Fluorite with Calcite

This lovely miniature Fluorite with Calcite is from the Fairy Holes Pocket at the Lady Annabella mine, in Weardale, England, formerly known as the Blue Circle Cement Quarry and Eastgate Quarry, the Lady Annabella operation commenced in July 2020 and this Fairy Holes specimen was mined in this first year.  Deep sea-green cubic Fluorite crystals averaging 0.8 to 1 cm on edge emerge from an enveloping surrounding layer of creamy-white micro-crystalline drusy Calcite.  In direct daylight the Fluorite naturally fluoresces bluish green and under LWUV the crystals fluoresce bright lavender to lilac-mauve.  The Calcite does not fluoresce.
