Vintage Enameled 5 Triangle Necklace Black with Black Chain New Old Stock Brass?

Vintage Necklace Brass or Similar Material with Black Enameled Triangle Shaped Pieces. (Believe they are enameled not 100% Sure). Black and shiny. The back of the pieces are brass or similar. They do have weight to them. Not so much they will be dragging you down but not at all flimsy. See photos of the back of the pieces. The chain is black in color. Approx: 8" Long. This is vintage from 1980's to early 1990's. New old stock. This was from an Estate Sale where jewelry was from a jewelry store. I also believe but not 100% certain this maybe Beautiful Jools. (This is what the majority if not all the jewelry in the Estate Sale was. ) No Defects. Non smoking home.
