Difference Between 24K, 22K, 21K, and 18K Gold

The 'K' in gold stands for Karat, which measures purity out of 24 parts. 24K gold is 99.9% pure, making it the most valuable but also the softest. It is typically sold as coins or bars (bullion) for investment purposes.

21K gold is the standard for jewelry in Saudi Arabia. It contains 87.5% gold mixed with usage metals like copper or silver for durability. It offers a beautiful deep yellow color and retains high resale value.

18K gold (75% purity) is more durable and affordable, often used for diamond-studded jewelry or everyday wear, though it has a lower resale value compared to 21K.
