Questions About 12k Jewelry
- Is 12K gold real?1 Answer1stDibs ExpertFebruary 21, 2024Yes, 12K gold is real, but that doesn't mean that the material is pure gold. 12K gold is actually an alloy that is 50% pure gold and 50% other metals. The resulting alloy is highly durable and resistant to scratching and fading. Its hardness makes it difficult to shape into rings, so most 12K gold jewelry consists of necklaces and earrings. On 1stDibs, explore a wide variety of gold jewelry.
- Can you buy 24k gold jewelry?1 Answer1stDibs ExpertApril 12, 2024Yes, you can buy 24k gold jewelry. However, 24-karat gold is a much less commonly used material than 14-karat and 18-karat gold. As 100% pure gold, 24-karat gold tends to be softer and more susceptible to scratching and breakage, making alloys a more popular pick for jewelry makers to use when crafting pieces. Find a large collection of gold jewelry on 1stDibs.
