1.3" Gemmy Cassiterite Crystals with Quartz - China

This 1.3" wide specimen features an aggregation of translucent cassiterite crystals formed in association with quartz. It comes out of the Amo Sn deposit in Yunnan, China, a location know to produce exceptional cassiterite crystals. Their coffee brown coloration and natural striations make the lustrous faces pop when rotated beneath a light source.

It has been mounted to an acrylic display base with mineral tack.

About Cassiterite

Cassiterite is a dense, lustrous tin oxide mineral (SnO₂) best known as the world’s primary ore of tin and prized by collectors for its striking crystal forms. Typically appearing in shades of brown, black, or reddish-brown, cassiterite can also occur in beautiful honey-yellow to near-colorless crystals when impurities are low. Its exceptional hardness and high refractive index give well-formed crystals a brilliant, almost metallic sparkle, especially in twinned or pyramidal habits. Cassiterite commonly forms in hydrothermal veins, pegmatites, and alluvial placer deposits where its heavy, durable grains accumulate over time. Found in classic localities such as Bolivia, China, DR Congo, England, and Cornwall, this mineral holds both immense historical significance—fueling centuries of tin production.
