18K (750) yellow gold bracelet with a snake design, the head adorned with a quadrangular sapphire, set with rose-cut diamonds, the eyes set with rubies. Early 20th century work. Dimensions: 68 x 0.9 cm. Gross weight: 52.4 g (deformations, scratches) The armour has been known since Antiquity, among the Romans for example, where it was considered an emblem of military bravery and offered as an honorary gift. The armour is distinguished from the bracelet because it is worn high on the arm and is in the form of a spiral, often serpentine, which can be easily adapted. The snake was taken up much later and was very fashionable in the 19th and early 20th centuries. The bracelet that we propose represents a technical tour de force challenging the flexibility of a pattern to the resistance of use.
