 Chalcedony probably was named for the ancient Greek town Chalkedon in Asia Minor, which is today part of Istanbul.
Chalcedony was used in the Mediterranean region as early as the Bronze Age. In the Palace of Knossos ...on Crete, Chalcedony seals have been found dating back to 1800 BC. Hot wax would not stick to it so it was often used to make seal impressions.
Chalcedony is a form of quartz with many, many varieties including such very different stones as Carnelian and Moss Agate. Generally in the gem world, the term Chalcedony is reserved for the waxy looking, translucent blue and brown variety.
