Antique Mourning Portrait Necklace Jewelry Edwardian Era Vintage

Description

This was bought at an Estate sale in Boston.
The lady of the house did not know much about it, just that it had been sitting in a jewelry box for a long time.
The beading seems to be plastic and the pearl like balls on it seems to be chipped a little. Obvious wear to the age of this piece.
I have taken zoomed in pictures to indicate the details of this necklace.
Please have a look and message me with any questions.
