An elegant Russian rectangular cigarette case with softly rounded corners, crafted in 14-karat gold at the St Petersburg gold and diamond workshop of Beilin & Son. The exterior is decorated with a refined geometric pattern executed in two-tone gold in the Art Nouveau style, realised through exceptionally fine chasing. The rhythmic diagonal lines create a dynamic play of light and underline the high level of surface workmanship characteristic of the finest pre-Revolutionary St Petersburg jewellery. The push-button clasp is set with a natural cabochon-cut sapphire, harmoniously integrated into the overall artistic composition. Distinguished by flawless proportions, precise fitting of components and a pronounced status character, the piece is representative of objects intended for courtly and aristocratic circles.
