Ussingite (rare silicate - Type Locality) and Sodalite (both fluorescent) Allred Coll.

Item Description

Ussingite is a rare silicate found in syenite pegmatites, also sodalite-bearing xenoliths. Greenland is the Type Locality for this species. The large specimen features pods and stringers of translucent, pretty lavender ussingite surrounded by off-white sodalite and matrix. The sodalite fluoresceses bright yellow and the ussingite a moderate green, which is hard to see in the photos. Very seldom available combination material. Ex Jonathon Allred Fluorescent Collection.
