5 out of 5 starsThe Necklace was everything I had hoped for and more. Very impressed with the craftsmanship and its unique character. It was purchased as a gift for my daughter (she is a genetic counselor.) She loves it. No issues whatsoever with the shipping. It arrived quickly and in perfect condition.
