- 1stDibs ExpertNovember 8, 2023Whether 14-karat or 18-karat white gold is better for a wedding band depends largely on your preferences. If you like the look of white gold with a warmer tone, you may wish to opt for 18-karat gold because it often appears yellower due to its higher gold content. On the other hand, 14-karat white gold wedding bands tend to be durable, making them a good option for people most concerned with keeping their rings scratch-free. Find an assortment of white gold wedding bands on 1stDibs.
