White Calcite Rhombohedral Cluster – Lanwen Mine, Yunnan, China

Discover the intricate details of this crystallized stone from the famed Lanwen Mine in Yunnan, China. Its complex structure and shimmering surface make it a stunning addition to any collection. Perfect for enthusiasts and collectors looking for unique mineral specimens.

This specimen is a naturally formed calcite sculpture exhibiting the trigonal crystal system, characterized by its rhombohedral cleavage and distinctive crystal habits. With a Mohs hardness of 3, calcite is relatively soft yet durable enough for careful display. The mineral's chemical formula, CaCO₃, reflects its composition as calcium carbonate. The piece displays a translucent to transparent quality with a vitreous luster that accentuates its crystallized surfaces, capturing light beautifully and highlighting its intricate form.

Originating from the Lanwen Mine in Yunnan province, a region well-regarded for its diverse and high-quality mineral specimens, this piece carries notable geological provenance. The mine's unique environmental conditions contribute to the formation of such detailed and well-defined calcite crystals.

Weighing 225 grams, this specimen’s sizable and complex crystallization makes it a significant display item. Its rarity lies in the combination of its natural sculptural form and the clarity of its crystals, making it a valuable addition for collectors who appreciate geological artistry and natural mineral growth.

To preserve its appearance, handle the specimen with care to avoid scratching or chipping due to calcite’s relative softness. Avoid exposure to acidic substances or prolonged moisture to maintain its natural luster and structural integrity.
