Description:An impressive large cryolite specimen from the famous extinct Type Locality in Greenland. Massive white cryolite hosts typical accessories of cleavages of brown siderite rhombs and bright golden chalcopyrite, especially on the striking back side.

A large, rich and highly representative example of this rare species in combination. Old material, mostly from the 1800s and early 1900s. Modest interesting peach-colored fluorescence. Ex David Burgess Collection, for whom Burgessite is named. 5.7 pounds or 2.6 kilos mass.
