A stunning apple green chrysoprase (a nickel-rich variety of chalcedony) that is lined with parent rock. This exceptionally aesthetic piece on offer comes from the Candala Chrysoprase mine site in Marlborough, Queensland, Australia. The offered piece is cut to resemble an oval cabochon measuring 14.0 x 6.26 mm. (The concentric circles on the surface are just a reflection of the camera optics, there is nothing like that on the stone).
