Dravite is a green to brown variety of tourmaline with a typical elongated prism habit and a vitreous luster. It commonly forms in pegmatites and metamorphic rocks, often displaying rich green hues that range from olive to emerald, sometimes with zoning. High-quality crystals may exhibit well-defined parallel striations and occasional trapezohedral terminations, making them visually striking in hand samples and cabinet collections.

Noted localities include Tanzania, Brazil, Australia, Nepal and the USA, where dravite forms slender prisms and clusters within fine-grained schists or granite pegmatites. Some specimens show deep forest greens or yellowish greens, and platy or prismatic aggregates are prized by collectors for their clarity and color. The mineral’s association with other tourmalines and with tourmaline-bearing pegmatites adds to its appeal for locality-based collecting.
Collectors value dravite for its distinct color range within tourmaline species, its transparent to translucent appearance, and the variety of crystal habits it can display. Well-formed crystals from notable localities are sought after for display and study, contributing to its status among tourmaline enthusiasts and mineral collectors alike.
