{"product_id":"pyrargyrite-14","title":"PYRARGYRITE","description":"A magnificent specimen of the silver-antimony sulphosalt Pyrargyrite from the Catharina Neufang mine in the St. Andreasberg mining district of Lower Saxony, Germany.  Set against an off-white creamy matrix of Calcite and other metallic sulphosalts, the Pyrargyrite forms four clusters, two of which measure around 1 .0 to 1.2 cm in diameter.  These are linked by a smaller group to form a chain of stacked crystals across the specimen; one smaller 0.8 x 0.8 cm group sits separate on the micro-crystallised Calcite.  Individual Pyrargyrite crystals attain 5 mm across and all are black with a bright lustre.  On many crystal faces and edges the true burgundy-red colour of the Pyrargyrite is visible.  Areas on some crystals are naturally broken due to contact damage while in-situ.  A stunning and exceptionally fine example of Pyrargyrite from the Catharina Neufang mine in the Harz Mountains.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781009088847,"sku":"CC18823","price":3331.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC18823_9ad0b456-1dc3-48a7-9ff4-97b86bef14fc.jpg?v=1783975370","url":"https:\/\/crystalclassics.co.uk\/products\/pyrargyrite-14","provider":"Crystal Classics UK","version":"1.0","type":"link"}
