Antique 18ct Yellow Gold & Platinum Old European Cut Diamond Cross-Over Trilogy Ring

A beautifully elegant antique diamond trilogy ring dating to the early 20th century, crafted in rich 18ct yellow gold with platinum-topped diamond settings.

At the centre are three graduated natural old-cut diamonds, each individually set within a fine platinum rub-over setting. The larger central diamond is flanked by two slightly smaller stones, creating a wonderfully balanced arrangement with the soft, distinctive sparkle characteristic of hand-cut antique diamonds.

The flowing cross-over design is particularly attractive, with sweeping yellow gold shoulders curving gracefully around the trio of diamonds. The contrasting platinum settings enhance the brightness of the stones while giving the ring the refined two-tone appearance so characteristic of fine jewellery from this period.

Full of antique charm yet remarkably wearable, this would make a beautiful and distinctive engagement ring, or a wonderful addition to an antique jewellery collection.
