This fine miniature features a single Bournonite crystal, 1.7 cm long by 1 cm thick, sat in the centre of a Quartz matrix encrusted all round with micro-crystals of Quartz.  There is also a rich coverage of sooty black micro-tetrahedral Freibergite crystals with tiny Pyrite crystals sparsely scattered all over.  The Bournonite crystal forms an excellent cogwheel habit of steel-grey with a bright metallic lustre.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584158716079,"sku":"CC20000","price":350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC20000.png?v=1771845632","url":"https:\/\/crystalclassics.com\/products\/bournonite-with-freibergite-and-pyrite-on-quartz","provider":"Crystal Classics","version":"1.0","type":"link"}
