These are flapper pearls from the 1920's that have been restrung a few times with a hand carved mother of pearl enhancer, that is removable. They are 100" long and absolutely beautiful.
The second picture is a picture of a single strand of pearls that were my grandma's pearls with a 14K and diamond clasp. The pearls are pretty well matched and the luster is great! They are not perfectly round, but very nice.
Any information is appreciated!
