This beautiful antique small brooch or tie pin is marked to the back of the silver setting with the mark H Gr active 1918-1937. It is also marked 830S.
This is a rare piece.
The brooch has a rich blue design which radiates out from a central convex white enamel centre. The design to the border features white enamel and a scalloped silver edge.
There is a C type catch and a pin that ends at the edge of the brooch. We would date this to around 1920.
There is no damage to any part of this brooch or pin. There are no chips or cracks to the enamel. There are many fine dark spots within the white enamel border from when it was made.
The pin is 12mmx 17mm
