Stunning Irish Celtic Revival Silver Tara Brooch & Shamrock.
It measures approx 1 & 3/4" long one in Fine detail and is mounted with a shamrock with connemara marble inserts.
The Brooch is a similar design to a Adie & Lovekin design of the same period but there is no hallmarks or makers name it is just stamped Silver so possibly an american copy.
