A startling figure is depicted on this Art Nouveau 10K yellow gold pin, with ruby eyes and a diamond mouth. The animal-like devil-like figure is beautifully designed, and it makes this piece completely unique. The Art Nouveau movement started right at the beginning of the 20th century, which makes it also a genuine antique. The diamond in its mouth is H (white) color, with an SI1 clarity, making it quite beautiful. Altogether it creates a wonderful picture that belongs on your lapel.
