Chalcedony

Known since antiquity, chalcedony takes its name from the ancient city of Khalkedon on the Bosphorus. Formed through post-volcanic processes, it is often found near hot springs, sedimentary zones or regions shaped by significant seismic activity. Its colour ranges from grey-blue to grey-green or grey-white, marked by a soft, almost milky translucence. Admired by many civilisations, it was valued by the Babylonians for its durability and worn by the Romans as a talisman for eloquence — Cicero is said to have carried chalcedony during his speeches. Over time, various traditions have attributed calming properties to the stone, believing it could ease tension or bring emotional clarity. Today, its gentle hues and understated presence continue to inspire designers such as Lito, Sophie Buhai, Anaconda and Grainne Morton. A gemstone that has crossed centuries while preserving its quiet, steady character.
