All of the ancient beads in the gallery came from the Mediterranean area, Europe and Asia Minor, dating from VI c. B.C. to XI c. A.D. Because they may have traveled far from their place of origin, it is difficult to asses the exact date and provenience even of those found in situ in a scientific excavation with clearly defined stratigraphy. The beads have been researched and attributed in accordance with archaeological reports and studies based on analogies of material, size, shape, techniques of workmanship and iconography.
The authenticity of every bead is guaranteed. At least two dimensions are given for single ancient beads and are listed in millimeters. For necklaces, the overall length is listed in inches and centimeters. As a general rule, the photographs depict the best side of the ancient bead. All beads are intact unless otherwise noted. In some cases, the iridescence is more intricate than the photograph shows.
