This is a beautiful 18k solid gold ring with a large Peruvian blue opal cabochon that almost looks like it is glowing. It is a simple but elegant design with a fine twisted wire surrounding the bezel. The band has two rows of twisted wire around the circumference.
The Peruvian blue opal in this ring has a medium-light powder blue color and is cut into a high-domed cabochon which gives the whole piece a rich look and feel. The stone is has top grade color and is flawless (see link below for more info on this material).
The ring at its widest point is approx. 7/16” wide (at the front – top to bottom) and the band is approx. 1/8” wide at the back. See photo with older U.S. dime for size/scale.
