WF is great. You will not be disappointed.
I can definitely recommend Whiteflash. The quality of the diamond is exceptional. They have thousands of diamonds and the website is very easy to use. The filtering system is the best of any of the online retailers and I was easily able to narrow my search. Having worked at a jewelry store in the past, I was slightly obsessed about the quality of the stone. When I used the chat feature, the CEO personally responded and put me in touch with my diamond consultant the next day, who helped with the final selection and worked with me to find the perfect setting. The customer service was phenomenal. WF shipped the ring within a week of receipt of payment and ensured it arrived on time right before New Year's Eve. My finance absolutely loves the ring. It exceeded her and my expectations. WF is great. You will not be disappointed.
