Here is a simple bracelet for your pleasure of carved "New Jade" (Serpentine) flowers interspersed with faceted Brazilian Amethysts. Finished with a heart lobster clasp. You may choose to have a "Hooker" tool included with the bracelet for an additional $10. This is a clever device which allows you to hold the bracelet easily while hooking it. It can also be used to pull a hard-to-reach zipper, etc.
There are some books on Jade and Serpentine listed below. When I searched for "serpentine and jade" on Amazon, I was surprised to see one of my favorite books, Secrets of the Talking Jaguar, so I added it. The quote is, "Fondling an opaline bead I'd found earlier in the day, I decided to give it back to the immensity from where it had come, in hopes that the healing powers of this delicious place might look upon me kindly... I didn't know the old Maya liked opals: only jade, amber, serpentine, and so on."
