Black tourmaline (schorl) is a deep-black silicate, hard (7 to 7.5 on the Mohs scale), which tradition links to protection and grounding. Robust, it suits daily wear. Here's what it really is, what tradition says, and how to choose it.
Black tourmaline, or schorl, is a complex silicate (boron and aluminium) that is very common. It often appears as crystals striated lengthwise, in a dense black. Its hardness (7 to 7.5 on the Mohs scale) is high: it resists scratches well and suits bracelets and rings.
In crystal tradition, black tourmaline is one of the great stones of protection and grounding: it is said to absorb negative energies. These virtues are traditions and beliefs: they are not scientifically demonstrated and replace no medical advice (see sources).
Hard and affordable, black tourmaline is easy to wear daily, including as a bracelet. Rough striated crystals are typical and reassuring on authenticity. Beware black glass or resin sold as tourmaline. See our natural stone bracelet guide.
Lukewarm water and a soft cloth. Black tourmaline is robust, but still avoid aggressive chemicals.
