Beschreibung

Locality: Morocco

Metric: Height 43 cm · Width 25.5 cm · Depth ?

Imperial: Height 17 in · Width 10 in · Depth ?

This one-of-a-kind selenite log from Morocco is a tall, heavy column of raw selenite, its fibrous crystals running in long parallel ridges from top to bottom. The sides glow a soft, translucent white with a silky sheen, streaked with cream and tan where the old host rock still clings, and the top is capped with a rough, peach-toned crust. Stood upright, it reads like a pillar of ice and makes a striking floor 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 about 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.
