Byzantine artisans were famous in both the East and the West for what is known today as "cold cloisonné," a method by which gems, semi-precious stones and glass were attached in decorative patterns to a metal surface. This medallion is a fine example that clearly demonstrates the technique used by Byzantine goldsmiths and jewelers. The term "cloisonné" is derived from the French word for "cell." In cold cloisonné, a framework made of metal filigree or wire, creating pockets in decorative patterns into which the decorative stones are fitted. The edges of the "cells" are then turned over to hold the stones firmly in place.

In this piece, garnets, lapis lazuli, and red- and green-colored glass are combined into a colorful pattern on the gold filigree. The filigree work is very finely achieved, with gold wire carefully twisted into strands resembling rope to separate the different concentric sections of the medallion. The medallion is also a testament to the trade networks Byzantium had established with Asian kingdoms to east. The garnets were probably obtained from India, while Sogdiana was the nearest source for the blue lapis stones.
