Vintage Brass and Black Beaded Pendant Necklace

RELISTED....See NEW LISTING Antique jet floral long necklace with what looks like a brass or darkened goldtone chain with black beads & crystals. Darkened and brushed goldtone pendant frame with clear, black and grayish rhinestones. Been in my jewelry box forever & the very center rhinestone may be missing but it's very hard to tell. Chain is very long with an extension plus clasp stamped SHA and possibly a vintage Avon piece? Very unique & gorgeous. Please see all pictures for condition measurements willing to negotiate!
