Antique 1930s 14K black opal and old mine cut diamond halo ring

A stunning Lightning Ridge black opal ring with an old mine cut diamond halo. Black opals are much rarer than white opals and their color play is robust. Flashing patches of color are more distinct when they appear out of a dark background, as they do in black opals like this one. The oval cabochon opal (approx. 1.65 cts) shows an impressive play of light with large swaths of green and blue pulsing across the stone. A closer look at different angles reveals rich violet, peach, pink and orange tones. The opal is framed by a dozen old mine cut diamonds, approx. 1.44 ctw, neatly set and twinkling with warmth.
