I really love the design and hope you do too. The little leaves are Garnet and the focal bead is a seed. I was told it was a coconut seed but I'm not sure ...
My description of the necklace was -
The seed sprouts, the tree grows, bears buds, leaves and fruit. The chain of life continues, the decaying skeletal leaf provides nutrients for the seed which sprouts, the tree grows ....
I'd like to do something similar in real gold rather than artistic wire but at the moment can't afford it.
