What Is 18K Gold?
18K gold is an alloy consisting of 75% pure gold and 25% other metals such as silver, copper, or zinc. The “18K” refers to 18 parts gold out of 24, offering a balance of beauty, durability, and affordability. This makes it highly desirable for both jewelry and investment-grade gold bars.

|---|---|---|---|---|
| 24K | 99.9% | Pure | None | Investment bars, coins |
| 22K | 91.7% | High gold | 8.3% alloys | Jewelry, coins |

18K Gold vs 24K & 22K – Which Should You Choose?

| Color | Bright yellow | Slightly dull | Rich & customizable |
| Durability | Very soft | Soft | Strong & durable |
| Best For | Investment, coins | Premium jewelry | Everyday jewelry & bars |
