Cubic Dolomite Specimen, Guangxi, China

Marvel at the striking cubic formations of dolomite, exhibiting a mesmerizing vitreous luster, sourced from the renowned Dachang Mine in Nandan, Guangxi, China. This exquisite mineral specimen is a must-have for collectors, offering a unique glimpse into the natural beauty and geological wonders of this region.

Dolomite (CaMg(CO₃)₂) crystallizes in the trigonal-rhombohedral system, but this specimen is notable for its rare, well-defined cubic crystal habit, a form that is less commonly observed and highly valued among mineral enthusiasts. The crystals display a translucent to transparent quality with a soft pink to pale salmon hue, which is characteristic of the dolomite from this locality. Its vitreous luster enhances the visual appeal, reflecting light elegantly across the smooth crystal faces.

The Dachang Mine in Guangxi is a significant source of mineral specimens prized for their clarity and form, making this piece a representative example of the region’s unique geology. Dolomite ranks 3.5 to 4 on the Mohs hardness scale, requiring careful handling to avoid scratches or damage. Its rarity in this cubic morphology adds to its collector value, making it an excellent display specimen for those interested in crystallography and regional mineralogy.

To preserve its vitreous shine and delicate crystal edges, it is recommended to handle this specimen with clean hands or gloves and to avoid exposure to harsh chemicals or prolonged direct sunlight.

China — dominant modern source for collector-grade specimens since the 1990s.
