Tara Brooch, AD 700. "This is one of the masterpieces of the Early Christian epoch: the simplicity of its general outline counterpoints an amazing complexity of techniques and assemblage of materials--gold, silver copper, amber, glass, enameling, filigree, wire-beading, granulation, inlaiyng and soldering are all used.Do you have any info on what this item is, (in reply 5)? It’s similar to an item my brother-in-law found when metal-detecting, and I was wondering if you know any details about the one you posted. Thanks.
