- 1stDibs ExpertFebruary 13, 2023Van Cleef and Arpels jewelry is 18-karat gold, not 14-karat. The luxury jewelry designer makes necklaces, bracelets, rings, earrings and cufflinks in 18-karat white, gold and rose gold. On 1stDibs, shop a variety of Van Cleef and Arpels jewelry.
- 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.
