Rare enamel filigree ring circa 1920's with pink spinel (manmade) center stone. Such an unusual color combo with green and orange enamel surrounding pink stone. Ring also has elaborate filigree work. There is some enamel loss (see photos). Stone moves a little in setting when worn but is secure. Ring has decorative etching on sides but back of band is plain so should be able to be sized. Ring size = 5.25. Faded "14k" mark inside band.
