This brooch came into our possession in the early 60s but beyond that, I have no idea of its age,
I am not in the jewellery trade so have limited knowledge about its origin and no idea of its true value. I have found similar items on the net and the price is between £150 and £280.
It appears to be silver and it is of good quality and has no obvious damage.
Please assess for yourself you could bag yourself a real bargain.
