» Beading Definition: Chalcedony
Similar to Carnelian and Agate in structure and sheen, Chalcedony is a microcrystalline quartz of the same family. Like Agate, it can occur in a variety of colors. It has a waxy sheen when polished and may have veins, bands or spots of color running throughout. Because of its moderate hardness, it can be cut into a variety of shapes. Generally speaking, Chalcedony is never used in its natural rough form as it takes polishing to bring out its hidden beauty.
Examples of Chalcedony include carnelian, agate, cat's eye and jasper.
