How Blue Nile pricing actually works
Diamond pricing here moves on cut, colour, clarity and carat rather than on codes — the difference between two stones of the same carat is far larger than any discount. Settings and stones are priced separately.
The stone specification moves the price far more than any code. The promo code field is at checkout with the order summary. Loose stones and settings are priced separately, and codes frequently apply to one but not the other.
- 1
Compare stones on specification, not price
Cut quality especially changes both appearance and price, and two stones of the same carat can differ enormously.
- 2
Check whether the code covers the stone or the setting
Loose diamonds and settings are priced separately, and codes commonly apply to only one.
- 3
Drop just below a round carat weight
Prices step up sharply at round carat figures, and a stone just under one saves more than a code.
- 4
Check the certification
An independent grading report is what makes the specification verifiable, and an ungraded stone is not comparable.
