Gem fishtail-twinned Gypsum ex. Mullane Coll.

Item Description

A striking, highly unusual, water-clear, colorless and doubly terminated hourglass twinned gypsum crystal from the famous Lake Gilles of South Australia, Australia. The floater crystal is strikingly included with funnel-shaped clay particles and one termination is a fishtail-twin. Lake Gilles produces some of the most unusual gypsum crystal forms in the world. Essentially pristine, with only the most trivial of edge wear. Most certainly a strange-looking specimen! It looks carved! See the Mineralogical Record article in the May-June, 1982 issue, Vol. 13, No. 3. Ex Mullane Collection. Older material.
