Huge! 136.50ct all natural uncut black Tourmaline

This is a great piece. Sourced from Brazil, this natural growth tourmaline still has pieces of its mica matrix, and even unpolished it has a glossy luster. The rich black hue of this gem is rich and full, and it measures 53.2mm x 32.4mm x 13mm. Whether used for cutting, or as an impressive display, this tourmaline won't disappoint. Untreated!
