{"product_id":"calcite-212","title":"CALCITE","description":"A classic Calcite, also known as the variety Sand Calcite, from the famous Fontainebleau quarries at Seine-et-Marne, Ile-de-France, France, about 60 km to the south-southeast of Paris. The Calcite has developed in spiralling circles of overlapping, offset stacked rhombic crystals, each with a fine sucrosic sandy texture with the feel of fine sandpaper.  The overall structure is that of a rose with many layers of petals.  The specimen has been damaged in three areas, excluding its point of attachment, but these allow the internal structure and mineralogy to be studied.  A great Fontainebleau Calcite.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781149466959,"sku":"CC21884","price":333.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC21884_d1426124-fe0c-42eb-9ea4-2c56b28302cd.jpg?v=1783979731","url":"https:\/\/crystalclassics.co.uk\/products\/calcite-212","provider":"Crystal Classics UK","version":"1.0","type":"link"}
