Description: Fluorite. 5.5 X 2.5 cm. "Blue Room, Blanchard Mine, Bingham, Socorro County, New Mexico. A collector could go up the hill and descend to this big room (the Blue Room), the walls of which were coated with these beautiful little blue fluorite crystals. Unfortunately, the fluorite from there is very light-sensitive, and will assume a dull, colourless aspect after only a few day (or less) in direct sunlight.. This specimen has never seen the light of day. Gift of Will Wilkinson, when he was a student at New Mexico Tech in 1970 or 1971.
