Description

Authentic Tanzanite Crystal Specimen from Tanzania

This Tanzanite specimen is sourced from the Merelani Hills of northern Tanzania, the only known source of natural Tanzanite in the world. The piece showcases its signature blue to violet hues, with a natural crystal formation that highlights the mineral’s unique geometry and aesthetic appeal. Each specimen is carefully selected to display vibrant coloration and well-defined crystal faces.

Geological Formation
Tanzanite is a variety of zoisite, a calcium aluminum silicate mineral that forms under high-temperature and high-pressure conditions during regional metamorphism. The crystals grow within thin seams of metamorphic rock, often alongside other minerals such as garnet and quartz. The distinctive blue-violet coloration comes from vanadium substitution in the crystal lattice. Its formation conditions are extremely rare, making Tanzanite highly prized among mineral collectors.

Collector Value
Natural Tanzanite crystal specimens are highly sought after due to their striking color, rarity, and crystal formation. The specimens in crystal form are particularly valuable for collectors because they exhibit natural growth patterns, well-defined crystal faces, and exceptional transparency. Each 1.2 gram piece is a compact but visually captivating addition to any mineral collection.

Uses & Display
Ideal for collectors, display cases, or educational collections, this Tanzanite crystal specimen can be showcased individually or as part of a curated mineral assemblage. Its natural crystal formation ensures that each piece has a unique aesthetic appeal, highlighting the intricacy of mineral growth in nature.

Care & Handling
Tanzanite is relatively delicate with a Mohs hardness of 6–7; handle specimens carefully to avoid scratches or chips. Avoid exposure to harsh chemicals and clean gently with a soft cloth to preserve its natural luster and crystal faces.
