{"product_id":"faceted-oval-chrysocolla-in-quartz-gem-silica","title":"1.73ct faceted oval chrysocolla in quartz 'gem silica'","description":"\u003cp\u003e\u003cspan style=\"white-space: pre-wrap;\"\u003eQuartz is my second favorite gem because of the huge amount of inclusions it can have. This one has copper-bearing chrysocolla inside making this the highly collectible variety of chalcedony (kal-SED-nee) known as Gem Silica. It is 1.73ct in weight and measures a calibrated 9x7mm. It's untreated, likely from Arizona, semi-transparent (most is translucent at best), and is decently cut. It is a beautiful greenish blue with good saturation and medium to medium light tone. There are a few green inclusions; probably malachite which proves its natural origin. Usually seen as cabs, this faceted one is on the unusual side. \u003c\/span\u003e\u003c\/p\u003e","brand":"Gem Fanatic","offers":[{"title":"Default Title","offer_id":51000684609788,"sku":null,"price":519.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0802\/2920\/4220\/files\/173gemsilica2.jpg?v=1787260828","url":"https:\/\/gemfanatic.com\/products\/faceted-oval-chrysocolla-in-quartz-gem-silica","provider":"Gem Fanatic","version":"1.0","type":"link"}
