||Fluorite - penetration twins, early specimen
Weardale North Pennines
County Durham, England
4.9 x 4.7 x 3.2 CM (miniature)
Brilliant green transparent cubes to 4 CM across show penetrations and fine growth hillocks. This also has a very nice daylight Fluorescence in vivid purple blue. A quite old specimen (pre 1950's) that is notably different from any of the recent finds. The color and clarity stand out in person, but are hard to see in photos. The condition is fine on the two primary display sides, the back is broken where it was removed and not visible in any logical display.
