Gold jewelry is a look that has never gone out of style and is as popular as ever. Purer gold jewelry does not cause staining or tarnishing like inferior alloy blends. Usually if someone has a problem with staining on their skin it is due to their body and not the gold.
Gold is very malleable and as such can be made into just about any shape including tiny hair like strands and thin sheets.
One of the main things most people look for when purchasing gold jewelry is the purity. The jewelry industry has a universal system for identifying this factor.
Chances are the ring on your finger is marked 18K, 14K, or 10K, with the K standing for karat, the system used to describe the percentage of pure gold an item contains.
The higher the karat number, the higher the percentage of gold in your gold jewelry.
24K gold is pure gold.
18K gold contains 18 parts gold and 6 parts of one or more additional metals, making it 75% gold.
14K gold contains 14 parts gold and 10 parts of one or more additional metals, making it 58.3% gold.
12K gold contains 12 parts gold and 12 parts of one or more additional metals, making it 50% gold.
