This is a stunning vintage pin or brooch by the jewelry designer Walter Lampl. It is gold filled over sterling silver and it is set with a beautiful jade stone carved in a floral design. I have read that Lampl, who loved jade, brought a number of these carved stones back from China. It is marked with Walter Lampl's mark (W L) and it is also marked 1/20 12K G F on Silver. It fastens with a rollover safety catch.
It measures 1 1/2 inches in diameter and it is in very nice condition with only some finish wear primarily around the catch.
