From there it travelled to Canada, where \u003ca href=\"https:\/\/rubblerockandgem.com\/pages\/broken-ox-creations\"\u003eBroken Ox Creations\u003c\/a\u003e turned it into a stone-on-stone piece, setting a round faceted Brazilian amethyst in sterling silver and inlaying it right into the table. The violet of the amethyst sits against the blue-green like a small window, and the result is truly one of a kind.\u003c\/p\u003e\n\u003cp\u003eSilicated chrysocolla, often called gem silica or chrysocolla chalcedony, is something special. It is chalcedony, a microcrystalline quartz, that has taken up fine chrysocolla as it formed, and the copper in that chrysocolla is what gives it such a saturated blue-green. It grows only in small amounts, lining cavities and filling fractures in the oxidised zones of copper deposits, which is why Arizona's copper mines have long been its best-known source. And because it is quartz at heart, it is far tougher than ordinary chrysocolla, at about Mohs 7, so it holds up well in jewellery. Few kinds of chalcedony are rarer or more prized.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChemical Composition:\u003c\/strong\u003e Chalcedony, SiO₂, coloured by chrysocolla, (Cu,Al)₂H₂Si₂O₅(OH)₄·nH₂O; amethyst inlay, SiO₂\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMohs Hardness:\u003c\/strong\u003e 7\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTreatment:\u003c\/strong\u003e Natural\/None\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1pc\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eWith this product, you will receive the actual stone shown in the photograph.
