Comment: Conny Forsberg cut this all-natural copper-bearing US Sunstone. This variety can fill a lifetime of learning, with color effect and inclusions phenomenas, colour-changer, iridescence, di-, tri- and quad-chroic colour effects, multi-colours, aventurescence and a world of inclusions and their optical effects. See two close-ups under more images. Those inclusions and the copper strands are NOT visible to the eye. The overall impression is peach to copper with green waves in-between, the latter are hiding from the camera either because the peach is not yet ripe, or the copper is oxidized (kidding). DSEF certified from the same lot that has GIA reports with 'no treatment'. All-American gemstone, cut in Sweden, studied and ID-ed in Germany and still rescues rainforest passing by Columbia.
