Close-ups of our charms:

The outer charms are the same:
ankh, feather of Ma'at, round with musical notes......and desert scene, musical treble clef, the other ankh.
From fourth to tenth spot for me, we have:
silver lily, sewing machine, ruler, artist's palette, Tyet, the other lily, tea pot
Julia's tea pot charm is in fourth place, then eight-petaled flower, tyet in fifth spot (rather than eighth spot), tree of life (reflecting her genealogy studies), lily, nine-pointed rosette, and in tenth spot, a Mensa symbol, reflecting her membership.

There's a bit of a mystery involved. I could find only twelve of her thirteen charms. I thought I'd remembered buying thirteen, back in 2020. But I couldn't remember what the thirteenth one was. I positioned the twelve I had and then saw a need for a round floral shape to balance the nine-pointed rosette on the other side. I remembered I'd bought a charm years ago, possibly twenty, twenty five years ago, at some fair, a small flower charm. I'd worn it very rarely, but remembered it as being of a harmonious shape. It's a bit larger than the rosette, but close enough, as I'd not likely find any better online.

So in it went! Julia said it was perfect, as eight pointed flower had always been a shape that intrigued her. So I figured it was meant to be. I bought it then, "for now".

In my written notes ennumerating the charms, I came across what the thirteenth charm had been. I noted a tiny replica of a Greek coin, to represent Julia's interest in ancient coins. Having read that, I do remember receiving such a thing. But it went awol. And maybe it was meant to. I vaguely remember the eight pointed flower has some symbolic meaning, of a spiritual nature, to speak of a spiritual "blooming". Possibly it confers more of a blessing than a more materially minded coin would have.

In any case, it seems perfectly placed.
