Vintage 1971 Natural Australian Opal & Diamond 18ct Gold Oval Cluster Ring

A beautifully unique 1970s vintage opal and diamond cluster ring, centred around an oval cabochon natural Australian opal weighing approximately 0.67 carats. The opal displays a soft, glowing body colour with flashes of vibrant blues and greens that shift beautifully with the light. Surrounding the centre stone is a halo of twelve round-cut diamonds, adding a gentle sparkle that perfectly complements the opal’s ethereal play-of-colour. Crafted in 18ct yellow gold with a platinum topped setting, the design offers a lovely contrast that enhances both brilliance and warmth. Hallmarked in Birmingham 1971, this is a timeless and feminine piece with classic vintage charm. Elegant and full of character, it would make a beautiful alternative engagement ring or a meaningful everyday treasure.
