18ct White Gold Sapphire & Diamond Cluster Ring - French

1900 - 1920
Description

A truly beautiful antique ring set with a cushion shaped sapphire displaying rich mid to deep blue tones, held within a smooth rub-over setting. Surrounding the centre stone, a cluster of ten old mine cut diamonds forms a soft scalloped border, giving the piece a delicate and refined presence.

Though made in the early Art Deco period, the design carries strong Belle Époque influence, seen in the flowing lines and open tapered gallery. Crafted with a platinum setting and white gold shank, it is a fine example of thoughtful design and quality workmanship from the era.

Part of our antique sapphire ring collection.

Why Sellingantiques dated this piece to THE 1920s:
Old-cut diamonds in the surround: hand-faceted stones cut before modern uniform brilliants.
Hand-pierced open gallery under the cluster: fine early twentieth-century jewellery construction.
Millegrain beading along the sapphire border: hand-applied decorative rolling to the collet edge.
Platinum setting on a gold band: two-metal construction favoured during the nineteen-twenties.

This early Art Deco ring exhibits French origins from the 1920 period, composed of 18ct white gold and platinum. The central cushion cut sapphire displays rich mid to deep blue tones, held within a smooth rub-over setting. A cluster of ten old mine cut diamonds surrounds the centre stone in a soft scalloped border, enhanced by millgrain detailing and an open tapered gallery. The smooth silver-toned shank shows light surface wear consistent with age, alongside worn French owl and mascaron hallmarks indicating gold and platinum content. Measuring 14 mm by 12.5 mm across the face with a weight of 3.15 grams, this piece suits everyday wear on a finger. It functions as a fine item of personal jewellery for modern use, pairing easily with other precious accessories or serving as an individual statement piece.

FAQs

French Art Deco cluster rings typically feature clean geometric arrangements, fine millgrain border details, low-profile bezel settings, and a central coloured gemstone, such as a sapphire, bordered by diamonds.

These rings are commonly crafted from 18ct white gold, yellow gold, or platinum, set with natural blue sapphires and old-cut diamonds.

Authentic French pieces feature specific hallmarks, such as the eagle head for 18ct gold or the dog head for platinum, along with distinctive hand-finished millgrain work and rub-over settings.

A cluster ring functions as a standalone statement piece or can be paired alongside simple white gold or platinum bands to highlight its central motif.

Clean gently using warm water, mild soap, and a soft-bristled brush. Avoid harsh chemicals and store separately to protect the metal and settings from scratches.
