Questions About Sapphire Jewelry No Heat
- What is a no-heat sapphire?1 Answer1stDibs ExpertApril 5, 2022A no-heat sapphire is a sapphire gemstone in its natural state. It differs from sapphires that undergo heat treatment to enhance their surface. Generally, no-heat sapphires are smoother, while heated sapphires are harder and more lustrous. Shop a range of sapphire gemstone jewelry on 1stDibs.
- Do sapphires conduct heat?1 Answer1stDibs ExpertMarch 22, 2022Yes, sapphires conduct heat. In fact, a real one won't melt until it reaches a temperature of 3,711 degrees F. As a result, one way that experts test sapphires to determine if they are real is to heat them to high temperatures. Find a collection of sapphire gemstone jewelry on 1stDibs.
