Wonderful deep green emerald and diamond cluster ring dating to the Art Deco era. This platinum ring is set with an emerald cut emerald framed by a diamond halo. The contrast between the deep green of the emerald and diamonds is stunning. Rather unusually the diamond halo is slightly wider in the middle giving this ring a more bubbly and a less sleek look. The platinum shank is about the same width all the way around and comes to a slight taper where it meets the gemstone set top.

This piece looks as though it may have a marriage. The gemstone set top has been attached to a platinum band to make a ring. It makes a good ring which is set low to the finger with the band made to allow a low profile ring to sit snugly next to this ring. Circa 1930s, date of conversion unknown.
