Chalcedony

Chalcedony is a type of crystalized silica that is occasionally referred to also as quartz. However, chalcedony is different because of how it can be formed. While quartz is the results of almost always inorganic chemical reactions, chalcedony can result from organic reactions such as petrification (the best known example being petrified wood).

Chalcedony is not as chemically pure as quartz, leading to more interesting swirls and blends of color. Our selection of chalcedony beads are entirely naturally formed and colored, with natural impurities in the stone as a result of organic and inorganic formation processes.
