silver tulip brooch made by jensen I believe it is one of the very early ones as just has 100 on it with no letter after it. It also has a blue stone . The markings are 2 round ones one with the name in and the other with 830 the both have dots around them. also the 100 does not have a letter after it. The front of the brooch is in very good condition The back were the pin goes into is missing.
It use to be my nanas my dad's mum, sadly neither are with anymore
