Pearl & AB Rhinestone Vintage Silvertone Brooch Pendant Signed WW or MM EUC

This exquisite vintage silvertone brooch features two shimmering faux pearls, two tiny rows of sparkling clear rhinestones and sparkling deep pink fiery aurora borealis rhinestone accents in a lovely asymmetrical pattern around large square cut faceted dazzling rhinestones. This combo pendant brooch is signed- I am unfamiliar with mark, although I've seen it on other pieces. Either WW or MM. Nice unique piece.
