Questions About No Heat Orange Sapphire
  • 1stDibs ExpertApril 5, 2022
    A 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.
  • 1stDibs ExpertMarch 22, 2022
    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.
  • 1stDibs ExpertApril 5, 2022
    One of the best ways to tell if any orange sapphire is real is to give the gemstone a “breath test.” Breathe on the sapphire to create a fog — if the condensation clears up within a few seconds, the sapphire is genuine. You can also try the “scratch test” by scraping a key or coin across the sapphire’s surface. Sapphires are second only to diamonds on the Mohs Hardness Scale, so scraping shouldn't leave a mark on a real sapphire. Shop a collection of orange sapphire jewelry from some of the world’s top sellers on 1stDibs.
