Beads
The beads in this necklace make an attractive pattern, but originally, the golden and carnelian beads might have stood alone, in the Middle Kingdom, with the glass beads only being added to the mix in Roman times, or even later.
It was not uncommon for beads to be reused at various time periods in Ancient Egypt. It is entirely possible that some lucky citizen of the Fayum rejoiced in this necklace, though it is, alas, equally possible that the beads originally made two or even three different pieces of jewelry, joined together after the beads arrived in the Museum.
