{"product_id":"quartz-62","title":"QUARTZ","description":"The Comobabi Mountains lie to the west of Tucson in Pima County and are not renowned for noteworthy mineral specimens. However, one unusual type of specimen - Quartz apparently replacing Calcite crystals - have been reported, albeit rarely. This interesting large miniature-sized specimen from Paul Matt's collection presents small, but well-defined pointed (possibly scalenohedral) Quartz replacements after Calcite, but rather than being just white, they are a pale peachy-orange with their colour nicely zoned giving a lovely appearance. Individually, these crystals reach 8 or 9 mm in length developed as freestanding crystals and clustered radiating sprays upon a more massive Quartz matrix. The surface of these crystals is very finely crystallized, providing a sugary texture. A few of these crystals, mostly towards one end of the specimen, have their terminations missing, but the overall presentation is still really fine for such an unusual and rarely seen occurrence.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46793883975855,"sku":"CC57288","price":250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC57288.png?v=1794306598","url":"https:\/\/crystalclassics.com\/products\/quartz-62","provider":"Crystal Classics","version":"1.0","type":"link"}
