The most insanely stunning Australian Boulder Opal. The host rock is a light tan swirled with cocoa brown, with creamy opal inclusions that have fiery blue and green flash throughout, the center section has dark blue flash. The back of this ring has an open setting so that you can view the underside of the stone, which resembles a gorgeous abalone shell with flashes of blue, green and purple throughout.

Set in Sterling silver with a round wrench shank, size 8.25. The stone measures 15 mm wide by 19 mm tall. (Measures right at an 8.25, but the flat back of the setting makes it a generous fit a little closer to an 8.5)
