{"product_id":"zincolivenite-5","title":"ZINCOLIVENITE","description":"A very fine specimen of rich green Zincolivenite from the Tsumeb mine in the Oshikoto Region of Namibia.  Lustrous Zincolivenite crystals measuring to 9 mm display curved, fan-like, parallel growth covering a mixed matrix of Quartz and red-brown Goethite.  Zincolivenite is a relatively new species within the Olivenite-Adamite continuous series.  Formerly named zinc-olivenite or cuproadamite (depending on its composition), the mid-series section is now the distinct species Zincolivenite.  See the excellent paper Tsumeb: Zincolivenite and the Adamite-Olivenite Series by Malcolm Southwood, Martin Števko and Paul Carr in Rocks \u0026amp; Minerals, Vol. 95, 2020, Issue 3.  A classic miniature of Zincolivenite from Tsumeb, complete with its own purpose made acrylic base, in which a negative profile of the specimen’s base has been milled.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57781510701391,"sku":"CC8063","price":1184.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC8063_74e13ce1-9524-4d82-a8b5-38c97f579ea4.jpg?v=1783992278","url":"https:\/\/crystalclassics.co.uk\/products\/zincolivenite-5","provider":"Crystal Classics UK","version":"1.0","type":"link"}
