Symbols of wisdom and good luck, Hawaiian sea turtles (honu) are interpreted in sterling silver by San Diego jewelry artist David Leight. Each is set with a blue optical glass crystal that glows against your skin and changes colors in the light. The unique iridescence is created by the same NASA technology used to reflect and deflect light on heat shields. The effect is magical. ¾" wide earrings hang 1½" on sterling leverbacks. 1 1/8" pendant with movable head and limbs arrives on an 18" sterling cable chain. Made in USA. Sold separately.
