Rare OOAK Vintage Jeweled Clutch Bag

The bag was purchased from an unusual vintage store in Greenwich Village/NYC -It has a brass and rhinestone vintage stamping on the front. I was told the rhinestones are from an old 1950's necklace. The green rhinestones are intact and vibrant. -Clutch is 6" deep and 8" wide -Magnetic closure -I think it's leather but I cannot be sure -Please note the bag is "vintage", so it has a few minor knicks here and there but I'd say overall it's in great condition.
