Exquisite antique Art Nouveau era French cameo glass perfume bottle by Burgun, Schverer & Cie (B.S. & Cie). Circa 1897-1903. Featuring a slender neck terminating to a bulbous form. Cameo acid etched cut back, composed of clear glass, the interior frosted with milky-opaque finish, the exterior with violet overlay. Wheel etched with stylized bluebell flowers complete with open blossoms, and undulating stems and leaves cut in relief on a mostly martelé ground. The glass is further hand embellished partly in gilt accents. The cameo glass body is marked with hand painted gilt letters B.S. & Cie just above the silver base. Mounted with sterling silver collar and and stepped pedestal foot base. Complete with matching silver stopper. The collar features a repeating pattern of stylized leaves and tendrils wrought in an Art Nouveau manner. The silver stopper, all of one piece, is dome shaped and has a repeating pattern of flowers along its base, its plug is silver, rather than glass. Silver mounts are enhanced in gold vermeil finish. Hallmarked on the collar and base with the French Minerve 1st standard mark, in use from 1838, which depicts the goddess Minerva with a number 1 beside her denoting a silver content of .950/1000 (of 95% silver and a higher grade of finesse than the .925 standard for sterling silver). Hallmarked on the stopper with the French head of the wild boar, to denote a silver content of at least .800/1000 silver. Bearing a silversmith's mark, appears to be for Marie Chomel, Veuve (widow), who used an MCV with an image of a coffeepot in the center from 1898 to 1904, which fits in with the age of the glass bottle. The bottle stands a total height of 4 5/8" and 2 3/4" wide. No chips or cracks to the glass, some wear to the gilt decoration on the glass and to the gilt vermeil finish on the silver. Overall in good to excellent condition and presents very well.
