Description

An aesthetic selenite from this lesser known German locality. This specimen has a central doubly terminated twinned crystal with a fan shaped array of smaller crystals at one end.

I would imagine this was originally purchased in the 1980s by Eddie Rohlach remaining in his collection until recently. There is no damage.
