Vintage Baroque Pearl Gold Tone AB Aurora Borealis Rhinestone Brooch READ

Vintage Baroque Pearl? Gold Tone AB Aurora Borealis Rhinestone Brooch READ I do not know the authenticity of the pearl(s). They do not feel cold to the touch (if that means anything). There is one rhinestone on the very bottom that is missing. I think it was actually crushed and moving it about to take pictures and looking through the jeweler's loop it fell out (see picture). Please see pictures for details and judge for yourself on the condition. The pictures are part of the item's description. Thank you for looking.
