I thought I would take the challenge and here is what I would do:
I would use one of my very rustic toggle clasps with a hand stamped pattern that vaguely echoes her pendant

Then I would use some of my porcelain beads to string with it. These are greener than they look in the picture. Toggle clasp and beads are available in my Etsy shop.
And finally I would use this beautiful silk to string the necklace together, perhaps with some chain or leather cord added in---not sure about that yet.
What do you think?
Melissa, this is a fun challenge and good for me to exercise my designing brain!! I look forward to the next one. You can see what the other participants are doing here
