I purchased the Astor Ring and within a short time, 2 of the small stones fell out. I contacted customer service to ask if I could get 2 small stones to glue back in. I was totally surprised when the agent said they would be sending me a brand new ring instead. I did not even have to ship back the defective one. So I received a brand new ring and no stones have fallen out. So my first ring was just defective in some way. This company really stands behind their products and wants customers to be happy. Thank you very much for making the exchange so seamless and easy for the customer! I love my ring!
