Don't automatically pay extra for the highest clarity. For most jewelry, cut is the most important of the 4Cs for appearance. I'd also insist on an independent grading report (commonly IGI or GCAL) and compare the actual stone's proportions, video, and price rather than just searching by carat/color/clarity.
If you tell me what you're buying (engagement ring, loose diamond, earrings, etc.), your budget, and desired carat size, I can narrow it down to the best places and specific diamonds for you.
