About this specimen

One snow-white puff of gypsum needles sits near the top edge of a thin iron-brown plate: a single hemispherical rosette built from hundreds of hair-fine crystals radiating out of a common root. The matrix repays a second look as well — chocolate and rust brown, with a silvery-grey botryoidal glaze spreading across the middle and a blade-like point at either end.

Gypsum is CaSO4·2H2O and sits at Mohs 2, the softest thing most collectors keep. A fingernail marks it and warm water begins to dissolve it, so a rosette like this one should never be rinsed; the needles mat together and lose the frosted texture that makes them worth having in the first place. Dust it with a dry, very soft brush or a puff of air, and keep fingertips off the white.

The plate spans 7.9 × 3.0 × 5.3 cm and weighs 75 g, presented on the clear acrylic block in the images, set on a dab of white putty. Photographed as received, this is the specimen offered.
