This is a beautiful 3-stone 18k solid gold ring. The design is an interpretation of Balinese work with detailed granulation and double rows of twisted wire.
The center stone is a shield-cut cabochon of gem silica from the Ray mine in Arizona. It has deep blue color and is top-grade pure silica. The accent stones are pillowy triangles of pale-violet Holly Blue.
The ring at its widest point is approx. 1/2” wide (at the front) and the band tapers to approx. 3/16” at the back. This is considered a wide-band ring so you might consider sizing based on rings you wear that are comparable.
