A beautiful and distinctive antique sapphire and diamond crossover ring, crafted in solid 18ct yellow gold with contrasting platinum gemstone settings. Dating to approximately the 1920s–1940s, this is a particularly charming example of traditional fine jewellery, combining a richly coloured natural blue sapphire with sparkling original old-cut diamonds and elegant period craftsmanship.
At the centre sits a stunning natural sapphire, weighing approximately 0.50 carats and displaying a wonderfully rich, deep blue hue. The gemstone is particularly well cut, with excellent proportions that beautifully showcase its natural colour and brilliance. This is a genuine natural sapphire rather than a synthetic stone, adding to the quality and appeal of the piece.
The central sapphire is beautifully framed within a traditional rub-over bezel setting, finished with delicate milgrain edging. This finely textured decorative border adds an elegant vintage character to the design, while securely protecting the gemstone within its setting.
Complementing the sapphire are original natural old-cut diamonds, individually mounted within contrasting platinum rub-over settings. These charming antique diamonds retain the distinctive faceting and individual character associated with traditional diamond cutting, producing beautiful flashes of sparkle against the warm yellow gold.
The gemstones are arranged within an attractive crossover design, with the gold shoulders flowing elegantly around the settings to create a beautifully balanced composition. The combination of yellow gold and platinum is particularly characteristic of fine jewellery from the early 20th century, offering a wonderful contrast between the rich gold shank and bright white diamond settings.
Crafted in solid 18ct yellow gold, the ring is marked 18ct to the shank, with its precious metal content additionally confirmed through professional XRF testing.
Weighing approximately 3.4 grams and measuring a UK ring size M, this is a beautifully proportioned antique ring, offering excellent gemstone presence while retaining a comfortable and elegant feel when worn.
A wonderful original period piece, combining the captivating colour of natural sapphire, the individual charm of antique old-cut diamonds and the timeless appeal of traditional precious metal craftsmanship.
