This exceptional specimen features a lustrous tanzanite crystal artfully perched on a matrix of crystalline calcite, sourced from the renowned Merelani Hills in the Lelatema Mountains, Simanjiro District, Manyara Region, Tanzania. The tanzanite crystal measures 3.5 x 1.7 x 1.5 cm, exhibiting a natural, untreated color transition from deep blue to violet, culminating in a gem-quality termination. The juxtaposition of the vibrant tanzanite against the contrasting calcite matrix not only enhances its visual appeal but also underscores its rarity, as matrix specimens of this caliber are seldom encountered.

Tanzanite, a blue-violet variety of the mineral zoisite, owes its unique coloration to trace amounts of vanadium. Discovered in 1967, it is found exclusively in the Merelani Hills of Tanzania, making it a gemstone of both geological and geographical significance. The calcite matrix, a common carbonate mineral, provides a striking contrast, highlighting the tanzanite’s vibrant hues.

This specimen’s pristine condition, free from repairs or damage, combined with its aesthetic composition, makes it a true rarity and a valuable addition to any discerning collection.
