I am inclined to doubt that most of these beads are ancient, and not Ptolemaic. (2,300 BP.) The larger front beads in particular appear to be made from modern glass colors. The trailed tapered bead on the left has an "arcade" pattern—though its friend on the right has a feather pattern. The red glass in the prominately seen bead seems to be too bright to be ancient.

Thanks Jamey, that's what I thought. I think it's a mix - some of the smaller ones seem old, but others much less so. I don't think any of the reddish beads are glass though - the one in front is agate, and has those little circular scars old stone sometimes shows. Still a very satisfying necklace to wear.
