Crux gemmata

A crux gemmata (Latin for: jewelled cross) is a form of cross typical of Early Christian and Early Medieval art, where the cross, or at least its front side, is principally decorated with jewels. In an actual cross, rather than a painted image of one, the reverse side often has engraved images of the Crucifixion of Jesus or other subjects.

Examples in metalwork are the Cross of Justin II (6th century, in the Vatican Museums), the 'crumpled cross' in the Staffordshire Hoard (8th century), the Cross of Lothair (10th century, Aachen Cathedral), the Iberian Cross of the Angels and Victory Cross and the Cross of Cong (1120s?, National Museum of Ireland).

In the Late Antique and Early Medieval periods, many objects of great significance, such as reliquaries, were studded with jewels in a style that in recent centuries has been restricted to crowns and other coronation regalia and small pieces of jewellery. In the case of the cross, such decorative embellishment was especially common, and the jewelled cross is a specific type that was represented in paint, mosaic, carved ivory and other media. The cross very often has splayed ends to its arms, but the proportions of the vertical axis to the horizontal one depends entirely on the needs of the composition, and varies greatly. Pendilia, or hanging jewels or ornaments, may hang from the arms, especially the letters alpha and omega shaped in gold. The motif is first seen in a sarcophagus fragment from the late 4th century; the splayed ends of the arms are present from the earliest examples.
