Questions About French 18k Plat
  • 1stDibs ExpertNovember 21, 2023
    Whether a wedding band should be 14K or 18K depends on your personal preferences. Because it contains more pure gold, 18-karat gold will usually show off a richer color and be less likely to fade over time. On the other hand, 14-karat gold is less prone to scratching and damage because it has more alloy metals. Explore a large collection of gold wedding bands on 1stDibs.
  • 1stDibs ExpertNovember 14, 2023
    Yes, 18-karat gold can be good for earrings. Because it is an alloy, 18-karat gold is more durable and scratch-resistant than pure 24-karat gold. You can find 18-karat gold in rich warm yellow, cooler white with warm undertones and light pink rose. On 1stDibs, explore a large collection of gold earrings.
  • 1stDibs ExpertNovember 1, 2023
    The difference between 14K and 18K white gold stud earrings comes down to the content of the precious metal alloy. Stud earrings made of 14-karat white gold are 58.3% gold and 41.7% base metal, while 18-karat gold is 75% pure gold and 25% other metals. As a result, 14-karat white gold tends to be stronger and more resistant to scratching, and 18-karat gold will have a more noticeable warm-glowing yellow tinge. On 1stDibs, shop a range of white gold stud earrings.
