GORGEOUS VINTAGE 3 PIECE NECKLACE, EARRINGS, & BRACELET SET PATENT 3427691

This is for a gorgeous vintage patent 3427691 gold tone with a black and white stone necklace, earrings, and bracelet set. This belonged to my sister, and I do not know anything about these pieces. This may be Swarovski, but I can not be certain. The reason I say it may be Swarovski is because my sister had a couple of other necklaces that looked exactly like this (They are also listed, but they only come with the necklaces and not earrings and bracelets). The necklace is about 29.5 inches, the bracelet is about a little over 7 inches, and the earrings drop almost 1.5 inches. You get everything you see in the pictures :) If you have any questions, please feel free to ask. I will do my best to answer :) Please refer to pictures for they are part of the description :) Thank you :)
