It is absolutely beautiful!!!

I received the diamond on Friday. It is absolutely beautiful!!! I don''t know if Kathy(?) explained but I was originally looking at Eightstar diamonds at my local jeweler. I knew of Whiteflash obviously and I wanted to compare your ACA with the 8*. So I took the diamond into my jeweler and honestly I could not tell the difference between the two (except for the price!). I ordered the .708 because it most closely resembled the 8* that my dealer got in for me. However I actually would like a larger diamond, hopefully around 1ct, maybe slightly larger. So I would like to return this diamond and start looking for the real one! Can you give me an RMA number for it please and explain what I have to do? Thanks Katie!
