When shopping for black tourmaline, there are a few tips to help you determine if what you have is real or not.
First, it is important to check the color of the tourmaline. Real black tourmaline should be a deep, dark black. If the color is more gray, grayish-black, or has grey stripes, it is likely that it is not real tourmaline.
Second, take a look at the shape and size of the stone. Tourmaline that is real should have smooth edges and be relatively uniform in size. If the edges are sharp or jagged, this could be a sign that the stone is not genuine.
Third, you can check the stone's reflection. Real black tourmalines tend to have a glossy or slightly sparkly finish which is a sign of quality. Groupings of cross-hatched lines or streaks should also be visible with real tourmaline.
Finally, you can take it to a gemologist or be sure to purchase from a reputable dealer who will perform an authenticity test. If a gemologist determines that the black tourmaline is not genuine, they can suggest another gemstone that may better fit your criteria.
