Botryoidal Blue Chalcedony
About Blue Chalcedony
Chalcedony is a cryptocrystalline form of silica, composed of very fine intergrowths of quartz and moganite. These are both silica minerals, but they differ in that quartz has a trigonal crystal structure, while moganite is monoclinic.
Blue Chalcedony forms botryoidal crystals. We are providing such crystals as specimen flats and for gemcutters as crystal surface.
