The tara brooch is the name given to a pseudo- penannular brooch that was popular in Irish culture. This one comes highly decorated with celtic knots and accented with connemara marble and marcasite stones. Great vintage condition with little to no signs of wear. Stamped on the reverse with silversmith marks and what appears to be TJM.
Acid tests positive for sterling silver.
Brooch measures 1 and 3/4ths of an inch by 1 and 1/8th of an inch.
