I have purchased at least 30 of these necklaces. I have NEVER been disappointed. I take a shower, go in the pool the beach leaving my necklace on. Never tarnishes. The quality is exceptional. I bought them for my daughter, nieces, friends, daughters' friends, and they now buy for their friends and family. I literally think of people to buy them for. They are the perfect gift. I can't say enough good things about this company. if you don't have one buy one and if you do buy more.
