Black Tourmaline or Schorl Tourmaline is part of the Boron Silica family of minerals. Tourmaline crystals are found in granite and granite pegmatites which are magma bodies deposited close the earth’s crust and eventually uncovered through surface erosion or continental uplift. The black color is a result of high sodium-iron concentrations during crystallization.


The larger crystals are a telltale sign of slow crystallization, meaning the temperature in the magma decreased very slowly giving more time for tourmaline to crystallize out. 


On a metaphysical level, it promotes a sense of power and self-confidence, allowing for a clearer, more objective view of the world.


This black tourmaline is such a fascinating piece because it has a deep, dark color to it that stands out among the light color of the granite. This piece is so full of contrast it really makes a statement.
