I'm selling this because it's very sparkly and I love it, but I don't have a chance to wear it. Chain: 316L Top: Swarovski Zirconia / 925 Sterling Silver [Hypoallergenic] This necklace uses pure rhodium, which is generally considered to be less likely to cause allergic reactions. It's a pure rhodium finish that's gentle on those with metal allergies, making it a great choice for everyday wear. [Elegant Sparkle] This pendant features Swarovski zirconia. It has a sparkle like a real diamond. The simple design and sturdy construction of the necklace give it an elegant and sophisticated impression.
