For many women new to jewelry, the “K” marked on gold pieces can be confusing. This post makes everything clear—read on to quickly understand the differences, similarities, and applications of 24K, 18K, 14K, and 10K gold, and see why 18K gold jewelry is especially suitable for modern women in Hong Kong and Taiwan.
What is Karat Gold? Comparing Purity and Function
“K” stands for karat, the unit of gold’s purity. 24K gold is pure gold—100%—while the lower the number, the less gold (and the more other metal alloys) the piece contains.
| Type | Gold Content | Features & Design Applications |
| 24K | 99.9% |
Richest color, extremely soft, easily deformed; typically used for pure gold bars, collectibles, or simple designs; easily scratched or bent in daily wear. |
| 18K | 75% |
Elegant hue, moderate hardness, most common in high-end jewelry; great for diamond/gem setting and intricate detail. |
| 14K | 58.3% |
Softer tone, very durable, ideal for everyday rings or bracelets; more budget-friendly but with a slightly less luxe finish than 18K gold. |
| 10K | 41.7% |
Hardest and most durable but lighter in color; used for budget-conscious buyers or ultra-durable entry-level designs. |
