About this specimen

Snow-white crust, dark grey host rock, and a sprinkling of brassy pyrite across the upper two thirds — this Tonglushan plate works entirely on contrast. The pyrite crystals are discrete and blocky, a few millimetres each, sitting on top of the calcite coating rather than growing through it, and their olive-gold tarnish keeps them modest rather than mirror-bright. At centre right a small fan of bladed white calcite interrupts the crust, and the raw dark rock breaks out along the right edge.

Tonglushan at Daye, Hubei is a copper-iron skarn, and pyrite scattered on a late calcite blanket is one of its characteristic looks. Pyrite is FeS2 at Mohs 6 to 6.5 while the calcite around it is only Mohs 3, so the crust is the vulnerable part; keep the plate dry, since damp storage is what eventually breaks sulphides down.

The plate is 8.9 × 1.8 × 5.6 cm and weighs 79 g, thin enough to sit flat in a drawer and shown here in hand without a base. The specimen in these photographs is the one that will be wrapped for you.
