Scheelite Crystal, Xuebaoding Mountain, Sichuan

Scheelite crystals from Xuebaoding Mountain in Sichuan, China, are highly regarded for their distinctive cubic crystal system and lustrous appearance. This specimen features the characteristic well-formed cubic crystals of scheelite, a calcium tungstate mineral with the chemical formula CaWO₄. Exhibiting a vitreous to adamantine luster, the crystals often present a translucent to transparent quality, with a subtle range of colors from pale yellow to honey-hued tones, typical of this locality.

With a Mohs hardness of 4.5 to 5, scheelite is moderately durable but should be handled with care to preserve its sharp crystal edges and smooth surfaces. The Xuebaoding mine is renowned for producing some of the finest scheelite specimens globally, prized by collectors for their clarity and well-defined geometric forms.

This cabinet-sized specimen offers an impressive display piece with its sizable cubic crystals, making it a valuable addition for those interested in crystallography and mineralogy. Its provenance from a notable Chinese mining region adds to its collectible appeal, representing a mineralogical treasure from a unique geological environment.

For optimal preservation, it is recommended to avoid prolonged exposure to direct sunlight and moisture, as these can affect the crystal's luster and structural integrity over time.
