This brooch was in my mothers possesions, I have no idea about antiques, could someone advise if this is a genuine antique as I cannot find the mark on the back of the brooch on the internet and do not wish to sell something if not genuine.
I doubt that based on a picture anyone could verify the age or make of a Brooch. You need to ask perhaps in a Jewellers or Antique Shop so that it can be seen and examined properly.
