Vintage blue zircon and diamond engagement ring. A vivid blue rectangular shape, step cut blue zircon shines from within it's diamond halo. The zircon has a lovely facet pattern and a nice high crown. It's not often we find blue zircons in step cuts. Framing the blue zircon is a halo of twelve single cut diamonds. The diamonds are set into a diamond cut top which gives the impression of there being more diamonds. Adding to this effect is a row of delicate milgrain beading right at the outer edge of the blue zircon. The gemstones are set into a white top on a slender gold band which pinches in near the gemstone set top. Circa mid 20th century.
