This ring is a solid sterling silver version of the leaf of the Ginkgo Biloba tree, hand-carved in wax before being cast in silver. The stem of the leaf wraps around the finger and therefore the ring can be slightly adjusted by the wearer, although  the ring will of course be made to your desired size upon purchasing.
This is a beautiful delicate piece, inspired by a unique species that has appeared in art, culture and medicine across Asia for centuries and has existed as a species in its native China for the last 250 million years.
