Rare Tetrahedral Genthelvite — Huanggang Mine, Inner Mongolia (271g)

A masterclass in rare mineral geometry. This 271g specimen features sharp, well-defined crystals of Genthelvite—a rare zinc beryllium sulfur silicate—from the world-renowned Huanggang Deposit. We curated this piece for its exceptional tetrahedral crystal habit, a hallmark of the species that is rarely executed with such precision. Anchored by a matrix of Quartz and Calcite, the Genthelvite crystals exhibit a sophisticated earthy-rose to cocoa palette and a distinct, waxy-to-vitreous luster. This is a high-pedigree specimen for the collector who values mineralogical rarity and the striking mathematical beauty of Inner Mongolian finds.
