Dakota Stones offers you some of the highest-quality Blue Chalcedony rounds from Turkey mines. The natural color of this A-grade material was normally only achieved by dyeing or heating lower-grade material. The natural color and clarity of this material is normally reserved for settings in silver jewelry or stone carvings where gram and carat pricing is used, but we were able to secure this material and bring these vibrant blue beads to our customers. Blue Chalcedony has played a role as a trade material in the Anatolia region of Turkey for centuries. The name of Chalcedony is originally “Kalsedon,” which comes from the name of ancient Anatolian port named Kalkedon. That name is now used around the world for materials with the same chemical composition.
