Gold Quality: Gold’s purity is measured in karats. The term “karat” dates back to the ancient bazaars where “carob” beans were used to weigh precious metals. Gold used in jewelry is mixed with harder metals for strength and durability.
The higher the percentage of pure gold, the higher the karat. 24 karat is pure gold, but its purity means it is more expensive and less durable than gold that is alloyed with other metals. Different alloys are used in jewelry for greater strength, durability and color range.
Such a metal in its purest state is very soft and impractical for making jewels.To create jewelry that is practically wearable, gold has to be alloyed with other harder metals in the required proportions to make it malleable and durable.
The karatage of the jewelry will tell you what percentage of
gold it contains: 24 karat is 100 percent, 18 karat is 75 percent, and 14 karat is 58 percent
gold. When comparing gold jewelry, the higher the number of karats, the greater the value.
While Standard gold is 24 carat (100% pure gold), in India, it is 22 carat or 916, ie 91.6% pure gold and the rest includes metals like copper and silver. To be in a solid form, and the best possible purity is 91.6 Percentage… So good quality gold is called as 916 gold
The common Gold alloy to be used in any good quality gold jewel is 22 Kt Gold. It means that the gold is 91.6 % pure and hence the name 916 Pure Gold, an internationally accepted standard.
