Antique Art Deco 18ct Gold & Platinum Old Cut Diamond Solitaire Ring

A timeless Art Deco diamond solitaire ring, beautifully crafted in solid 18ct yellow gold with a platinum setting, showcasing a bright natural old-cut diamond with exceptional fire and character. Elegant and understated, this classic antique ring perfectly captures the refined craftsmanship and enduring style of the Art Deco period.

The old-cut diamond measures approximately 5mm in diameter, giving an estimated weight of around 0.50ct. It displays excellent brilliance with the distinctive broad flashes of light and lively sparkle that make antique-cut diamonds so highly sought after. In natural light, the stone comes alive with beautiful fire and a warmth that is uniquely characteristic of old-cut diamonds.

The diamond is securely claw set in platinum, with beautifully sculpted platinum shoulders flowing seamlessly into the 18ct yellow gold band. The combination of platinum and gold was a hallmark of fine early 20th-century jewellery, offering both strength and an elegant contrast that remains as appealing today as when it was first made.

A timeless antique solitaire, perfect as an engagement ring or as a treasured addition to any fine antique jewellery collection.
