About this specimen

Amber-tan and entirely knobbly, this small Guizhou gypsum is a stack of coalesced lobes rather than one sphere — four or five rounded heads pressed together, the largest about a centimetre across. Every millimetre of the surface is sugared with minute pointed crystals that return light as a soft glitter rather than a shine, and the iron staining runs deeper in the creases where the lobes meet.

Gypsum (CaSO4·2H2O) is Mohs 2, soft enough for a fingernail to mark, and on a drusy piece like this the crystal tips are the first thing to suffer. Keep it dry as well as untouched: gypsum is slightly soluble in water, and washing a specimen of this habit rounds off precisely the texture that makes it worth looking at.

Small, at 3.3 × 2.5 × 2.3 cm and 20 g, mounted on putty on a clear acrylic cube. This is the specimen in the photographs, down to the last lobe.
