Late Art Deco Australian Opal and Old-Cut Diamond Ring (2.55cts)

Dating to the late 1930s, this elegant vintage ring centred with a natural Australian opal, cut as an oval cabochon and displaying a luminous, ocean-like play of colour, with drifting greens and soft pastel flashes that shift beautifully as the light moves.

The opal is claw-set in a finely crafted setting designed for strength and durability, while the ring features a polished shank that creates a clean and elegant appearance. Four old-cut diamonds (two larger and two smaller) are set into the shoulders, adding subtle sparkle and enhancing the refined, symmetrical design. This classic construction is typical of fine vintage jewellery, offering both practicality and visual balance.

Graceful and understated, this ring is a timeless piece, well suited to everyday wear or as a distinctive vintage statement.
