Chalcedony (Marbled) 10-13mm Chips - 15-16 Inch Stone Type_Hydrogrossular Garnet second only to DiamondBlue Chalcedony is a naturally occurring soft blue translucent stone. It is a member of the Quartz family, a form of silica with a cryptocrystalline structure that incorporates Moganite along with the Quartz.
