About Chalcedony Jewelry
Named after an ancient town on the banks of the Bosporus, chalcedony is porous silica with intergrowths of quartz and morganite minerals. The earliest recorded use of chalcedony was for projectile points, knives, tools, and containers such as cups and bowls. Man-made weapons and tools from varieties of chalcedony are highlights in Stone Age museum exhibits.
Chalcedony: Gems for Protection, Sustenance and Beauty
Today, chalcedony is a popular gemstone as the material is beautiful, abundant, durable, and reasonably priced with a nearly unlimited variability. Legend has it that a thief bound for execution may find freedom and good luck if he slips a chalcedony under his tongue.
Chalcedony Jewelry Care & Handling
While chalcedony is reasonably durable, it can take on scratches so care requires no more than a gentle polish with a soft cloth. Chalcedony's color can be influenced by sunlight and should be stored away from direct light.
