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 jewelers then precisely shape the stones into elegant emerald cuts, sparkling princess cuts, and other radiant, symmetrical designs. These diamonds are certified by independent diamond-grading labs and set into jewelry 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.
