There’s been much buzz in recent years about conflict diamonds—diamonds that are illegally sold or traded to fund violence in war-torn areas. Blue Nile maintains a zero-tolerance policy toward conflict diamonds, and works only with established, reputable suppliers that track diamonds from mine to market. Choose a Blue Nile coupon code to save on a sparkling stone that’s both visually stunning and socially responsible.

Snap up the best savings with Blue Nile

Experts often say that a diamond’s cut is its most important characteristic, since the angles of a stone’s surfaces determine how it will sparkle. For that reason, Blue Nile takes extra care to source diamonds with superior cuts. The process starts with rough diamonds found in nature, which are analyzed by master gemologists to determine which cut and proportions will yield the most brilliant effects. Experienced jewellers then precisely shape the stones into elegant emerald cuts, sparkling princess cuts, and other radiant, symmetrical designs.

The best of Blue Nile

These diamonds are certified by independent diamond-grading labs and set into jewellery made from gold, platinum, and other precious metals. Shoppers can browse Blue Nile’s website until they fall in love with a particular ring, or bring their own vision to life with the Build Your Own Ring function. Use a Blue Nile coupon to save and add some stunning new jewellery to your collection.
