{"product_id":"primary-malachite-on-quartz-9","title":"Primary MALACHITE   on QUARTZ","description":"'Primary' Malachite is an unusual mineral, but one which can be stunningly beautiful. The 'Primary' prefix is rarely used for minerals, and is not, as you might expect, used to denote that it has formed in a primary mineralizing environment, as opposed to secondary alteration. Instead, it denotes that most Malachite occurrences are replacements of other minerals, or show forms - like - stalactites - rather devoid of individual discernible crystals. So, it is extremely rare to see Malachite in its own discrete crystals, other than acicular sprays. This miniature specimen is a fine example from a recent exceptional find at Mindingi mine in Kambove District, DR Congo. The triangular, almost sphenoidal crystals are exceptional in their shape and measure up to 8 mm across. They are semi-translucent deep bottle green to forest green in colour with a glassy to velvety lustre and are richly scattered across a thin layer of contrasting white to colourless Quartz crystals. A couple of the Primary Malachite crystals have the very slightest of abrasions, but careful inspection is required to spot these. Otherwise, the crystals are superb in quality.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46584948293807,"sku":"CC50902","price":400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC50902.png?v=1771867058","url":"https:\/\/crystalclassics.com\/products\/primary-malachite-on-quartz-9","provider":"Crystal Classics","version":"1.0","type":"link"}
