{"product_id":"ludlockite-with-tennantite-and-quartz","title":"LUDLOCKITE with TENNANTITE and QUARTZ","description":"Ludlockite is one of the all-time classic rarities from Tsumeb mine having been discovered there during the 1960s and named after the two mineral dealers - Frederick Ludlow Smith III and Charles Locke Key - who provided the material for study. Often seen as bundles of loose, off-matrix, burnt-orange coloured fibres, this miniature specimen is a superb, and rare example, of Ludlockite on matrix. This matrix is massive dark grey metallic Tennantite and the Ludlockite forms radiating sprays (to 5 mm across) of silky acicular crystals. The largest area of Ludlockite reaches 8 mm across.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":57780961608015,"sku":"CC15805","price":1850.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3748\/2063\/files\/CC15805.png?v=1779745830","url":"https:\/\/crystalclassics.co.uk\/products\/ludlockite-with-tennantite-and-quartz","provider":"Crystal Classics UK","version":"1.0","type":"link"}
