18k Gold Pendant + Solid Silver + Crystal + Mother of Pearl Antique Jewelry

  
Made of solid silver encrusted with crystal or glass stones? The bail is made of solid gold (18 carats). No hallmark, but the metals have been tested. There is a piece of mother-of-pearl inside. Jewelry from the late 19th century or early 20th. Pickup possible at my place in Paris 9th arrondissement.
