Fascinating mineral specimen from the Erongo Mountains in Namibia with an impressive combination of black Schorl Tourmaline, beige Orthoclase, and Hyalite Opal. The tourmaline crystals show a partially symmetrical growth form, which makes this specimen particularly attractive. A real highlight are the hyalite crystals, which fluoresce in bright neon yellow under UV light. A compact collector's specimen with excellent mineral diversity!
