Earth-mined Tanzanian tanzanite weighing 38.36ct ETW in a cushion cut, featuring heavily included clarity, heat treatment, and impressive dimensions.

Tanzanite is the blue-to-violet variety of zoisite, prized for its distinctive coloration and remarkable pleochroism. Depending on crystal orientation and lighting, tanzanite can display different blue, violet, and occasionally reddish or brownish tones.

Found commercially in the 1960s, tanzanite is sourced from a small mining region near Mount Kilimanjaro in northern Tanzania. Its limited geographic occurrence makes it particularly interesting to gemstone collectors.

This gemstone has undergone heat treatment, a widely accepted practice used to enhance tanzanite's desirable blue and violet coloration. Its heavily included clarity indicates prominent natural internal characteristics that may affect transparency and brilliance.

At 38.36 carats and measuring 18.8 x 18.8 x 10.6 mm, this tanzanite offers exceptional visual presence. Its substantial cushion shape makes it especially suitable for a custom statement pendant, collector's display, or one-of-a-kind jewelry creation.

Tanzanite has a Mohs hardness of approximately 6 to 7 and possesses perfect cleavage in one direction. Protective settings and careful handling are recommended, particularly for a heavily included specimen of this size.

This individual Tanzanian tanzanite combines impressive carat weight, classic cushion-cut styling, and distinctive natural inclusions in a substantial collectible gemstone.
