The exposed face shows a thick section of Green colour with elements of Blue, appearing to roll in places and turn towards Gold at certain angles. Looking into the exposed side reveals that sense of depth characteristic of Nobbies, with substantial thickness to explore.\u003c\/p\u003e\n\u003cp\u003eCurrent surface indicators sit around N5 Dark Body Tone and B3 Brightness, with Black Body Tone indications in places and flashes suggesting scope for greater Brightness as the Nobby is further revealed.\u003c\/p\u003e\n\u003cp\u003eThe surrounding Dog Rock is harder than the Opal itself. A considered approach to removing the host is important, as further tumbling would wear away the exposed Opal more readily than the harder rock surrounding it.\u003c\/p\u003e\n\u003cp\u003eAn inviting piece for a cutter who enjoys following a Nobby into its host, working with its natural shape and discovering how the colour develops beneath the surface.\u003c\/p\u003e\n\u003cp data-pm-slice=\"1 1 []\"\u003e\u003cspan\u003eIt also has appeal as a natural specimen, with the exposed Nobby offering a window into the colour while still held within its host rock.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eAuthentic.
