Edwardian Black Opal & Diamond 18ct Gold Platinum Cluster Ring

An exceptional Edwardian Australian black opal and diamond cluster ring, centred with a natural solid black opal weighing approximately 1.32 carats. The opal displays a mesmerising play of colour, with vivid flashes of electric green and cobalt blue dancing across a dark body tone, creating remarkable depth and intensity. Surrounding the opal is a scalloped halo of sixteen bright diamonds, adding elegant sparkle and beautifully framing the vibrant centre stone. Dating to circa 1910, the ring is crafted in 18ct gold with platinum settings, a hallmark of fine Edwardian jewellery. Delicate openwork scroll shoulders provide beautiful detail from every angle, while the platinum-topped cluster enhances the refined craftsmanship of the period. The combination of a highly colourful black opal, antique diamonds and intricate Edwardian design makes this a particularly rare and captivating piece, equally suited as a statement ring or an alternative engagement ring.
