About this specimen

A group of cassiterite crystals lies across the middle of this upright fluorite, brown-black and greasy in lustre, the blades meeting at an angle in the elbow-like arrangement the species so often takes. A second cassiterite, sharper and nearer to black, is set into the fluorite higher up on the right. The host itself is pale lilac, cloudier through the base and clearing to a faint blue-green at the summit.

Cassiterite (SnO2) is tin ore, and at Yaogangxian it grew with the fluorite in the same tin and tungsten veins rather than being dropped onto it afterwards — the crystals are locked into the fluorite surface, not perched on it. At Mohs 6 to 7 it is considerably harder than its host, and its density, close to seven times water, gives even a small piece like this an unexpected heft in the hand.

The specimen stands 6.6 × 3.8 × 2.8 cm and weighs 80 g, mounted with putty on a clear acrylic block for upright display. The specimen shown is the one you receive.
