Cushion-cut natural sapphire: cut style widely used in early twentieth-century jewellery.
Eight-cut shoulder diamonds: faceted cut favoured during the 1920s and 1930s.
Fine millegrain beading along the shoulders: delicate hand-finished detail of the period.
Slender tapering yellow gold mount: proportions and profile typical of 1920s solitaires.

Every single antique dealer on our platform is individually approved by our internal team. We verify their professional trade history, ethical standards, and photographic quality to ensure a secure, high-standard buying environment. Upon joining, every dealer agrees to a strict 9-point code of conduct. While issues can occasionally arise, our dealers typically resolve them swiftly and directly with the buyer. In fact, since our founding in 2002, Sellingantiques has only had to step in to help resolve an issue on roughly five occasions—a true testament to the quality of our dealers and their dedication to your happiness.

Secure Transit

Our dealers are highly experienced in packing and shipping fragile, high-value antiques. Because you are in direct contact with the dealer, you will be able to easily go through all available shipping and insurance options together to ensure your item arrives safely.

The Sustainable Choice

Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

An Art Deco solitaire ring from circa 1920, fashioned in 18k yellow gold with a central blue cushion-cut sapphire secured in a four-claw setting. The mounting includes slim, tapered shoulders set with small eight-cut accent diamonds, complemented by millgrain detailing along the edges of the metalwork and a smooth, slender shank. The sapphire weighs 0.44 carat, and the total diamond weight is approximately 0.08 carat, producing a rich royal blue and gold colour palette. The ring sits 4.9mm from the finger, with a central stone measuring approximately 5.0 x 4.3mm. Designed as an alternative to a traditional diamond engagement ring, the piece suits daily wear on a finger as an elegant personal ornament. It fits a UK size O or a US size 7, and is suited for formal or everyday use in contemporary settings. The object functions as a piece of fine jewellery intended for personal adornment.

FAQs

Art Deco jewellery from the 1920s features geometric motifs, clean lines, and vibrant coloured gemstones, often set in platinum or yellow gold settings.

Art Deco solitaire rings typically utilise yellow gold or platinum bands to secure natural gemstones such as sapphires, emeralds, or diamonds with claw or bezel settings.

Authentic Art Deco pieces demonstrate hand-finished detailing, fine grain settings, historic hallmarks, and era-appropriate stone cuts without modern laser facets.

A vintage sapphire solitaire pairs effortlessly with minimalist daily wardrobe choices or acts as a subtle blue focal point alongside contemporary fine gold jewellery.

Clean the ring gently using warm water, mild liquid detergent, and a soft-bristled brush, avoiding harsh chemical cleaners or ultrasonic baths that may dislodge accent stones.
