Tourmaline var. Schorl Cluster (Black Tourmaline)
The early history of the mineral schorl shows that the name was in use prior to 1400 AD named after a village known today as Zschorlau in Saxony, Germany. The present specimen consists of very large intersecting trigonal crystals, measuring up to 9.5cm along the edge, with well-defined pyramidal terminations and classically striated faces. Many intergrown crystals are visible on the obverse as well as some light brown matrix. A highly aesthetic and dramatic, room-sized specimen.
Measures 8 ½ x 8 x 3 in
