Hi, many thanks for your detailed reply, so helpful!

I love the pieces you've chosen, we have very similar taste. For small, medium, and large amulets, I'd likely choose the same ones, and so fun to have one of each size. So, I say yes to diversification!
Ah, so interesting about the medium Sea Star amulet. I've considered that one too, but also was concerned it might be a less ideal size for the design. So, I'd come to the same conclusion that I'd likely prefer the large.
Regarding the leather cords, the blue one does look beautiful with the amulet. It so nicely complements the stone colors.
So fun to hear the amulet is even more gorgeous in person. I think it's hard to capture the beauty of moonstones in photos, and the starfish design is so beautiful and creative. I've been enamored with it for quite a while! The other I'm considering is the large Blue Moon amulet, link below. It's a more spare, simple design, but I also love it. But, I think for the large size I may prefer more detail. Ideally, I'll be able see both together to decide.
