Vintage Cameo Necklace. Pendant has a nice Filigree design. Pendant marked 800 which I believe indicates gold electroplate. 
Estate Find. Also Signed 800 on the clasp of necklace. Cameo pendant measures approx 1" high x 37/8" wide, not including the bail. Chain measures approx a little less than 18". Will combine shipping for purchases of multiple listings.
