on up the scale. Diamonds can come in a variety of colors. The most valuable color is red. Red is also the rarest then comes the colors green, orange, blue, and finally pink. Colorless is still the most popular color people tend to choose for wedding rings. (Renken, S, GIA, 2010). The closer a diamond is too colorless, the more valuable and beautiful it is. The diamondbuyingguide. com, 2010) Clarity is seeing if the diamond has any sort of marks either internal or external. A diamond that has no flaws is very rare. A jeweler uses the GIA grading scale that contains 11 grades ranging from (FL) Flawless to Inclusions 3 (I3). Cut is what makes the diamond shine and sparkle. If the cut is wrong, the diamond will not shine as much as it should. The Scale ranges from excellent meaning that the diamond is cut to perfection and will shine to the most of its ability. The major parts of a diamond are the crown, girdle, and the pavilion. Carat is the last C and is what makes the value of the diamond. If a person were to have two diamonds of the same weight, they can have different values depending on the other members of the Four C’s. (GIA, 2010). A diamond is divided into 100 points, which is equal to 1 carat or 0. 2 grams. The cut of the diamond is so important that the cut is often measured to the hundred thousandths of a carat. Any stone over 1 carat is shown in carats and decimals. For example, if a diamond that measures 2. 08 ct. the decimal shows how many points that stone has. The more points the more expensive the diamond can be. The largest diamond ever found is called The Cullinan. It was discovered in 1905 in South Africa. Originally, it weighed 3,106 carats, but in 1907, it was cut into nine major stones. One stone that might ring a mental bell is called the Star of Africa. This stone weighs in at 530. 20 carats and is set in the royal scepter and housed in the Tower of London. Another of the most popular large diamonds around is the Hope Diamond. Its original weight was 112 3/16 carats, but now years later it is 45. 52 carats and mounted in a pendant. (Harlow, G, 1998). There are many diamonds that are well known and very large. Some other names you might recognize are the Tiffany, The Koh-i-Noor â€Å"Mountain of Light†, and The Centenary just to name of few. The cutting of a diamond has several steps. The jeweler needs to visualize what the stone will look like as a finished product before the next step of cleaving. Cleaving is the best way of dividing a diamond. Cleaving has become easier when we started using lasers to guide in the cutting process. Cleaving splits the diamond on one of its four planes that is weak. A person who cleaves must be very good at what he or she does. If the person does not do this process correctly, it will result in a crushed diamond. Marking a diamond will help in making a notch, this notch will make cleaving easier. To notch a diamond a jeweler needs to use another diamond. Only a diamond can cut a diamond. Cutting is next which is removing a large section of diamond that is not being worked on by the jeweler. Bruting, plainly put is using brute force to round edges. Grinding and polishing come next; grinding is done by using a mixture of crushed diamonds and oil to shape the diamond to the finished product. Polishing is just that, making the diamond shine. Harlow, G, 1998). Diamonds are used to fashion a wide variety of other hard substances, one such substance is tungsten carbide. Diamonds are also used as a cutting tool, an abrasive, and either a powder or paste for grinding and polishing. Throughout history, a person can read about kings and queens having such enormous wealth that they wore many diamonds. Diamonds were wor n by kings and queen as early as the 1300’s. Diamonds were first worn in crowns, coronets and jeweled garlands (also known as rosary). Over the years, diamonds were added to gowns and collars then to accessories like combs and mirrors. Diamonds have grown in popularity ever since. If we look into the past, we see kings; queens and other people of station wear something with diamonds. With the rise of the movie industry, jewelers began to place their diamonds in the movies for free if the movie people would list the name of the jewelry company in the credits. Jewelers started to open stores in Hollywood to attract the rich and famous. This is also were diamond sales sky rocketed. Diamonds helped promote the movie industry and the movie industry promoted the diamond industry. We have seen diamonds used for many different purposes. Diamonds have become the objects of desire in movies as a forbidden treasure or curse, we see people trying to smuggle them in coats, hats, linings and even in human bodies. Movies had people use diamonds as a way of paying for goods or services. An example would be when Linda Fiorentino, in The Moderns (1998), tosses a diamond earring on a cafe table in exchange for a glass of whiskey or Liam Neeson, as Oskar Schindler in Schindler’s List (1993), pours a mountain of diamonds on a SS commandant’s desk in payment for a trainload of doomed Jews. One of the most popular diamond look alikes is Cubic Zirconium (CZ); this is a laboratory created gem. A gem that is created in a laboratory is considered synthetic because it was not created by natural means. This is a popular stone to get if money is an issue, the next popular is the synthic Maissanite. Cubic Zirconia became popular in the 1970s. Cubic Zirconium rates higher on the color scale and are almost as brilliant as a real diamond. A Cubic Zirconium rates an 8. 5 on the MOH’S scale and a diamond rates a 10. A Cubic Zirconium weighs more than a diamond of the same size; this is due to the Cubic Zirconium being denser. penoir. com, 2009). A real diamond will keep its value through the whole of its life where as the fake Cubic Zirconium will not be worth as much as when you bought it. Some jewelers will offer a lifetime guarantee for the gem, but why would you need it if the gem were not expensive in the first place. Why have a stone that has no history? History is what gives everything value. Do you think that having a gem that might be 3 million years old is better than a laboratory created gem? Do you think that whoever is getting the diamond would like it more if it had the possibility of being a part of one of the largest stones available?
