About this specimen

Khaki and olive-green blades interlock across the whole face of this Guizhou piece, each one lens-shaped and slightly curved, packed as tightly as fallen leaves. Between them, thin white dolomite blades catch the light and break up the green. The overall surface has a waxy, low sheen rather than a bright glassy one, and the appeal lies in the density of the intergrowth and in that unusual, almost military colour.

Siderite is FeCO3, the iron carbonate, more often met in warm chocolate browns; the greenish cast on these blades is what sets the specimen apart from the usual rhombs. Siderite runs Mohs 3.5–4.5 and the dolomite (CaMg(CO3)2) beside it 3.5–4, so both are soft carbonates that will fizz and etch on contact with acid. Cleaning means a dry brush and nothing stronger.

A long piece — 8.1 × 3.8 × 4.1 cm, 170 g — that lies best on its side in a case, and it comes without a stand. Each photograph here was taken of this exact piece, hand-held for scale.
