Gold Quality measures: Gold's purity is measured in karats. The term "karat" harks back to the ancient bazaars where "carob" beans were used to weigh precious metals. 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. 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.
