The ring was lovely, but was too big for my wife so it had to be returned...and two weeks later I am still waiting for a refund!

Great support on the phone. Really helpful trying to find the right size ring from various stores. Excellent overnight shipping. I appreciated that you could look up what size ring I needed to buy! My wife thinks it's a beautiful Christmas present.

Flawless from beginning to end. I had some questions on the product and they were answered quickly and knowledgeably. Will be my first call for jewellery purchases from now on. Such a stunning product. The unusual shape emphasises the stunning diamond pave. I bought as a special occasion ring but I have yet to take it off.
