Vintage Dichroic Glass Pendant on Sterling Chain

Gorgeous estate piece, vintage dichroic glass pendant measures 1 1/2” x 3/4”. It is mounted on a sterling bail marked 925 and I believe there may also be an artists signature here, although I cannot read it. Chain is also marked 925 at clasp and measures 18”. Pendant is freeform; has some teal, pink, gold blue and silver. I have not cleaned the silver on this piece; I leave that to the buyer’s discretion.
