Baryte (uncommon Missouri) Bartels Coll.

Item Description

Water-clear, colorless, very glassy gem-like elongated barite crystals cover the mounded oxide-tinted barite matrix on this rare and impressive 360-degree miniature from this old barite mine, that closed in 1944. These were called "glass tiff" and many of the crystals are doubly terminated, reaching 9 mm. Choice material from a limited 1995 find. Ex Ted Bartels Collection.
