The general tendency is towards the rococo, but this type of ornament is here by no means strongly marked. In other directions, however, it is more apparent, and already in the seventeenth century we meet with traces of it in engraved designs for jewellery. The best work of this kind is that of Friedrich Jacob Morisson, a draughtsman and jeweller who worked at Vienna from about 1693 to 1697. He was one of the most popular jewellers of the day, and his plates, which are rich in motives for ornaments in precious stones and fine metal-work, found a wide circulation. They comprise aigrettes, earrings, brooches, pendants, bracelets, rings, étuis, and seals. Other Germans who have left designs in the same style are F. H. Bemmel (1700) of Nuremberg, D. Baumann (1695), Johann Heel (1637-1709), and J. F. Leopold (1700)--all of Augsburg. French designers led European taste in jewellery as in furniture, and published a number of important designs. The most remarkable are those of the master-goldsmith Jean Bourguet of Paris, whose models for earrings, pendants, and clasps, dated 1712 and 1723, are set with large faceted stones, and have their backs chased or enamelled with flower designs. His _Livre de Taille d'Épargne_ with designs for enamel-work published as models for jewellers' apprentices, contains amongst other patterns a series of twelve rings set with large faceted stones; beside each ring is a design for the enamel decoration of its shoulder: "Petits morceaux" he calls them, "de taille d'épargne facile à coppier." Contemporary with Bourguet was Pierre Bourdon, of Coulommiers en Brie, who worked at Paris. His designs, dated 1703, are for seals, scent cases, and watch covers of rococo work, and pendent medallions and miniature frames set with precious stones. Among other Parisian designers are the master-goldsmiths Briceau (1709), and Mondon (_c._ 1730-1760) whose _Livre de Pierreries, Pour la Parure des Dames_ contains patterns for earrings, brooches, and aigrettes set with brilliants, and for enamelled and jewelled watches. Of Italian designs for jewellery set with precious stones in the rococo style we may note those of G. B. Grondoni of Genoa, who worked at Brussels about 1715, Carlo Ciampoli (1710), and D. M. Albini, whose _Disegni moderni di gioiglieri_ were published in 1744.
