Blue Nile does not sell “公平” または “poor” diamond cuts
While 35% of the diamond market is made up of fair or poor cuts, Blue Nile does not offer them. Diamonds with low cut grades often appear glassy or dull, or just plain small, and they don’t live up to our standards of great quality at a great value.
