Tara Brooch

An Irish penannular brooch covered in filigree, granulation and amber on both sides.
The brooch was found on the shore at Bettystown in 1850 and named Tara by a jeweller to sell copies. It was copied widely in the Celtic Revival of the 19th century. It is in the National Museum of Ireland.
