This stately vintage 3-stone anniversary or engagement ring is highlighted by an emerald, side diamonds and diamond halo. The emerald is an oval with rich green color, measuring 5.03 mm by 3.44 mm equaling approximately .25 carats in total weight. Sitting between are two round brilliant-cut diamonds that are G-H in color and VS2 clarity grade, that equal approximately .24 carats in total weight, surrounded by a halo of 14 diamonds G-H in color and VS2 to SI1 clarity grade, equaling approximately .28 carats in total weight. We believe this setting is from the 1950s with its fanned open gallery and very thin band. The width of the gemstone is 7.5 mm wide and 13.0 mm across your finger. There is a very small nick on the girdle by the prong.
