{"product_id":"calcite-320","title":"CALCITE","description":"This is a small, but historic individual Calcite crystal\/s from the famous Clausthal-Zellerfeld area in the Harz Mountains, Lower Saxony, Germany. Although small, this fascinating specimen shows two styles of Calcite crystal intergrown, but both presenting an unusual silky surface appearance. The first form, a three-sided cream-coloured pyramidal (but more likely a flattened rhomb) extends in two opposite directions through the specimen. Surrounding this, and extending out in the opposite direction to the first crystal is a white disc-like form of Calcite, much like a poker chip. There is a little damage in the form of light scratching around the sides, but this is a lovely old-time piece from this famous mining area. It is accompanied with a very old (probably mid-19th century) handwritten label stating \"Kalkspath Clausthal\".","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46792442118319,"sku":"CC29149","price":150.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC29149.png?v=1787057305","url":"https:\/\/crystalclassics.com\/products\/calcite-320","provider":"Crystal Classics","version":"1.0","type":"link"}
