Pink Spinel Ring - Enamel - 14k Gold - Antique

Rare enamel ring circa 1920's with pink spinel (manmade) center stone. Such an unusual color combo with green and orange enamel surrounding pink stone. There is some enamel loss (see photos).  Ring has decorative etching on sides but back of band is plain so should be able to be sized. Ring approx = 5.5.  Stamped "14k" mark inside band.  Band is a bit thin at back but comfortable to wear.
