13. Jeweled Gold and Enamel Dress Cane -Ca 1900 -Slightly tapering engine turned and translucent pale pink enameled silver knob embellished with two yellow gold bands set with half pearls and a larger rose cut diamond on the top, closed pored deep black ebony shaft and a metal ferrule. A Russian identity is apparent on the profile of this cane from the glorious Romanov Imperial days and possibly Fabergé. It impresses with its balanced harmony and perfect execution and symbolizes better, than any other, the luxury spirit of the fin de siècle. -H. 1 ¼” x ¾”, O.L. 37 ¼” -For similar pieces authenticated as Fabergé, see the WMFA?Virginia Museum of Fine Arts , Fabergé Collection -$2,000-$3,000 -The industrial revolution brought new technological developments and facilitated engine turning and the production of enameled cane knobs and handles. Engine turning, also often called guilloché, is done with a rose-engine machine or decoration lathe, which cuts grooves in geometric patterns. It was used to adorn the cases of pocket watches and other small items and also to create printing plates for stock and bond certificates. Because the pattern is engraved, the reflection of light is enhanced, and its brilliance can be seen as the pieces are moved at different angles. Engine turning is very delicate and requires sophisticated equipment and high skill. This technique was developed in the 18th century and died out after World War One. -Enamel is a smooth, glassy, protective or decorative medium that can be fused on to a metal, glass or ceramic surface by firing and generally pairs well with engine turning. Enamel colors are made out of powdered glass and pigmented metallic oxides such as gold, copper and manganese suspended in an oily medium. During firing, the oily medium burns away and the others fuse together. In enamelware, colored enamel pastes are applied to a metal body by various techniques and then fired. In basse-taille or low relief enameling, a design is carved on the body and the whole area is covered with one or more layers of translucent enamels. In champlevé enameling, the ground is cut away and the hollows filled with the enamel paste, leaving the raised areas free.
