We seek to exceed industry standards in every detail, not to mention our secure delivery,
30-day returns and lifetime guarantees. How do we see our standards through? Our fulfillment center has a state‐of‐the‐art laboratory that supports our quality review process. This means that:
Our diamond and gemstone products are inspected by a GIA-certified gemologist or inspector. They use a microscope, digital calipers, a GIA-certified diamond master color comparison set, x-ray spectrometer and other advanced technological equipment to judge the authenticity, quality, stone security and potential structural weaknesses of every stone we sell.
Our metal jewelry is inspected by trained quality inspectors using an unaided eye at twelve inches, digital calipers, x-ray spectrometer and a universally calibrated ring mandrel. If you receive jewelry from us, it has been inspected with these methods under our roof.
Blue Nile engagement rings and fine jewelry are crafted for a lifetime of enjoyment. Every piece is designed for beauty and comfort and consistently tested to ensure lasting quality and value.
