Chalcedony | Silver Street Jewellers


Posted by Laura Greenshields on



Chalcedony is a crystalline type of silica consisting predominantly of quartz and moganite. Chalcedony has a shiny luster, which can be translucent or semitransparent. The stone gets its name from the town Chalcedon in modern day Turkey.





Chalcedony was used at least 32,000 years ago in Central Australia to make tools. Pre-contact uses documented today include typical stone blades. In the nineteenth century, Idar-Oberstein, Germany, became the world's largest all-purpose manufacturing center for chalcedony, operating most frequently on stones from Latin America.  The Torah discusses the Breastplate of Aaron, which holds twelve gems reflecting the tribes of Israel one of which was chalcedony.
