{"product_id":"malachite-on-quartz-6","title":"MALACHITE on QUARTZ","description":"One of several modern copper mines that have produced really interesting aesthetic Malachite specimens, Mindingi mine in Kambove District, Haut-Katanga, DR Congo is typified by Malachite associated with beds of crystallized Quartz. In 2024, we saw a small number of specimens of excellent, large, Primary Malachite crystals on Quartz veinstone. In 2025-2026, the Malachite is a much deeper green and forms spherical aggregates on cream to white Quartz.  Better still, the 'balls' of Malachite display superb chatoyancy - the cat's eye effect - across their velvety surface. This superb small cabinet specimen presents this perfectly, and many of the 'bubbles' of Malachite merge slightly, to give the impression of some sort of organic fungus-like growth. The bed of Quartz upon which the Malachite grows is a vein cutting through buff-coloured sandstone\/chert.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46793844785327,"sku":"CC54624","price":800.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC54624.png?v=1782214228","url":"https:\/\/crystalclassics.com\/products\/malachite-on-quartz-6","provider":"Crystal Classics","version":"1.0","type":"link"}
