About this specimen

Nothing about this piece looks like a crystal at first: it is a mass of rounded knobs and ridges, cream-white where the surface is freshest and caramel-tan where iron has stained it, piled into something between coral and cauliflower. Turn it and the lobes catch the light in soft, chalky highlights — the botryoidal habit Guizhou collectors call popcorn gypsum.

Botryoidal growth happens when crystallisation begins at many points on a surface at once and each centre expands outward as a sphere until the spheres meet. Inside, the gypsum is still fibrous and radial; the globes are simply where the fibres ran out of room. Gypsum is CaSO4·2H2O at Mohs 2 — soft enough to mark with a fingernail, and happiest kept away from damp.

The mass measures 5.1 × 4.8 × 3.3 cm and weighs 54 g, presented on the clear acrylic cube in the pictures. What is pictured is what leaves the shop.
