About this specimen

Colourless gypsum needles burst out of an olive-brown crust in a dozen small starbursts — some splayed flat against the rock like snowflakes, others standing free as long single blades. Every needle is glassy and transparent, with a pearly sheen where a cleavage plane catches the light, and the dark olive matrix behind them makes the clear crystals read almost silver.

Gypsum is calcium sulphate dihydrate, CaSO4·2H2O, and at Mohs 2 it is the softest thing most collectors keep: a fingernail marks it, and standing water will slowly take it into solution. Sprays like these grow where sulphate-rich water seeps through a cavity at a crawl, each rosette starting from a single seed on the wall. Store it dry and well away from anything harder.

The cluster is 7.4 × 3.8 × 3.3 cm and 75 g, light for its bulk as gypsum always is, and shown unmounted in the hand. Nothing here is a representative sample: this is the cluster itself.
