Gold jewelry is manufactured in 14, 18 or 22 carat gold. Carat, however, is an important measure used to indicate precious stenar weight and should not be confused with carats. Gold content can be specified either in parts per thousand or in carats, see comparison below: To view the contents of the gold used is described as the gold content in carats or in the number of parts per thousand.

Pure gold is not hard enough to use in jewelry, so instead used an alloy such as copper, silver and / or palladium.

For example, is the lower limit in the United States 10 carat, 9 carat in England and in Sweden is 14 carats. The jewelry sold at Lama Stone is available in either 14 carat (58.5 percent, 585 parts per thousand) or 18 karat (75 percent, 750 parts per thousand).
