{"product_id":"baryte-on-witherite","title":"BARYTE on WITHERITE","description":"Settlingstones mine was originally a lead mine, but for its final fifty years worked an extremely large vein of the relatively rare barium mineral Witherite, barium carbonate.  This fine cabinet display specimen is a beautifully crisp and clean example of snow-white Baryte crystals overgrowing a matrix of almost pure Witherite.  The Witherite is crystallised over the display surface and can be distinguished from the Baryte by its smaller crystal size and creamy, slightly off-pure white colour.  The Baryte forms straight edged spear-like tabular crystals of typically 0.7 cm tall by up to 1.2 cm wide at their bases.  A most aesthetic specimen dominated by an 8 cm diameter dome of Baryte covering Witherite.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780735836495,"sku":"CC13149","price":222.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC13149_d11a1069-e527-4a84-bf9f-c79227fc91ea.jpg?v=1783969977","url":"https:\/\/crystalclassics.co.uk\/products\/baryte-on-witherite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
