Everyone at White flash was very helpful. I went to them to buy an engagement ring. I had never bought diamond jewelry before and they were very helpful. I had been to several other places (Jarrod, Bailey Banks and Biddle, and a couple other places) to look at diamonds. No other diamonds compared to the quality at White Flash. The clarity and cut of their princess cut were unmatched. I knew quickly upon seeing a few diamonds that I would buy from them. Their customer service only added to the already great experience.
Also, they seem to actually care about the conflict diamond situation. They have lots of info online for you to read. More than that the employees are actually knowledgeable about it, which is not the case many other places where they simply hand you a generic brochure that was probably produced 15 years ago.
I suppose I should add that I live in Houston and actually went to their brick and mortar store. All of the diamonds from their website are there at the store. If you live nearby I highly recommend you going into the store.
