This serpent has not only zigzaggy teeth, but eyebrows(!) Red garnet eyes glitter, and her body is made of a chain whose shape is echoed in the clasp. The ouroboros - the snake who eats her own tail - is an age-old motif in jewelry and is referenced here cleverly with that same clasp. She must put her tail in her mouth to create the circle, infinity, never beginning and never ending.
