Vtg 1940s MIRIAM HASKELL ? brass filigree faux pearl cabochon necklace pendant

Unsigned Miriam Haskell ? pendant....it measure 3" x 2".....In very good vintage condition, but the two rings that attach the two parts are silver in color, but they look original, because we see no sign of welding..... On the other hand, it is not visible from the front!
