{"product_id":"malachite-with-quartz-15","title":"MALACHITE with QUARTZ","description":"The Tenke-Fungurume area in the Kolwezi mining district, DR Congo has become a centre for weird and wonderful geochemical processes and the resultant fascinating mineral specimens. Most of these processes revolve around copper and silica mineralization. This latest find involves 3-dimensional radiating acicular sprays of Malachite totally encapsulated with Quartz. This small cabinet-sized display specimen shows this new form really well. It features a finely crystallized cream to grey Quartz-lined open cavity in chert, within which two main pale peppermint-green sprays, reaching 2 cm in diameter sit at either end of the cavity, one with another spray attached to it, the other totally isolated and presenting perfectly all around. These sprays have a frosted appearance where the fine coating of Quartz is translucent to opaque, coating the individual filaments of Malachite underneath. Their colour, with a hint of blue, suggests that perhaps the underlying Malachite has altered partially to Chrysocolla, and later tiny crystals of dark green Malachite can be seen as sparse grains upon the sprays and on the Quartz lining the cavity. The delicate sprays are totally undamaged, providing a stunning display of this amazing new association from Tenke-Fungurume.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":58716323283279,"sku":"CC63306","price":886.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC63306.jpg?v=1788879625","url":"https:\/\/crystalclassics.co.uk\/products\/malachite-with-quartz-15","provider":"Crystal Classics UK","version":"1.0","type":"link"}
