18K white gold or platinum 950 for your wedding band

Both are white, but they differ in weight, colour stability, care and price. Compare them point by point to choose a band for life.

Written by Kim Bảo Minh Châu

White wedding bands are a favourite for couples. The two main choices are 18K white gold and platinum 950. Side by side in the case they look almost the same; the difference shows after a few years of wear.

Composition

18K white gold (750): 75% gold, the rest white alloying metals such as palladium and silver. The surface is usually rhodium-plated for a bright white.
Platinum 950: 95% platinum, 5% alloy. Naturally white, no plating needed.

Comparison

Criterion	18K white gold	Platinum 950
Colour	Bright white from rhodium; plating wears after 12 to 24 months, showing a faint warm tone	Naturally grey-white, never changes
Weight	Lighter	About 30% heavier for the same size
Scratches	Scratches remove metal	Scratches displace metal, less loss
Stone security	Good	Excellent, tough and pliable prongs
Care	Periodic re-plating	Polish when you want the shine back
Price	Lower	Higher due to weight and harder craft

Choose by habit

Worn constantly, hands-on work: platinum keeps its colour and loses less metal.
Prefer a lighter ring, happy to re-plate: 18K white gold.
Two metals for a couple: fine, but a wedding band worn next to an engagement ring is best in the same metal so the two do not wear each other down.
