A striking 18ct gold ring set with a large oval black opal. Black opals are the most desirable opals. The first recorded black opal was found in Lightning Ridge, Australia in 1873. It is the only place where black opals are sourced. This ring was made circa 1930. It displays green and blue flashes and looks fabulous on the finger. }

A good looking Art Deco ring. It has an 18ct white gold shank and a platinum top. It is set with a large oval shaped black opal which displays predominantly blue and green colours with some red flashes. Black opals, the most valuable of the opal range, contain every colour of the spectrum, from deepest and clearest blues and iridescent greens, through to golden orange, red and fuchsia. Due to their structure, they may contain any combination of an infinite number of patterns and show their greatest brilliance only during flashes of movement. The shoulders have three diamonds on each side. }
