FB51 - Chalcedony - 9000€
Mamuju area, Sulawesi Barat Province, Sulawesi Island, Indonesia
Size: 15.5 x 12.5 x 6.8 cm
Watch Video

A rather large amount of botryoidal chalcedony specimens from Sulawesi Island has flooded the market in 2016. But as with every mineral, there are always a few individual pieces that exceed all others in quality and aesthetics. This is one of the very finest in this size of them all!
A mass of intensively purple calcedony spheres is clustered on a greenish beige matrix which provides a fantastic background. This matrix is in fact completely covered in small chalcedony crystals as well but the different color makes for a brilliant contrast. The backside is fully crystallized and perfect, making this piece a floater.The chalcedony is of absolutely best quality considering color and the silvery shimmering surface. Admittedly there is a small contact at the front and a couple of damaged crystals here and there but the exceptional aesthetics and outstanding quality more than make up for that minor drawbacks. A large showpiece that presents itself as the queen of chalcedony!
