I love this One of a Kind Spirit Lock. It is made from a necklace I call the Sapphire silver circus train. It is a silly name I know. I have included natural rubies, sapphires, turquoise, apple coral, labradorite, amethyst, carnelian and spiny oyster shell. The spirit lock is from the Hmong tribe of Northern Thailand. It measures 19 inches with 2 inch extender chain.
