Crushed Black Tourmaline Chips (Grade A+) from Brazil, Pea-Sized Gravel (2mm-4mm) for Woodworking Inlay, Resin Art, Embellishments or Orgone Pyramids

Tourmaline is not a single mineral, but a large family of closely related minerals known for their unusual optical and physical characteristics. It is chemically more complex than most minerals and displays an exceptional range of colors and varieties, though black tourmaline is the most abundant.

This high-quality crushed black tourmaline, sourced from Brazil, has a striking natural luster. The material is exceptionally clean and free from contamination by other minerals or host rock. Tourmaline is also one of the official birthstones for October.
