Victorian cravat or stickpin with a radiating guilloche enamel center in shades of tangerine and pink, encircled by dots of white enamel. Testing is inconclusive but I believe that the piece is sterling with a gold wash. The top measures 3/8” around and the entire pin is 1-5/8”. The condition is excellent with no enamel loss. Small but striking. I have seen the same design in a pin hallmarked Marius Hammer of Norway.
