These are the semi-precious Blue Chalcedony smooth, faceted, carved and shaped beads or components we currently have in stock.

Chalcedony is bluish-grey-white gemstone. It can be rather translucent, with a waxy look to it - varying to somewhat opaque. It usually is prefixed by the word "Blue" to distinguish it from the geologist's term "chalcedony" meaning a "cryptocrystalline quartz". The blue form is the best known version of this type of gemstone. The blue color of chalcedony is often (but not always) enhanced by heat treating.

Chalcedony seems very smooth and hard when polished, but it actually is microscopically porous, making it easy to dye. In fact, if you accidently splash coffee on your chalcedony pendant, it can stain the stone - so be sure to rinse any spills with lots of water immediately.
