Art deco sapphire bracelet calibre

Art deco bracelet with calibre-cut sapphires, an emblematic piece of 1920s luxury and geometry, showcasing custom-cut stones and meticulous craftsmanship.

About this subject

The art deco sapphire calibre bracelet represents the peak of 1920s goldsmithing, a period that exalted straight lines, symmetry and chromatic contrasts. The term calibre refers to a cutting technique where gemstones are shaped exactly to fit the bezel, forming a continuous mosaic with no visible gaps. This approach demanded extreme skill, as each sapphire had to be individually cut to match the geometric design of the metal, usually platinum or white gold.

Sapphires used in such jewelry came primarily from Sri Lanka (then Ceylon), known for intense blue stones, though pink, yellow and green varieties were also employed to create colored patterns. The contrast with baguette or step-cut diamonds was common, emphasizing the linear aesthetic of the art deco movement. This particular bracelet, inspired by a champagne bubbles style, likely refers to filigree or textures reminiscent of effervescence, a touch of lightness within rigid geometry.

Historically, these pieces were commissioned by European and American elites in the 1920s and 1930s, especially after the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes in Paris, which gave the style its name. Today, they are collector’s items, valued not only for their gems but for the rarity of the calibre technique, now nearly extinct due to high cost and complexity. Maintaining such jewelry requires extra care, as bezels can be fragile and calibre stones are difficult to replace without recutting.
