This beautiful Art Nouveau-design pin features three cabochon carnelian (onyx) stones that are bezel-set and one long polished carnelian bead completing the design. The setting is of fine cast construction and is marked "925." It measures 1 5/8" wide and 1 7/8" long. There is a safety catch. The pin is modern and dates from between 1970 and 1985, a period of Art Nouveau revival. It is in perfect condition.
