This is an art nouveau style modern ring of translucent cobalt blue and green enamel in excellent condition--not ever a scratch. The 3/8 by 1/4 inches peridot is Granny Smith green and saturated with color, safely set snag-proof in my favorite bezel-setting. The shank tapers at the back to about 1/4 inch. The colors you see are true--took a lot of work! The ring is size 9 and not sizable.
