VINTAGE MOTHER OF PEARL & INLAID DOUBLET SHELL Necklace 18" NWOT

I say this is Vintage because the person we got several of my pieces in the estate sale was older and a lot of the high quality jewelry was vintage. This piece is one of the nice ones, should probably be about 64 by my research but i am going with 1/2 that amount. Mother of Pearl and shell 18"
