The Italians certainly succeeded in performing feats of lapidary art at a later period. Vasari mentions two cups ordered by Duke Cosmo, one cut out of a piece of lapis lazuli, and the other from an enormous heliotrope, and a crystal galley with gold rigging was made by the Sanachi brothers. In the Green Vaults in Dresden may be seen numerous specimens of valuable but hideous products of this class. In the seventeenth century, the art had run its course, and gave place to a taste for cameos, which in its turn was run into the ground.
Cameo-cutting and gem engraving has always been accomplished partly by means of a drill; the deepest point to be reached in the cutting would be punctured first, and then the surfaces cut, chipped, and ground away until the desired level was attained. This is on much the same principle as that adopted by marble cutters to-day.
Mr. Cyril Davenport's definition of a cameo is quite satisfactory: "A small sculpture executed in low relief upon some substance precious either for its beauty, rarity, or hardness." Cameos are usually cut in onyx, the different layers and stratifications of colour being cut away at different depths, so that the sculpture appears to be rendered in one colour on another, and sometimes three or four layers are recognized, so that a shaded effect is obtained. Certain pearly shells are sometimes used for cameo cutting; these were popular in Italy in the fifteenth century. In Greece and Rome the art of cameo cutting was brought to astonishing perfection, the sardonyx being frequently used, and often cut in five different coloured layers. An enormous antique cameo, measuring over nine inches across, may be seen in Vienna; it represents the Apotheosis of Augustus, and the scene is cut in two rows of spirited figures. It dates from the first century A. D. It is in dark brown and white.
Among the treasures of the art-loving Henry III. was a "great cameo," in a golden case; it was worth two hundred pounds. This cameo was supposed to compete with a celebrated work at Ste. Chapelle in Paris, which had been brought by Emperor Baldwin II. from Constantinople.

In Paris was a flourishing guild, the "Lapidaries, Jewel Cutters, and Engravers of Cameos and Hard Stones," in the thirteenth century; glass cutters were included in this body for a time, but after 1584 the revised laws did not permit of any imitative work, so glass cutters were no longer allowed to join the society. The French work was rather coarse compared with the classic examples.
The celebrated Portland Vase is a glass cameo, of enormous proportions, and a work of the first century, in blue and white. There is a quaint legend connected with the famous stone cameo known as the Vase of St. Martin, which is as follows: when St. Martin visited the Martyr's Field at Agaune, he prayed for some time, and then stuck his knife into the ground, and was excusably astonished at seeing blood flow forth. Recognizing at once that he was in the presence of the miraculous (which was almost second nature to mediæval saints), he began sedulously to collect the precious fluid in a couple of receptacles with which he had had the foresight to provide himself. The two vases, however, were soon filled, and yet the mystical ruby spring continued. At his wit's ends, he prayed again for guidance, and presently an angel descended, with a vase of fine cameo workmanship, in which the remainder of the sacred fluid was preserved. This vase is an onyx, beautifully cut, with fine figures, and is over eight inches high, mounted at foot and collar with Byzantine gold and jewelled work. The subject appears to be an episode during the Siege of Troy,—a whimsical selection of design for an angel.
Some apparently mediæval cameos are in reality antiques recut with Christian characters. A Hercules could easily be turned into a David, while Perseus and Medusa could be transformed quickly into a David and Goliath. There are two examples of cameos of the Virgin which had commenced their careers, one as a Leda, and the other as Venus! While a St. John had originally figured as Jupiter with his eagle!
In the Renaissance there was great revival of all branches of gem cutting, and cameos began to improve, and to resemble once more their classical ancestors. Indeed, their resemblance was rather academic, and there was little originality in design. Like most of the Renaissance arts, it was a reversion instead of a new creation. Technically, however, the work was a triumph. The craftsmen were not satisfied until they had quite outdone the ancients, and they felt obliged to increase the depth of the cutting, in order to show how cleverly they could coerce the material; they even under-cut in some cases. During the Medicean period of Italian art, cameos were cut in most fantastic forms; sometimes a negro head would be introduced simply to exhibit a dark stratum in the onyx, and was quite without beauty. One of the Florentine lapidaries was known as Giovanni of the Carnelians, and another as Domenico of the Cameos. This latter carved a portrait of Ludovico il Moro on a red balas ruby, in intaglio. Nicolo Avanzi is reported as having carved a lapis lazuli "three fingers broad" into the scene of the Nativity. Matteo dal Nassaro, a son of a shoemaker in Verona, developed extraordinary talent in gem cutting.
An exotic production is a crucifix cut in a blood-stone by Matteo del Nassaro, where the artist has so utilized the possibilities of this stone that he has made the red patches to come in suitable places to portray drops of blood. Matteo worked also in Paris, in 1531, where he formed a school and craft shop, and where he was afterwards made Engraver of the Mint.
