This is a very lovely antique Art Nouveau pendant or lavalier in 9K gold (tested) set with cultured seed pearls, two small peridots, and one larger round cultured pearl at the bottom. The design incorporates flowers, leaves and a crescent moon. The gold is rose gold and the craftsmanship is excellent.
It measures 1 1/2 inches long (including the pearl drop) by 1 inch. It is in very good condition. No chain is included.
