14K vs. 18K Gold: What's the Difference?
14K or 18K? Both are genuine gold. Their pure-gold content differs, but karatage alone says little about how a chain feels to wear. At NTHIRTYTHREE, we choose 14K / 585 gold for classic pieces made to become part of everyday life.
Side by side
| 14K / 585 | 18K / 750 | |
|---|---|---|
| Pure gold | 58.5% | 75% |
| Other alloy metals | 41.5% | 25% |
| Color | depends on alloy | often richer |
| Material cost | generally lower | generally higher |
Choosing a chain for everyday wear
18K contains more pure gold per gram. For a chain you plan to wear regularly, it is also worth looking at its construction, finish and feel.
Construction, weight, craftsmanship, how often you plan to wear it and the look you prefer all matter.
Depending on the exact alloy composition, 14K can also offer greater resistance to deformation than higher-purity gold.
