HCA gives it a "4.1 - Good - Only if price is your main criterion." I''d pass on it. If price is a big concern, consider dropping the clarity to SI1 and maybe going a tiny bit smaller on size.
Also, Blue Nile doesn''t have an upgrade policy, so if that''s important to you (many people don''t consider it at first but then regret not getting one), look elsewhere. Whiteflash, Good Old Gold, and James Allen are good places to start.
Plug in the specs of the stone you are considering. You will want to read about the HCA tool. It is not a selection tool, but rather an exclusion tool. Meaning if it falls in the preferred areas, it''s likely that the cut is going to net you a beautiful diamond to own.
