It's beautiful -- I'm working on getting it set at the moment. One thing I was able to do at the jeweler was to compare it next to a few stones he had in shop. For example, there's a new 126 facet ideal stone that someone is producing that he is very high on. He placed one of these 126 stones with similar traits next to mine under full spectrum light. By comparison, this stone performs just as well as the 126 facet, the only difference being that the 126 reflects a lot of tiny sparkles, where my hearts & arrows reflects very large flashes (obviously due to the number/size of the facets). I was really happy to see that my stone, which cost considerably less than the fancy 126 facet, performed the way it did.
All in all, I'm very happy with the stone and very impressed with the hearts & arrows performance side by side with something that is 'supposed' to be better.
