Fluorite, Wolframite, Calcite and Quartz. Yaogangxian Mine, Hunan, China. Two generations of Fluorite, the first a blue-grey, lightly etched octahedral habit capped off with perfectly clear, color zoned cubic crystals. Excellent LW-UV fluorescence that contrasts perfectly with the jet-black Wolframite. Quartz scepters and a light edging of Calcite complete a fantastically compelling small cabinet plate. 2.25" x 1.5" x .75", 43 gms.
