Schorl (Black Tourmaline) – Namibia

This schorl (black tourmaline) specimen from Namibia measures 12.5 × 6.5 cm and weighs 425 g. Well-formed black crystals rise with a deep, lustrous surface and sharply defined terminations, their vertical growth creating a strong, sculptural silhouette. Schorl is the iron-rich, most common member of the tourmaline group, and Namibia's pegmatite deposits are known for producing large, well-terminated crystals like this one. Its dark, matte-to-glossy color makes it a striking contrast piece next to lighter minerals in a collection.
