{"product_id":"allargentum-1","title":"ALLARGENTUM","description":"A very fine and relatively rare specimen of the silver antimonide mineral, Allargentum from the Schlema-Hartenstein District of Saxony, Germany.  A 3 x 2 cm grey-green schist-like matrix forms the base of a much larger crystallised specimen of pale white-silvery-golden Allargentum that has developed as a heavy and solid mass covered in a spongy, honeycomb cells and interconnected ridges.  A superb example of this uncommon and seldom seen species.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780364017999,"sku":"CC10130","price":1850.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC10130_059be20f-4186-437b-a745-4c8589049b34.jpg?v=1783967889","url":"https:\/\/crystalclassics.co.uk\/products\/allargentum-1","provider":"Crystal Classics UK","version":"1.0","type":"link"}
