This is an awesome combination specimen. The host rock is natural chalcopyrite which has some deep metallic blues and purples on it. The front side of the specimen has dioptase which quartz has grown to coat in a druzy formation all but one single dioptase crystal (in the top right corner). This gives it a kind of icy and shimmery appearance with those deep blue-greens of the dioptase still visible throughout.
This specimen measure ~8.9cm wide x 7cm tall x 4.5 cm long
