About this specimen

Cream-white dolomite covers most of this Inner Mongolia piece in tight rounded nodules, a bed of popcorn with rust-brown iron staining settled into every crease between them. The interest sits at one end, where the crust runs out: two plum-purple fluorite cubes, translucent and sharply squared off, set directly into the dark green-grey host rock, with small brassy grains of pyrite scattered through the darker ground beside them.

Dolomite, CaMg(CO3)2, takes this globular form when it precipitates quickly onto a rock wall instead of growing as free rhombs, and the brown in the hollows is iron oxide left behind by later groundwater. The fluorite is the harder of the two at Mohs 4 against the carbonate’s 3.5, though neither will forgive a knock. What carries the piece is the colour run: warm cream against cold violet against near-black rock, all within a few centimetres.

The specimen weighs 50 g and sits comfortably in one hand, unmounted and shot against a plain grey ground. The piece in these frames is the one that ships.
