{"product_id":"pyromorphite-on-coronadite","title":"PYROMORPHITE on CORONADITE","description":"The famous MMM mine at Broken Hill in Australia worked the line of lode orebody and is situated within the city of Broken Hill, towards the north-east.  On this 6 x 4 cm miniature, Pyromorphite crystals coat both sides of a flat plate of Coronadite, a lead-manganese oxide of matt, sooty black appearance.  The Coronadite is mainly masked by the butterscotch toffee coloured Pyromorphite and a very light creamy-tan fine-grained altered sandstone.  The Pyromorphite forms glassy, parallel sided prisms with a simple, flat pinacoid, the latter often a slightly lighter shade than the prism.  The crystals range between 1 and 5 mm long and where they contact the Coronadite, appear a greyish graphite-tinged pale orange.  The base and edges are coated with fine acicular Pyromorphite crystals of pale straw to limey lemon.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780495188303,"sku":"CC11845","price":592.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC11845_d0ba8dcd-452f-479e-a907-aece3174d88f.jpg?v=1783968950","url":"https:\/\/crystalclassics.co.uk\/products\/pyromorphite-on-coronadite","provider":"Crystal Classics UK","version":"1.0","type":"link"}
