What Is Blue Chalcedony?
Chalcedony is a form of quartz made of crystals so tiny they can only be seen under a microscope, which gives it its smooth, waxy, softly translucent look. It comes in many colours and goes by many names: carnelian, agate, onyx and chrysoprase are all chalcedony. Blue chalcedony is the gentle, cloud-blue variety, found in Namibia, Brazil, Turkey, Indonesia and the USA.
The name is often linked with Chalcedon, an ancient Greek port near modern Istanbul. Chalcedony has been carved into seals, cameos and amulets for thousands of years, and Roman orators are said to have carried it to help them speak with calm and clarity.

Is My Blue Chalcedony Real?
Natural blue chalcedony has a soft, slightly cloudy translucence and a waxy shine, with gentle variations in its colour. It's often confused with blue lace agate, which is chalcedony too but has clear lacy bands. Bright, evenly coloured blue beads may be dyed agate or glass; dye often gathers in cracks, and glass may show tiny round bubbles.
Cleansing and Caring for Blue Chalcedony
At 6.5 to 7 on the Mohs scale, blue chalcedony is happy to be worn every day. Clean it with lukewarm water, mild soap and a soft cloth, and keep it out of strong, direct sunlight for long periods, as some blue chalcedony can fade. Cleanse it with moonlight, sound or smoke. Our guide to cleansing crystals and guide to charging crystals explain each method.
