These were found in Saint Denis, first decade 6th century. The garnet cloisonne was starting to disappear by this time. I don’t know the context of these appliques or which grave they came from. My book on the Saint Denis finds has gone walk about. Please post in the comments if you know. I guesstimate that these were belt fittings, but could be wrong. The center square appears to be turquoise ENAMEL OR GLASS.
