Huge! 103ct all natural uncut black Tourmaline

This is a great piece. Sourced from Brazil, this natural growth tourmaline still has pieces of its matrix, and even unpolished it has a glossy luster. The rich black hue of this gem is rich and full, and it measures 25mm x 20mm x 15mm. Whether used for cutting, or as an impressive display, this tourmaline won't disappoint. Untreated!
