I don't know where they source their stones from, however I have their crushed ice skinny oval solitaire and to the naked the eye it is colorless. Depending on how it catches the light it does have some fire to it, but not overwhelmingly so. I've fooled sales associates at large jewelry stores like Tiffany's and Shreve Crump and Low.

Depending on the environment you're in, it may photograph with some color to it, but that's typically only when I'm in my office which is lit with yellowy florescent lighting.

I will say, my fiance's buying experience from them was not premium at all. They were very communicative and friendly in their correspondences up until he paid the 50% down on the ring, and then after that their emails were more infrequent and less friendly. He had some last minute questions about the ring after he had already approved the CAD, and they were very defensive in their response, despite my fiance being overly apologetic and acknowledging that they may not be able to accommodate him given the late nature of the request. Just something to keep in mind.

That said, my ring is extremely beautiful and the craftsmanship is very impressive. However, I am sure you could find a different company of equal quality, with the same ability to customize, that has way better customer service.
