Fluorite With Calcite, Blackdene Mine, Weardale, County Durham, United Kingdom
ex. Walter Rieger collection, 1978
Size: 11.8 × 8.7 × 6.8 cm
Very seldom seen fluorite from the UK. Bright pink fluorescent calcite crystals on a big blue fluorite crystal edge (almost 12 cm). The color changes with the lighting. The fluorite appeared grayish blue under artificial light. Strong, almost dark indigo blue under daylight.
Minor edge wears on a few calcite crystals and little chipping on the fluorite crystal tip. Still a fantastic specimen for the locality.
