About 18K Pink Gold (Japanese style)

How much it's worth
The melt value of a 18K Pink Gold (Japanese style) piece is gold spot price × 0.750 × weight (g), because only 75.0% of the metal is gold. A buyer then deducts roughly 5–15% for refining and margin, so a cash offer lands just under that figure. Higher-karat gold packs in more gold per gram, so it carries a higher melt value — but it's also softer and scratches more easily, which is why everyday jewelry often uses lower karats.

- A. Yes. 18K is genuine gold — it's 75.0% pure gold by weight, alloyed with other metals. It is not gold-plated or gold-filled; the gold runs all the way through.
- Q. Why is 18K Pink Gold (Japanese style) pink?
- A. The color comes from the metals mixed with the gold. Nickel and palladium are the bleaching metals — they cancel gold's yellow to give a white tone.
