Questions About Onyx 18k Gold
- Is 18K gold good for earrings?1 Answer1stDibs ExpertNovember 14, 2023Yes, 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, 2023The 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.
