Round Pink Chalcedony Beads 4mm | Sold by 1 Strand(7.5") | BS0073

For most of time, chalcedony was thought to be a 'fibrous' variety of cryptocrystalline quartz, but more recently it was actually discovered to be a combination of quartz and another silicate mineral; moganite (a polymorph of quartz). Both quartz and moganite share the same silicon dioxide chemical composition, but they have varying crystal structures. Moganite is monoclinic, while traditional quartz belongs to the trigonal crystal system. Chalcedony forms with a hexagonal crystal structure.
