Sterling silver with 18ct rolled gold trim on the edges. The intricate decoration is inspired by the ornate filigree that can be seen on the 8th century Ardagh Chalice on view in our An tSeodlann/The Treasury exibition at the National Museum of Ireland - Archaeology. A beautiful gift for that special occasion. Made in Dublin by Boru and hallmarked at Dublin Castle. Width 9mm. Inside measures 52mm high and 60mm wide (87mm when safety chain is open).
