A very beautiful example of green fluorite on a matrix covered in small, clear quartz crystals. The piece is very clean of damage, with only the expected rubs at the extreme edges of the specimen.
The color of these pieces varies strongly with lighting-- under incandescent light they look grayish and undersaturated. To be best appreciated, they need the equivalent of indirect sunlight. What is depicted in the pictures is what you would see if the piece were placed next to a window on a cloudy day.
