Dravite Dravite Dravite Dravite

Well terminated single Dravite crystal from a small recent find that produced these incredibly colored crystals. The termination has an intensely colored red/pink coloration. I understand there were only about 30 crystals found and this one has the best quality in terms of color and crystal form, with many showing varying degrees of surface etching and pitting. This crystal has smooth crystal faces and flat, smooth termination faces with relatively minor amounts of etching.
