This bracelet was purchased by the donor from the reknowned Parisian jeweller Frédéric Boucheron (1830-1902). Boucheron gathered around him a team of fine designers and craftsmen to execute his work. Charles Riffault revived the technique of translucent or unbacked cloisonne enamelling, which he patented, but granted the monopoly of the process to Boucheron. From about 1864, Riffault executed enamels in this manner for Boucheron, who exhibited them at the International Exhiibtion in1867 and 1878.
