Blue Nile Sells Real Diamonds You can rest assured that all the diamonds we sell are real, and we offer the paperwork to confirm this. If you're purchasing diamond jewelry or loose diamonds from our online jewelry store or local jewelry showrooms, you can rest assured that you are purchasing genuine diamonds.

Blue Nile diamonds are absolutely legit. But because they cost less than diamonds at brick-and-mortar retailers, it's understandable how someone shopping for a diamond or jewelry piece might be skeptical. The price difference is all in the business model.

Blue Nile is a marketplace that thrives on having a large listing of inventory on their website. By design, they want to have diamonds that are high quality and others that are at a lower quality to be at a lower price point.

Can you negotiate price with Blue Nile? We offer the finest GIA-graded, conflict-free diamonds and resposibly-mined precious metals, and this is reflected in our prices. We do not offer price negotiation, however, we are so certain that our diamonds offer the best value that we offer a Diamond Price Match Guarantee.
