The most prized stone of modern times is unquestionably the diamond, but in Greco-Roman antiquity dozens of precious stones — such as amethyst, carnelian, and peridot — were used for practical and ornamental purposes. These stones were engraved with impressed designs, a technique known as intaglio, or with raised designs, known as cameo. The value of different stone types lay not only in their color and luster, but also in their hardness and malleability during the carving process. The images engraved on gemstones, along with the method of carving (intaglio or cameo), provide clues for scholars attempting to determine whether they were used as seals, amulets, or decorative jewelry. Designs range from simple, sketch-like motifs to complex tableaux of imperial and divine figures. It is perhaps for this reason that the early twentieth-century scholar Gisela Richter remarked that “the study of Greek and Roman gems is the study of classical art in miniature” (Richter 1920: xvi).

Carved Gemstones as Seals
The most prized stone of modern times is unquestionably the diamond, but in Greco-Roman antiquity dozens of precious stones — such as amethyst, carnelian, and peridot — were used for practical and ornamental purposes. These stones were engraved with impressed designs, a technique known as intaglio, or with raised designs, known as cameo. The value of different stone types lay not only in their color and luster, but also in their hardness and malleability during the carving process. The images engraved on gemstones, along with the method of carving (intaglio or cameo), provide clues for scholars attempting to determine whether they were used as seals, amulets, or decorative jewelry. Designs range from simple, sketch-like motifs to complex tableaux of imperial and divine figures. It is perhaps for this reason that the early twentieth-century scholar Gisela Richter remarked that “the study of Greek and Roman gems is the study of classical art in miniature” (Richter 1920: xvi).
Aside from functioning as signatures, seals could also be used to secure containers, cabinets, or even doorways as a kind of safety “alarm” against intruders. Such practices are alluded to in Aristophanes’ comedy Thesmophoriazusae (line 418 ff.), in which women lament that their husbands have sealed off stores of grain, wine, and oil. Household supplies were also sealed off from enslaved members of the household in both Greece and Rome. In one of his letters, the Roman poet Horace describes how his neighbor does not become upset when he discovers a broken seal on his wine jars (Ep. II.ii.132 ff.).
Carved Gemstones as Amulets
Like many objects from antiquity, gemstones could be imbued with properties believed to heal or protect. A jasper intaglio from the Roman imperial period (Figure 3), depicting Harpocrates — the Greco-Roman form of the Egyptian god Horus — was likely used for healing and protection. As the child of the goddess Isis, Harpocrates could be invoked as a protector of children. The child-god sits on a raised lotus and is surrounded by Greek letters that appear to have little meaning beyond, perhaps, a reference to the name “IAO.” Could this be the name of the child whom Harpocrates protects?
The reverse side of the amulet is even more mysterious. It bears additional Greek letters that form a palindrome: ABLANATHANALBA. The same palindrome appears on a number of other objects and papyri associated with magical practices and likely functioned as an incantation.

Not only the image, but also the stone itself, could provide a curative or apotropaic function to its owner. Pliny the Elder provides a lengthy list of the magical and curative properties of different stones in Book 37 of his Natural History. In discussing green gemstones such as jasper (classified as a type of emerald, or smaragdus), Pliny claims that their color refreshes the eyes and relieves fatigue (Nat. Hist. 37.62–64).
Cameo Gemstones
Textual attestations of gemstone use are largely confined to public or religious contexts. After the conquests of Alexander the Great, gemstones from the East became increasingly popular in private settings and appeared in a variety of luxury objects, including vases, drinking vessels, and jewelry. A particularly popular form of gemstone carving was the cameo, in which the design is raised above the gemstone surface. Multi-colored gemstones were especially prized for this purpose because their alternating bands could be used to create striking bichromatic designs.

The Gemma Augustea is one of the finest surviving examples of the cameo technique (Figure 4). It is carved from sardonyx, a type of banded agate, and was likely produced by Dioscurides, the famous gem cutter employed by the family of Emperor Augustus. The stone is divided into two horizontal registers. The upper register depicts the apotheosis of Rome’s first emperor, while the lower shows Roman soldiers raising a trophy in celebration of victory over Rome’s enemies, who cower beneath them. The positive representation of the imperial family in this cameo reflects the visual language that would define later Roman imperial dynasties for centuries.
Ornamental Gemstones – Quality and Control

Most carved gemstones — especially intaglios — that survive are much smaller than the Gemma Augustea and were commonly set into rings or pendants. The combination of precious stones with precious metals became even more visually appealing through the addition of ornamental designs. For those unable to afford the finest materials or craftsmanship, cheaper substitutes could be used to achieve a similar effect.
Figure 5 depicts one such example. The gold setting of the ring has been somewhat crudely hammered around a cameo made of glass in imitation of a precious stone. Although the wear and cracking are understandable given the ring’s age, the craftsmanship falls short of many surviving examples of this type.
Inferior materials and workmanship in ornamental jewelry may reflect the purchaser’s wealth, but they could also result from ancient legislation. The Romans are especially well known for their Republican-era sumptuary laws, which regulated the amount, quality, and type of bodily ornamentation permitted among the upper classes. One such law was the Lex Oppia (215 BCE), which restricted the amount of wealth Roman women could possess and regulated aspects of their dress (cf. Livy, Ab Urbe Condita, Book 34). Under such legislative measures, jewelry was not always a straightforward reflection of wealth or status. At certain periods, ornamentation of lesser quality — iron instead of gold, or glass instead of gemstones — may have been necessary to avoid unwanted attention from authorities.

The Cultural Facets of Carved Gemstones
Civilizations of the eastern Mediterranean were among the first to develop seal rings through intaglio carving techniques. Many gemstones in these rings were engraved with scarabs on one side and Egyptian deities or symbols on the other, often mounted within swivel bezels — a form known as early as the second millennium BCE. This tradition survives in scarab rings such as the one shown in Figure 6, which dates to fifth-century BCE Cyprus. Comparative material such as this demonstrates that the use of seal rings in Greco-Roman antiquity was heavily influenced by cultural traditions from West Asia and ancient Egypt, where such objects already served a variety of functions.
The multiple uses of carved gemstones described above testify to the complex ways ancient societies engaged with material culture. The perceived magical properties of gemstones and their imagery remind us that religious belief permeated many aspects of daily life in antiquity. Both the carved image and the stone itself could carry symbolic meanings and practical functions that helped ancient peoples navigate concerns surrounding health, marriage, protection, and death.
Over time, new forms of jewelry emerged to meet the social and political needs of ruling families, especially in imperial Rome. In addition to the Gemma Augustea, many gemstones from the Julio-Claudian dynasty depict members of the imperial household in much the same way as contemporary coinage. Unlike coins, however, personal ornaments bearing the recognizable image of a revered emperor or empress could communicate political allegiance within elite Roman social circles.
Although the practice of carving gemstones has largely fallen out of fashion today, their history raises enduring questions about what jewelry — beyond simple ornamentation — continues to accomplish culturally for its wearer.
