{"product_id":"calcite-with-pyrite-3","title":"CALCITE   with PYRITE","description":"This superb miniature Calcite from the P?'bram Mining District in the Czech Republic, composed of multiple generations of mineral deposition, each phase manifesting as a different habit, colour, and lustre.  Formed around a central core of granular sooty-black sulphides or Mg\/Mn minerals, the first phase of calcite forms scalenohedral 'dog-tooth' crystals to over 2 cm tall that radiate outward hedgehog-like fashion.  These have then been coated in dull brick-red Calcite micro-crystals with a matt lustre then followed by burnt candy-red lustrous Calcite crystals, all approximately 1 mm in length and aligned epitaxially to the scalenohedral major axis.  A little Pyrite is also attached.  A beautiful and fascinating Calcite from P?'bram.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545169055919,"sku":"CC19696","price":2500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC19696.png?v=1770375419","url":"https:\/\/crystalclassics.com\/products\/calcite-with-pyrite-3","provider":"Crystal Classics","version":"1.0","type":"link"}
