Coupons & Promo Types
All the ways to save at Blue Nile. Each promo type can often be combined — see the Stacking Tips section.
Everyday Diamond Savings vs. Traditional Retail
Blue Nile's direct-to-consumer model prices certified diamonds and engagement rings 20–40% below equivalent quality at traditional retail jewelers (Kay, Zales, Tiffany, local jewelers). This is not a promotional discount — it is the structural everyday pricing advantage of eliminating traditional retail markup. Every day is a "sale" relative to traditional jewelry retail.
OngoingBuild-Your-Own Engagement Ring
Blue Nile's build-your-own tool lets buyers select a diamond (from 100,000+ certified stones) and a setting separately, enabling quality-per-dollar optimization unavailable in traditional jewelry stores. Separating the diamond from the setting selection allows buyers to allocate their budget toward the specific quality factors (cut, carat) that matter most to them.
OngoingHoliday and Seasonal Promotions
Blue Nile runs promotional events on fashion jewelry, wedding bands, gemstone pieces, and non-diamond jewelry during Valentine's Day, Mother's Day, the holidays, and other gifting occasions. These events offer 10–25% off select categories. Certified diamond and engagement ring pricing is consistently competitive year-round without promotional timing.
Seasonal0% APR Financing
Blue Nile offers 0% APR financing on jewelry purchases through third-party financing partners. Promotional no-interest financing periods allow buyers to spread the cost of a significant engagement ring or jewelry purchase over monthly installments without added interest — making Blue Nile's already-lower pricing even more accessible.
OngoingBlue Nile Diamonds on Demand
Blue Nile sources diamonds from multiple vetted suppliers, enabling a broader selection and fresher inventory than traditional jewelry stores that purchase and hold finished inventory. This sourcing model also means Blue Nile can offer diamonds at different price points when specific combinations of cut, clarity, carat, and color are identified — creating opportunities for buyers who are flexible on specifications.
OngoingEmail Subscriber Promotions
Blue Nile email subscribers receive promotional codes on fashion jewelry, bands, and select non-diamond pieces during holiday gifting seasons and sale events. Email is the primary channel for limited-time promotional codes on Blue Nile's non-diamond jewelry categories.

Stacking Tips
Combine multiple discount types in a single transaction. These are the most effective stacking combinations at Blue Nile.
Build-Your-Own + Cut Quality Optimization
Blue Nile's build-your-own tool enables a quality-optimization approach unavailable at traditional jewelers: choose an Excellent cut grade first (cut is the most impactful quality factor) and then optimize carat weight and clarity within budget. A 0.95-carat Excellent cut diamond often looks identical to a 1.0-carat stone while costing 10–15% less — a strategy that maximizes visual impact per dollar.
0% Financing + Everyday Savings vs. Retail
Blue Nile's structural 20–40% price advantage versus traditional jewelry retail combined with 0% APR financing creates the optimal engagement ring purchase scenario: pay a lower total price spread over installments with no interest added. For a $5,000 engagement ring, this can mean $1,000–$2,000 in savings versus a traditional jeweler, paid over 12–24 months with no interest.
Holiday Promotion + Fashion Jewelry Gifting
Blue Nile's holiday promotions (Valentine's Day, Mother's Day, holiday season) offer 10–25% off fashion jewelry, gemstone pieces, and wedding bands. These promotions don't apply to certified diamonds (everyday pricing is already the best value), but they create meaningful savings on gifting jewelry — a great opportunity for anniversary, birthday, or holiday gifts.
Diamond Comparison + Price Flexibility
Diamond pricing jumps at common carat thresholds (0.50, 0.75, 1.0, 1.5, 2.0 carats). Blue Nile's 100,000+ certified diamond inventory makes it easy to find high-quality stones just below carat thresholds — a 0.97-carat stone looks identical to a 1.0-carat stone but costs 10–20% less. This threshold optimization is the most reliable per-carat savings strategy in diamond purchasing.
Price Match Policy
Blue Nile's price match guarantee lets you claim a lower price from qualifying competitors — both at the time of purchase and up to 14 days after. Knowing the rules can save you from overpaying on big-ticket items.
No Formal Competitor Price Match
Blue Nile does not offer a formal competitor price match policy. However, Blue Nile's everyday pricing is structured to be 20–40% below traditional jewelry retail — making a price match request against traditional retailers unnecessary for most buyers.
30-Day Price Adjustment
Blue Nile offers a price adjustment within 30 days if an item purchased at Blue Nile drops in price. Contact Blue Nile customer service with your order number for the adjustment.
