We are pleased to have found an old cache of classic Red River Floodway specimens of Gypsum crystal specimens. The specimens we have came from a find made 20 years ago in Canada. This specimen depicts several gemmy well formed fish-tail twins of Selenite radiating outward from a central cluster of crystal of Gypsum. Fish-tail twins crystals measure to 3cm with excellent sharp terminations, and are gemmy slightly tinted yellow. A fine specimen from the find.
