The Blue Nile Story Blue Nile was founded in 1999 with the idea that the diamond and engagement ring business was ready for innovation. We revolutionized the industry with a disruptive online business model, making it possible to shop for extraordinary, high-quality diamonds at a great value. And we didn’t stop there. We also firmly believed that our customers deserved more choices, straightforward information and legendary service. We felt strongly about building a team of passionate, non-commissioned diamond and jewelry experts who put the customer first. As the leader in handcrafted engagement rings and beautiful fine jewelry, we’re constantly innovating and looking for new ways to help you discover and design the perfect pieces for every occasion. We strive to be your jeweler for life.
