Descripción

Locality: Morocco

Approximate size: 36.5 x 21 cm (14.5 x 8.5 in)

This one-of-a-kind selenite log from Morocco is a heavy, block-shaped length of natural selenite, its long fibrous crystals running end to end like the grain in a piece of timber. The faces are a soft, glassy white with a silky sheen where the light runs along the crystal lines, while the outer edges carry a creamy, sandy rind left from the rock it grew in. Left raw and unpolished, it has the look of a freshly split log of ice and makes a striking floor or shelf piece.

Sold as selenite, this is the fibrous satin-spar form of gypsum. It grows slowly from mineral-rich water as it evaporates, and in Morocco large masses of it formed in old evaporite beds, where tightly packed parallel crystals built up into thick seams that are quarried out in blocks like this one. The name comes from the Greek for moon, after its soft, pearly glow.

At 1.5–2 on the Mohs scale, selenite can be scratched with a fingernail and dissolves slowly in water, so keep this piece dry and dust it with a soft cloth or brush.
