Vintage brooch in metal alloy and glass stones.
It is missing one of the tiny crystal stones and some other may have a touch.We are not sure if any of the small stones on the sides have been changed (see images)
From the star-shaped mark, everything seems to indicate that it is from the firm H.D. Merritt & Co.
Approximately around 40.
