Black tourmaline is a wide range of tourmaline, which is a crystalline boron silicate mineral. Based on Yulia Van Doren, creator of Crystals: The Trendy Information to Crystal Therapeutic and founding father of Goldirocks, it is truly probably the most ample (and reasonably priced) sort of tourmaline, and it is crammed with iron, leading to its wealthy, darkish coloration.
And as Ashley Leavy, founder and academic director of the Love and Mild College of Crystal Remedy tells mbg, black tourmaline is primarily present in Brazil and China, although it may also be present in Nigeria, Kenya, Madagascar, and extra.
“A number of iron-based minerals have this historic connection—and fashionable connection—with safety,” Leavy notes, including that true black tourmaline will all the time be opaque. “You should not actually be capable to see gentle via it. When you see any gentle passing via it, it is most likely a dry white tourmaline or a very, actually darkish inexperienced or perhaps a actually darkish blue tourmaline.”
