A gorgeous combination of nature's own geological art and the skill of a master carver and artist, who followed the natural patterns within the stone to split open this complete "pocket" of copper mineralization. The Malachite is polished along the natural contours, showing the void left open inside, which later filled with the blue Chrysocolla. The green Malachite formed in beautifully banded patterns contrasts with the powder-blue Chrysocolla within, for an aesthetic disaply. Superb quality, with high color saturation for both species, in a remarkable balance. With a custom lucite display base. 20 x 15.5 x 10 cm (7.8 x 6.1 x 3.9in.) and 4.2 kg.
