If you want to be in the know about diamonds.
I could not imagine going to a better store for help. You set up a private time to go in and talk/look over diamonds. They'll tell you about everything you need to know, clarity, cut, etc. to make sure you get the best diamonds you can afford. I felt as though it was a fmaily member helping me make a purchase, rather than someone going for a sale. No pressure to buy up, only that you're happy. He even talked price range when I set up my appointment so as not to have anything I couldn't afford sitting out.
