Apart from these humbler branches of the subject, in the middle of the 19th century the production of jewelry, regarded as a personal art, and not as a commercial and anonymous industry, was almost extinct. Its revival must be associated with the artistic movement which marked the close of that century, and which found emphatic expression in the Paris international exhibition of 1900. For many years before 1895 this industry, though prosperous from the commercial point of view, and always remarkable from that of technical finish, remained stationary as an art. French jewelry rested on its reputation. The traditions were maintained of either the 17th and 18th centuries or the style affected at the close of the second empire--light pierced work and design borrowed from natural flowers. The last type, introduced by Massin, had exercised, indeed, a revolutionary influence on the treatment of jewelry. This clever artist, not less skilful as a craftsman, produced a new _genre_ by copying the grace and lightness of living blossoms, thus introducing a perfectly fresh element into the limited variety of traditional style, and by the use of filigree gold work altering its character and giving it greater elegance. Massin still held the first rank in the exhibition of 1878; he had a marked influence on his contemporaries, and his name will be remembered in the history of the goldsmith's art to designate a style and a period. Throughout these years the craft was exclusively devoted to perfection of workmanship. The utmost finish was aimed at in the mounting and setting of gems; jewelry was, in fact, not so much an art as a high-class industry; individual effort and purpose were absent.
