This is lovely unsigned vintage brooch that looks like unsigned Trifari. It dates to the 1930s or 40s.
There are poured glass stones of blue and red flanked by tiny white rhinestones. They are set in open back setting so the light can shine through.
This looks to be be vermeil, gold wash over sterling, but it is not marked in any way. This gorgeous unsigned designer brooch is in excellent condition. It measures approximately 3" by 1" at it's widest.
