Vintage Russian 14K rose gold diamond emerald ring

14K rose gold with 14k white gold top. Hallmarked with Soviet Russian assay mark & pictorial mark. I can't identify the Maker's Mark but appears to be stamped, as well. Center stone is a natural, round emerald approximate 3.25mm that's a vivid shade of green. Surrounded by hand miligrained 14K white gold and 8 round brilliant cut diamonds, approximate .24ctw. Color H-I, VS1-VS2 clarity. The shape & style is similar to the navette rings that I have but this one is more comfortable & delicate.
