We cut this piece of Arizona silicated chrysocolla ourselves in Jaipur, India, as a 15.38 carat emerald cut, letting long step facets and clipped corners show off its deep blue-green and teal colour and the darker matrix patterns that drift through it. From there it travelled to Canada, where Broken Ox Creations 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.

Silicated 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.
