{"product_id":"calcite-48","title":"CALCITE","description":"It really is quite amazing how the colour and habit of Calcite can vary, especially throughout a single mine such as Tsumeb.  However, we all know Tsumeb is exceedingly special and hence its variety of specimen-grade Calcites does appear never-ending.  This cabinet-size specimen is richly covered with magnificent, highly distorted rhombic Calcite crystals of opaque, pure clotted-cream-white which form steep-sided prisms with occasional triangular faces.  These crystals attain 3.3 cm on edge.  Smaller rhombic crystals are sometimes developed along the edges of the larger crystals giving a sawtooth profile.  The large crystals are scattered over a massive Calcite matrix, itself encrusted with micro-Calcite crystals to about 1 mm.  A delightful specimen.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780515471695,"sku":"CC12112","price":1480.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC12112_13076956-c1f1-49cd-8313-b94f55694b85.jpg?v=1783969164","url":"https:\/\/crystalclassics.co.uk\/products\/calcite-48","provider":"Crystal Classics UK","version":"1.0","type":"link"}
