{"product_id":"cassiterite-and-fluorite-on-zinnwaldite","title":"CASSITERITE and FLUORITE on ZINNWALDITE","description":"Interlocking platy 'books' of micaceous Zinnwaldite crystals with an extensive unidentified orange coating form the matrix hosting a cluster of dark grey to black intergrown, somewhat pyramidal, Cassiterite crystals, the largest crystal reaching 1 cm across. The Cassiterite displays an unusual matt, to silky surface lustre. Further, scattered, small (1 to 2 mm) cubic crystals of very dark purple Fluorite are also present. The main Cassiterite crystal is completely undamaged, but the others are either slightly chipped or,  in the case of a second grouping, has an edge missing where it is fractured. This is, nevertheless, a nice classic association of species from the famous Horní Slavkov (Schlaggenwald) area in Karlovy Vary Region, Bohemia, Czechia.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781013414223,"sku":"CC19101","price":259.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC19101_9f1d0e29-1833-4cda-ab31-de64c9248707.jpg?v=1783975607","url":"https:\/\/crystalclassics.co.uk\/products\/cassiterite-and-fluorite-on-zinnwaldite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
