About Blue Nile
Blue Nile has sold jewelry online since 1999: loose natural and lab-grown diamonds, engagement and wedding rings, fine jewelry and the James Allen collection.
Loose diamonds carry no promotional discounts, so codes and banner sales only touch settings and jewelry, while the stones rely on the price match.
Blue Nile calls itself the original online jeweler, and it says every piece is assembled in its US studios using responsibly sourced diamonds. Buyers can build their own engagement ring, earrings or pendant by starting from a diamond, a setting or a gemstone, and loose stones come with grading reports and 360° imagery. Collections include SIX by Royal Asscher, The Clear Cut, Modern Pavé, Ellipse and Something Blue.
The wider catalog covers tennis bracelets and necklaces, eternity and anniversary rings, pearl pieces, birthstone jewelry for each month, and men's wedding bands in tungsten, titanium, tantalum, platinum and gold. Shoppers who want to see stones in person can visit a showroom or book a virtual appointment.

Blue Nile coupon searches peak in December, about 1.9× a typical month, and dip lowest in June.
Does Blue Nile offer free shipping?
Yes. Every domestic order ships free and insured; orders over $500 go overnight, and smaller ones go two-day.
What is Blue Nile's return policy?
You have 30 days from the ship date for a refund or exchange of unworn pieces with grading reports.
Does Blue Nile price match?
The Diamond Price Match Guarantee covers loose diamonds advertised for less by a qualified competitor.
What payment methods does Blue Nile accept?
Cards, PayPal up to $50,000, Affirm, Splitit, bank wire and the Blue Nile credit card are all accepted.

How to use a Blue Nile coupon
- Start by splitting your cart in two.
- A loose diamond is priced at sourcing cost and takes no promotional discount, so any code or sale lands only on the setting or other jewelry.
- For the stone itself, find a comparable diamond listed lower by a qualified competitor and ask Blue Nile to match it.
- Still deciding?
- Contact Blue Nile within 72 hours to hold a chosen diamond's price.
- Banner offers like the Fall Edit, up to 30% off, cover select jewelry rather than loose stones.
If your Blue Nile code doesn't work
- Exclusions: Loose diamonds carry no promotional discounts; they are priced at sourcing cost and covered by the price match instead.
- End date: "$10 Off $50 Orders of Regular-Priced Jewelry" ends Nov 17, 2026.

Blue Nile questions, answered
Do Blue Nile coupons work on loose diamonds?
Loose diamonds carry no promotional discounts because they're priced at sourcing cost. The Diamond Price Match Guarantee is the route to a lower price on a stone.
Is there a discount for paying Blue Nile by wire?
Wire transfers of $1,000 or more get a 1.5% discount. Bank wire sits alongside cards, PayPal, Affirm and Splitit as a payment option.
Does Blue Nile resize rings for free?
Eligible rings get one free resize, up or down two sizes, within 6 months of purchase. A resized ring can't then be returned.
Can a diamond's price be held at Blue Nile?
Contact Blue Nile within 72 hours and it will lock the price of a chosen diamond while you decide.
