{"product_id":"dioptase-on-calcite-3","title":"DIOPTASE on CALCITE","description":"A most unusual small cabinet specimen of well-formed colourless Calcite crystals dusted with a preferential coating of Dioptase and Calcite included with Dioptase from the Tsumeb mine in Namibia.  Individual Calcite rhombs average 1 to 1.3 cm on their longest edge and are translucent colourless to creamy white.  This plate of crystals has sat vertically in a cavity wall allowing solutions to preferentially deposit sucrosic Calcite crystals tinted turquoise by finely disseminated Dioptase.  This has been followed by a deposition of 1 to 2 mm emerald green Dioptase crystals with one Dioptase of 4 mm across present.  An interesting specimen which displays nicely when stood vertically to simulate its 'way-up' position when in-situ.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46541031375023,"sku":"CC8047","price":2750.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC8047.png?v=1770223203","url":"https:\/\/crystalclassics.com\/products\/dioptase-on-calcite-3","provider":"Crystal Classics","version":"1.0","type":"link"}
