Chains, called riazni, were created from small cloisonné enamel medallions. The chains may have joined layers of dress, been worn as necklaces or bracelets, or used to suspend circular or crescent-shaped pendants known as temple pendants or kolti. Rus' women wore temple pendants in pairs, suspended beside the face, at the temple, as part of their elaborate headdress.
