A dramatic black Tourmaline (Schorl) cluster from the Erongo Mountains of Namibia, composed of radiating sprays of lustrous prismatic crystals accented by sparkling aggregates of Muscovite Mica. The specimen displays exceptional texture and contrast, with jet-black Tourmaline crystals emerging in dense, starburst-like formations from a matrix dusted with pale silvery-brown Mica.
The Tourmaline crystals exhibit the characteristic elongated habit and strong longitudinal striations typical of Schorl. Their radial arrangement suggests growth into open cavities, where individual crystals were free to develop outward in multiple directions. Fine Muscovite occurs as platy crystalline aggregates coating portions of the specimen, reflecting light and providing a striking visual counterpoint to the darker Tourmaline.
This assemblage formed within the famous Erongo Pegmatite system, a complex network of granitic Pegmatites and hydrothermal cavities created during the final stages of magmatic crystallisation. Boron-rich fluids promoted the growth of Tourmaline, while Potassium-rich residual fluids later deposited Muscovite within the same cavities. The result is a highly aesthetic specimen that captures the dynamic mineral-forming processes of one of Africa's most celebrated mineral localities, renowned for producing world-class pegmatite minerals and crystal clusters.
Mounted on a bespoke stand.
