Generally speaking, you can find our pearl jewelry is marked 18K gold and 14K gold. What is 18K or14K gold? Are there any differences from pure gold? Karat(carat) is called for K for short. The carat (abbreviation ct or kt) is a measure of the purity of gold alloys, 24 carat being pure gold. In the United States and Canada, the spelling karat (abbreviation k or kt) is used. The higher the karat number, the higher the percentage of gold. Here is some information for gold with different karat.
The carat system is increasingly being complemented or superseded by the millesimal fineness system in which the purity of precious metals is denoted by parts per thousand of pure metal in the alloy.The most common carats used for gold in bullion, jewelry making and by goldsmiths are:
24 carat (millesimal fineness 999 or higher)
22 carat (millesimal fineness 916)
21 carat (millesimal fineness 875)
20 carat (millesimal fineness 833)
18 carat (millesimal fineness 750)
15 carat (millesimal fineness 625)
14 carat (millesimal fineness 585)
10 carat (millesimal fineness 417)

Maybe you are puzzled why are other metals mixed with gold. As a matter of fact, pure gold is soft and isn't practical for daily wear. Other metals are mixed with it to make it more durable (and to lower its cost).
When metals are added to the gold the result is an alloy, a blended mixture of the metals that you can think of as a very expensive cake batter. Solid gold is a term that can be used to describe an item that's at least 10K (in the US) gold all the way through. Even though it's a gold alloy--18K, 14K, or anything down to 10K--it can be called solid gold.
Solid gold is durable, so it is a better choice for jewelry you'll wear regularly. If you have allergies to nickel or other metals, choose items that have high gold content, such as 18K or 22K gold jewelry.
