Chalcedony Beads

Chalcedony is the term applied to most cryptocrystalline quartz. Cryptocrystalline means that the crystal structure is too small to be seen with a standard microscope. Chalcedony beads range from Semi-Transparent to Opaque in quality. They come in a variety of colors and can be color enhanced. Chalcedony and Agate are Quartz Varieties which may discolor or loose color when color treated by dye. Please allow for possible color change in any treated Chalcedony or Agate.
