These pearl starter/Start-Her necklaces by Orienta were trademarks of Leys, Christie & Co., Inc. in NY, more information for which can be viewed on their website. Unfortunately I do not know the 4 pearls' millimeters on this necklace, which has been warehoused for many years after store closing. Pearls appear to be same size. All original tags shown. Price on tag most likely wholesale, while affixed sticker covering tag on one side, retail at that time. Box in good shape. Measures 15", photo 6.
