Wonderful and rare Art Nouveau horn wings signed on reverse GIP for George Pierre. (See p. 13 in Ginger Moro’s “European Designer Jewelry”.) Signature is carved on reverse, with a brass clasp typical for the period. Pierre designed from approximately 1915 to 1936. This has a brown centre stone – I do not know what material this is made of. Feels very cold to the touch so could be glass; could also be carnelian or chalcedony. Measures 3 inches long by 1/2 an inch wide.
