I shared the exact specifications of my Whiteflash diamond with my jeweler to see if he could find something comperable and his response was, ""You should buy that diamond! I cannot even come close to the quality and price. In fact, as a jeweler, I want to buy your diamond."" In addition to an incredible value, Whiteflash provides you with all the information necessary to find the right diamond. The 30 day ACA review period is great, but honestly, unecessary because you have so much information before you guy their ACA diamonds. I felt very confident when I made the purchase, and the diamond is so much more beautiful in person than on the website.
