VTG Dessert Set in Black (China or glass?) with Silver Overlay Design has 15 pieces. There are four 7 1/2 inch octagonal shaped dessert plates, one 10 1/4 inch from side to side 10 sided cake plate (handle to handle is 12 inches), four cups and four saucers all with octagonal shape, and a matching creamer and open sugar dish. True onyx black color. The silver overlay is worn on the one dessert plate I’m point to. Otherwise the overlay is in very good condition. The glass or China is beautiful with no issues. There are no markings on the bottoms of any pieces.
