This early Art Deco diamond engagement ring originates from circa 1920. The piece is crafted from silver-toned platinum and is styled as a classic solitaire mount holding a single round old European cut diamond. The central stone is held securely within a six-claw setting accompanied by intricate detailing in the gallery and pierced shoulders. The slim shank has a D-shaped profile with a polished finish and small decorative stepped mouldings near the shoulders. The diamond measures 6.91 by 6.99 mm and sits 5.85 mm above the finger, with the entire piece weighing 2.97 grams. In a contemporary home, this fine piece serves as a traditional engagement ring or a dress ring for daily wear on the hand. The timeless silhouette pairs easily with other fine jewellery items, fitting comfortably into modern wardrobes as a treasured accessory. The durable platinum band provides a secure foundation for the glittering diamond, maintaining a sleek profile suitable for regular personal adornment.

FAQs

Rings from the 1920s Art Deco era typically feature geometric settings, white metals such as platinum, and hand-cut diamonds like old European or old mine cuts. Design features often include subtle piercing work, geometric shoulders, and claw or bezel mountings.

During the 1920s, platinum became the metal of choice due to its strength and ability to create intricate, delicate mountings. Diamonds were cut by hand, resulting in unique facet patterns with high crowns and open culets.

Authentic period pieces exhibit distinctive hand-faceting, such as a round girdle with a small table and a noticeable open culet at the base of the diamond. Hallmark inspection, metal purity testing, and microscopic examination of wear patterns on the setting also help verify age.

An antique diamond ring pairs well with simple modern metal bands or fine pave-set diamond jewellery. Mixing vintage single-stone rings with contemporary minimalist pieces creates a balanced look that highlights the historic character of the central gem.

Clean the ring using warm water, mild soap, and a soft-bristled brush to remove dust from behind the setting. Professional jewelers should periodically check the security of the claws to prevent stone movement.
