From modern U.S Treasury to the ancient Egyptians, there are few metals that have had such an influential role in human history as gold. Gold has a long history as a valuable metal and its history is far from over. flakes of gold have been found in Paleolithic caves dating back as far as 40,000 B.C. In 1792 Congress passed the Mint and Coinage that established a fixed price of gold in terms of U.S dollars.
“k” indicates purity, or how much of the metal in a piece of jewelry is gold, Pure Gold or 100% Gold is referred to as 24k Gold.
14k gold is composed of 58.3% gold and 41.7% of other metals. 18k gold is composed of 75% gold, which is alloyed with other metals to make it strong enough for everyday wear.
As the percentage of pure Gold decreases, the strength of the metal increases, therefore as the percentage of pure Gold decreases, the price of the metal also decreases:
- 24 karat Gold is 100% pure Gold and is too soft for making jewelry
- 18 karat Gold is very popular for fine jewelry, good balance of strength and value
- 14 karat Gold very popular for jewelry. Good balance of durability and value
- 10 karat Gold Not acceptable for jewelry
