YELLOW GOLD
Pure, 100% fine gold is 24 karat. This is a rich, deep golden color that has been used for jewelry historically but is too soft for general purpose jewelry. Here are a few notes about "karat gold":
- 18 karat gold means that the metal is 18 parts out of 24 pure gold, or in other words, 75% pure gold. The other 6 parts (25%) consists of an alloy of other metals. 18 karat gold is the standard for European jewelry.
- 14 karat gold is 14 parts gold, or 58.5% pure gold. It is the standard for American jewelry.
- In addition to the proportion of pure gold, the term "karat" is used to signify solid gold alloys versus gold platings or gold-filled pieces of jewelry.
