Beautiful Smokey Rhinestone Ball Necklace

I found this gem at a thrift store and fell in love with it. It is pretty unique I think with its smokey color rhinestones and it has pear and round shapes. It is hard to see in the photos, but there is this real detail to the metal frame of the ball where the stones sit. I at first thought the rhinestones might have gone bad and turned this gray color, but I no longer think that because it sparkles very nice in the sun. I was trying to find out who may have made it, there are no marks.
