This is an exquisite piece, c. 1910. It is made of 830 vermeil. The filigree-bordered circles suspend 3 blue enamel flowers with white centers. The filigree design between the circs have a similar dangle with a central, white cab. This spectacular brooch measures 1 1/2" across (1 3/4" w/ extended pin). It measures 2 5/8" from top to bottom. The back is marked 830 with a maker's mark I cannot make out.
