This is a beautiful 18k solid gold ring set with a completely natural emerald (not oiled to mask imperfections). The piece has what I call a crown pattern around the bezel and fancy details on the band.
The gemstone is from Brazil and has classic emerald green color. It is almost completely free of inclusions and is clean & bright. Good sized natural emeralds that are clean like this are extremely rare.
The ring at its widest point is a little over 5/16” wide (at the front – top to bottom) and the band is approx. 3/16” at the back.
