{"product_id":"pyrite-with-calcite","title":"PYRITE with CALCITE","description":"This miniature is a particularly fine example of well crystallised Pyrite from the long since closed Blackdene Mine, County Durham.  Famous for its very fine Fluorite, Blackdene also produced a limited number of other species.  Bright, metallic brassy-yellow Pyrite has developed as cubic and elongated crystals, all with stepped crystal growth across the faces measuring to 7 mm.  Intermixed amongst the crystals is milky-white Calcite, forming occasional small crystals to about 7 mm across.
