rare collectible and extremely beautiful vintage Riviere Paste costume necklace! please see photos as part of description. the necklace has no problems and clasp works well! the blue stones are not natural turquoise but "turquoise" paste. a few vary in shade so could be replacements but it only add ?more natural like turquoise look to it? in my opinion. it is great for Summer or even for a dressy occasion! very beautiful! fast priority shipping! smoke free environment! thank you!
