First introduced in 1962, Jean Schlumberger’s vitreous enamel masterpieces are among the most revered jewellery designs of all time. The 19th-century enamel art form is a complex, labour-intensive process of meticulously layering and firing enamel multiple times. For his signature vitreous pieces, enamel is made by heat-fusing powdered glass to a metal surface, creating rich hues with extraordinary clarity and a smooth finish. Few craftspeople in the world have the artistry and skill to execute these time-honoured techniques. A piece of design history, Jean Schlumberger’s magnificent enamel bracelets are beautifully accented with gold.
