{"product_id":"calcite-with-native-copper-inclusions-1","title":"CALCITE with NATIVE COPPER Inclusions","description":"An absolutely delightful example of classic Calcite included with Native Copper from Franklin mine, at Franklin in Houghton County, Michigan, USA.  An entire scalenohedral crystal, 7 cm tall, with parallel prism faces and a termination divided into three individual peaks, is uniformly coloured a deep flesh-pink by finely disseminated Native Copper inclusions. Adding interest and variety is a relatively colourless and transparent zone in one of the three terminated tips which extends downwards by 3 cm towards the main prism.  Emerging from the Calcite crystal at numerous points are hackly granules and small sheets of Native Copper, slightly tarnished to a dull copper-red.  Note, the three tips are slightly bruised, but this is not apparent unless examined very closely.  A splendid specimen and example of Native Copper included in Calcite from Upper Michigan. This specimen is accompanied with its own custom-made clear acrylic base, with contour-milled recess.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46545177116847,"sku":"CC20251","price":7500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC20251.png?v=1770375929","url":"https:\/\/crystalclassics.com\/products\/calcite-with-native-copper-inclusions-1","provider":"Crystal Classics","version":"1.0","type":"link"}
