What is Black Tourmaline?

Black tourmaline is schorl, the most common member of the tourmaline group. It grows as long prisms with distinctive parallel grooves (striations) and a rounded triangular cross-section, typically in granite pegmatites.

Tourmaline is piezoelectric and pyroelectric – squeezing or warming a crystal creates an electrical charge. Dutch traders in the 1700s used heated tourmaline to pull ash from their pipes, calling it aschentrekker. The name comes from the Sinhalese turamali.

Pair Black Tourmaline with a protection & cleansing ritual

A traditional cleansing ritual for resetting your space and feeling protected.

Traditionally paired with: White sage or palo santo smudge sticks · Dragon's blood, frankincense or myrrh incense · A white or black candle

  • Open a window, then light a white sage or palo santo stick and let it smoulder.
  • Gently waft the smoke around your crystal and through the room, corners first.
  • Light a white candle and place your crystal beside it while you set a simple intention, such as "This space is calm and protected".

Safety: never leave candles, incense or smudge sticks burning unattended, keep them away from children, pets and anything flammable, and ventilate the room. Rituals are shared as tradition, not as a treatment.
