Multicolored enamel fish on antique sterling silver brooch pin, marked RD.,1904. The detailing on these fish is superb, with brilliant guilloche enameling in blues, greens, yellow, and silver, rendering the fishes’ bodies and scales with great artistry. Measuring 1-7/8” by 1-3/8”, this pin is also a watch holder. It is marked RD, 1904, Sterling, and also has the British crown and lion passant, somewhat obscured by the upturned hook. There is a light scratch mark at the upper left, last photo, and no enamel loss.
