Uvite is a tourmaline variety that forms elongated, columnar to prismatic crystals with a vitreous luster. The color range includes greens and greens of varying intensities, often displaying pleochroism, and crystals may show zoning along their length. Specimens from classic tourmaline localities are prized for clear to translucent color and well-formed terminations, frequently occurring in granular, schistose, or pegmatitic settings.

Collectors seek uvite for its typical crystal habit, size potential, and the association with other tourmaline varieties; notable sources include Brazil, the United States, Myanmar, Pakistan, and Tanzania. These crystals can exhibit attractive color zoning and even parallel growth, yielding aesthetically pleasing, sleeve-like prisms. The combination of color, luster, and classic tourmaline habit makes uvite a desirable target for motivated collectors building a tourmaline-focused cabinet or seeking representative examples from prominent mining districts.
