Though the Celts have been revered for their sensational jewelry making skills far advanced for their time and tools, they actually never made rings. The Celts are among a select group of civilizations including the Assyrians and the Eskimos that have never produced nor worn rings. However, Celtic rings styles are easily the most widely popular today. Claddagh rings which represent love, loyalty and heart are commonly worn as signs of devotion, as engagement rings or wedding rings. Puzzle rings feature Celtic styling. Other rings feature intricate Celtic knots that represent unity, love, nature, and the divine.
