Blue Chalcedony (Marbled) 10mm Round 15-16 Inch Red green and brown to theBlue 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. Known in antiquity as the Speakers Stone, it is believed to have been worn Cicero, the great Roman orator. These strands were cut into beads with some of the material the Chalcedony was mined out of remaining, creating a unique "marbled" look.
