Fluorite

This lovely small miniature is from The Bull Vein at the Lady Annabella mine at Eastgate. A compact cluster of intergrown and interpenetrant mid-sherry Fluorite crystals of good outer transparency grading to translucent and then, opaque creamy-white cores.  The crystals have wonderfully sharp, clean-cut edges, smooth faces and a bright to slightly resinous lustre.  In direct daylight the colour intensifies to a strong sherry-tan with more hints of yellow, although does not fluoresce.
