Fine white gold filagree holds an outstanding opal that displays a wide play of color--red, green, blue and lavender.
The opal itself measures 3/4 inch by 1/2 inch. It was not removed from the mounting to assure it remained in perfect condition. Therefore, we were unable to get an accurate weight in carats for the stone. The opal is highlighted on each end by small faceted emeralds. Overall, the ring top measures 1 inch by 1/2 inch and weighs 6.1 grams.
The design is unique--one we have never seen before. In natural light the opal has a remarkable range of color. The stone is held in the mounting by an unusual use of prongs--doubles on both the long and short sides of the stone.
