Vintage Prong Set Oval Fauceted Graduated French Jet Glass Necklace

Vintage Prong Set Oval Fauceted Graduated French Jet Glass Necklace Absolutely gorgeous Victorian Black Mourning Necklace in hand cut Fauceted French Jet beads. Good condition for vintage age and wear, needs a good verdigris cleaning. Adjustable hook clasp. Measures approximately 16 in I am not even close to being an expert. At first I thought maybe this was Czechoslovakia Glass and honestly it may be, but after close inspection I think it might be French Jet. WHATEVER IT IS, IT'S OLD AND IT'S BEAUTIFUL! THANKS.
