{"product_id":"phenakite","title":"PHENAKITE","description":"The Tangen Feldspar mine is situated on the southern Norwegian coast at Kragerø in Vestfold og Telemark.  It was a Quartz and Feldspar mine which worked a amphibolite hosted pegmatite on the western slope of Mount Sjåen.  This site sill exists but collecting is forbidden by its owner.  Although the mine recorded only twenty-six mineral species (not bad really!), many of these were very rare, making it a fascinating site.  Its best-known species is Phenakite, the rare beryllium silicate, which occurs here as dark greyish-green crystals, an unusual colour for the species.  This large miniature is a fine example displaying a terminated 3.4 x 2.1 x 1.9 cm Phenakite crystal standing vertically out from a matrix of cryptocrystalline opaque milky Quartz.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545423499439,"sku":"CC28769","price":1750.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC28769.png?v=1770390290","url":"https:\/\/crystalclassics.com\/products\/phenakite","provider":"Crystal Classics","version":"1.0","type":"link"}
