Karat
A variation of the word "carat", (used to describe the weight of a gemstone), "karat", with a "k" is used to describe the purity of gold. Gold is often alloyed with silver, copper, and/or other metals to improve its strength and durability. Products made from gold are marked to show how much actual gold is contained in the product. Items marked 24K are 100% pure gold. Items marked 18K or 750 have 750 parts gold out of 1000, or 75% pure gold. Items marked 14K or 585 have 585 parts out of 1000, or 58.5% pure gold.
