Vintage hand-engraved amethyst ring

This vintage ring features a long slender amethyst surrounded by seed pearls strung on a wire.  The hand-engraved detailing is beautifully done, even extending to the bottom of the ring.  There are even tiny enamel accents of green and black at the sides; this was made by a craftsman.  The ring measures about 7/8” along its longest dimension and is a finger size 7; it may be sized up or down by at least one size.  (There are a few pearls missing.)
