This ouroboros snake charm necklace speaks to the cyclic nature of the universe; that creation begins after destruction, and life springs forth from death. It is humanity's never ending story, and our place within it. A powerful symbol of endless return, the ouroboros - or the snake eating its own tail - gives us all hope. Carry this powerful charm necklace in your jewelry collection as a reminder that life is a never ending story. Silver version comes on a simple sterling silver 18" cable chain with a spring ring clasp, adjustable to 16". The charm measures 21x21mm, excluding jumprings. Gold tone version features a bronze charm on an 18" gold-filled chain and is not adjustable. · Available in Sterling Silver & Bronze • Lipped necklace cards come free with every order.
