This is a mixed metal ring with an 18k gold setting and decorative items with a solid Sterling silver band. The gemstone is a beautiful Peruvian blue opal with saturated medium-blue color. The stone is some of the best of this material as it is free from inclusions that are commonly found in blue opal.
The design of the ring includes a single row of gold balls around the setting that is bookended by a triplet of gold balls on either side. The band has a hammered finish but is smooth and comfortable to wear.
The ring at its widest point is just under 7/16” wide (at the front – measured top to bottom) and the band is approx. 1/4” wide at the back (see photos with older U.S. silver dime for size/scale).
