the pearls belonged to my daughter-in-laws grandmother, they were restrung into an original design that includes the amythyst from another piece of jewelry that grandmother possessed. The deep color of the amythyst accents the rose shade of the pearls. I am no expert and do not have any idea of size, but they are small, not exactly the same, but very well matched; they are attractive. The overall length is approx 22 inches, the bracelet is 7 1/4 or so. The necklace is designed similar to a chokechain, it is worn as a choker and falls down the back, obviously to be worn with a back baring dress. One end of the strand has a large circle of platinum that the other ends slips through..does that make sense? I have only ever seen one piece similar and that was in a display with the traveling Smithsonian. I intend to have it appraised for my daughter-in-law, but am always suspicious of appraisers who also buy.
