Facts You Need To Know About GOLD by phollybee(m): 4:07pm On Jul 14, 2014 |
Pure gold (fine gold) is softer than pure silver but harder than tin. Its beauty and luster are unmatched by any alloyed gold. The extreme malleability, ductility, and softness of pure gold make it practically useless for jewelry applications. The addition of alloying elements (other metals) to gold are used to increase the toughness and hardness of the metal. While almost any metal can be alloyed (melted) with gold, only a select group of metals will not dramatically change the color or make the metal brittle. For example, we never mix indium with gold because it turns gold purple and gives gold the workability of glass. What is a Karat ? Over time, certain percentages of gold have become legally recognized "karats." The karat indicates the amount of gold as a percentage of the total, i.e. 24 karat is 100 percent gold. In karated gold, there is a balance of metals in the non- gold percentage called alloys. These metals provide the various colors and hardness of karated gold. 18 karat gold is 18 parts gold and 6 parts alloys such as copper, nickel, silver or zinc. 14 karat gold is 14 parts gold and 10 parts alloy. Gold standards vary around the world. In the United States, 18, 14, and 10 karat gold are the only karats allowed to be sold as karated gold. What is the difference between 14 karat and 18 karat gold? 18 karat gold means that the metal is 18 parts out of 24 pure gold, or in other words, 75% pure gold. 18 karat gold is the standard for European jewelry. 14 karat gold is 14 parts gold, or 58.5% pure gold. It is the standard for American jewelry. What is used to change the color of gold? The addition of alloying elements (other metals) to gold are used to increase the toughness and hardness of the metal, as well as change the color. Adjusting the proportions of coloring agents provides the array of colors on the market. Additional metals enhance properties such as castability, grain size, hardness, corrosion resistance, color, workability, ultimate strength, and others. These additions can dramatically change the properties of the karated metal for better or worse. For example: 18 karat rose gold is 75%, or 18 parts fine gold and 25%, or 6 parts copper. It is the rich red copper combined with the pure yellow gold that creates a warm rosy tone. 14 karat white gold is 14 parts gold and 10 parts white metal, either nickel or palladium. These white metals dominate the color, creating a warm gray tone. Typical alloying elements and their color effect : Copper - Reddening Silver - Greening Zinc - Bleaching Nickel - Whitening Palladium - Whitening Examples of the compositions of different colors are: Yellow Gold: copper, silver, zinc White Gold: nickel, manganese, palladium, zinc, copper Red (Rose) Gold: copper Green Gold: silver What is the difference between a carat and a karat? A carat is a unit of weight for gemstones, where one carat equals 1/5 of a gram, or 200 milligrams. 142 carats equals one ounce. Carats are divided into 100 units, called points . For example, a half-carat gemstone would weigh .50 carats or 50 points. The important thing to note is that carat is a unit of weight, not a unit of size. A one carat stone that is dense will be smaller than a one carat stone that is less dense. For example, sapphires are denser than diamonds, so a one carat sapphire will be smaller than a one carat diamond. A karat is not a unit of weight. The word karat refers to the amount of gold in a particular item. Karats are measured in units of 24, where 24 karat gold is pure gold. 18 karat gold is 18 parts gold and 6 parts alloys such as copper, nickel, silver or zinc. 14 karat gold is 14 parts gold and 10 parts alloy. 13 Likes

@op, facts depicited that the world cup have about 72-76 karats of gold. Then does it mean by the standard of your estimation that 24 karats of gold which has been legally accepted as the standard is more purer, refined, and greater than that of the world cup? Need more insightful explaination, no offence intended. |

Need more insightful explaination, no offence intended. There is nothing like 72-76 karat gold. The highest you can get is 24 karat which is pure gold. op you can also have 22 karat gold. Then the locally-made gold varies depending on how much gold the goldsmith puts in to the jewellery. |
