Understanding Gold Purity and Karats

Gold has been prized for centuries for its beauty and rarity. The purity of gold is measured in karats (K), which indicate how much pure gold is present in a piece of jewelry. Knowing how karats work is essential for anyone buying or selling gold.

What Are Karats?
Pure gold is 24K, or 100% gold. However, 24K gold is very soft, so it’s mixed with other metals—such as silver, copper, or zinc—to make it stronger. The karat number tells you the percentage of pure gold in that mixture. For example:

  • 18K gold is 75% pure gold and 25% other metals.

  • 14K gold is 58.3% pure gold.

  • 10K gold contains 41.7% pure gold.

How Karats Affect Gold Jewelry
Higher-karat gold has a richer, more vibrant color and higher intrinsic value, but it’s also softer and more prone to scratches. Lower-karat gold is more durable and often used for jewelry designed for everyday wear. The trade-off between purity and strength determines both beauty and practicality.

Identifying Gold Karats
Most gold jewelry has a small hallmark or stamp showing its karat rating—typically found on the inside of a ring band or on the clasp of a necklace. In the United States, the Federal Trade Commission requires this marking. Jewelers and professionals may also verify purity using electronic or X-ray testing devices for precise results.

Real-World Gold Purity Calculation
To estimate gold purity, divide the karat number by 24. For example, a 14K gold ring (14 ÷ 24) equals 0.583, or about 58.3% pure gold. In practice, small variations can occur, so professional testing ensures accuracy before buying or selling.
