Rare French Canetille Brooch, Circa 1830 – A Monument to Early 19th-Century Grace

An unusually large French brooch dating to circa 1830, showcasing a finely carved male portrait in brown chalcedony, mounted atop a subtly faceted pale agate or quartz base. The jewel’s generous proportions, combined with intricate canetille goldwork and vibrant blue enamel, create a striking neoclassical presence. Likely once the centrepiece of a grander jewel, it was later adapted into a brooch with remarkable finesse. A rare survivor of refined early 19th-century taste — imposing yet intimate, and quietly evocative.
