{"product_id":"wurtzite-with-galena-sphalerite-and-quartz","title":"WURTZITE with GALENA   SPHALERITE and QUARTZ","description":"This rich combination of species is built up from an underlying core of massive Sphalerite capped with a 1 cm thick layer of Galena. The Galena’s surface is covered with bright silver Galena crystals with a 'melted-look', producing smooth, rounded crystals, some showing etched contour lines about their circumference. The Galena has a dazzling metallic lustre causing the specimen to glitter. Amongst these are equant black Sphalerite crystals, faces of which commonly have a golden-yellow to greenish-yellow translucency. Overgrowing much of the Galena and Sphalerite are druses of micro-crystalline Quartz, itself coated in even finer microcrystals of reddish-brown Wurtzite. The Wurtzite forms a pervasive, granular drusy crust which obscures probably seventy percent of the Galena. An excellent specimen from the Příbram mining district in the Czech Republic.\n","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545169973423,"sku":"CC19754","price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC19754.png?v=1770375477","url":"https:\/\/crystalclassics.com\/products\/wurtzite-with-galena-sphalerite-and-quartz","provider":"Crystal Classics","version":"1.0","type":"link"}
