Rough Tourmaline in Quartz from Brazil. Black Tourmaline is also called Schorl, and accounts for the majority of all natural tourmaline. Its prismatic, vertically striated crystals may be long and slender, or thick and columnar. These crystals are dispersed throughout the quartz in scattered, random arrangements. 

Size varies from 1/4 lb pieces to 10+ lbs. Please specify in your order notes any preference on individual piece size.
