This is a very popular Art Deco style from the 1920s.

This ring has an emerald cut shaped flat piece of black onyx in the center. The middle of the onyx has a diamond shaped piece of gold mounted in the center with a 0.01 carat old single cut round diamond. Diamond has SI clarity and H color. The frame around the stone is rectangular and domes down toward the edges. There is mill grain detail etched along several edges.

The ring is stamped 10K and weighs 2.7 grams. Ring is a size 4.5.

The ring is in very good condition overall. There is some wear to the prongs on the diamond but a few have been re-tipped at some point.

This ring is in original condition and has not been polished. We would be happy to polish and rhodium plate it at the buyer's request. Also, the ring can be sized within a certain amount and for an additional fee - message us with the size you need for a quote.
