Since its founding in 1999, Blue Nile has grown to become the largest online retailer of certified diamonds. We offer thousands of certified diamonds which can be used to create diamond engagement rings, earrings, and pendants. Every loose diamond sold by Blue Nile has been analysed and graded by either the Gemological Institute of America (GIA) or the American Gem Society Laboratories (AGSL).

Because we provide customers with the best value and service, you will convert more traffic and drive higher revenue. Commissions are a tiered percentage of sales. We also give credit for phone sales and online orders based on a 30-day cookie.

At Blue Nile, our philosophy is simple: Offer high-quality diamonds and fine jewelry at outstanding prices. When you visit our Web site, you'll find extraordinary jewelry, useful guidance, and easy-to-understand jewelry education to help you find the jewelry that's perfect for your occasion. Blue Nile diamond and jewelry consultants have years of experience, and they don't work on commission.

Every order is shipped free and insured to its destination. Our 30-day returns policy offers customers a month to consider their purchase. Orders without custom engraving in its original condition can be returned any time within 30-day returns for a full refund.
