Do sapphires conduct heat?
1 Answer
Yes, 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.
