This is a beautiful 18k solid gold ring set with an ocean blue aquamarine. The piece is based on Balinese designs with intricate granulation around the bezel and some extra detail on the four ordinal points of the setting.
The gemstone is from Brazil and has a light blue-green color (but mostly blue). It is clean and bright and has only minor inclusions. The last photo, which was taken outside in sunlight, probably gives a better representation of the actual color of the aquamarine.
The ring at its widest point is approx. 13/16” wide (at the front – top to bottom) and the band is approx. 1/8” at the back.
