The specimen is dominated by a 7.8 x 5.4 x 5.2 cm, transparent to translucent, colourless to light grey Quartz crystal with a perfect termination. Two and a half faces of the Quartz prism are encrusted with honeycomb-like, crystallised, snow white Dolomite and around the base are rich micro-druses of white Quartz plus crystals of Pyrite (more likely Chalcopyrite) and Sphalerite. A superb, 2.2 cm wide silver Arsenopyrite crystal is also present. The base reveals a mixture of green and purple Fluorite. A super combination from Yaogangxian mine, China.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781237907791,"sku":"CC32122","price":250.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC32122.jpg?v=1779756593","url":"https:\/\/crystalclassics.co.uk\/products\/quartz-with-arsenopyrite-dolomite-sphalerite-and-pyrite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
