Sold! Blue on Blue Boulder Opal Swirled Band Ring. Size 7 1/2.
Rich royal blues and even aqua ripple across this solid boulder opal from Queensland, Australia that measures at 4.9 carats. I've wrapped it in 18k gold and set it on one of my "swirled" bands in oxidized silver. Dots and circles of silver and gold add accent.
This ring fits like a 7 1/2 and gives the appearance of a wide band, but more comfort due to the open nature of the design.
