Cut is considered the most important characteristic of a diamond, because it has the biggest effect on brilliance. This is why we created the Blue Nile Signature Diamond Collection – for those who want the finest diamond cut available.
Cut from the Finest Rough
To ensure the highest quality, we start with the finest uncut diamond rough found in nature. Because of its natural shape and crystalline structure, the diamond rough is first cut in two. Then each piece is meticulously analyzed by our master diamond gemologists, who mark it for facets with proportions that will produce the most brilliance.
Brilliance is Key
The dimensions of the Blue Nile Signature diamond are very specific, leaving no room for error. If a diamond is cut even slightly out of proportion, it may yield more carat weight but it will not be as brilliant. In fact, to create a diamond with this much brilliance, as much as 74% of the diamond rough must be cut away. The Blue Nile Signature round diamond comes with an additional certification from the Gem Certification & Assurance Lab that shows the exceptional amount of brilliance emitted from these diamonds.
Perfect Proportions
Proportions affect how light travels within the diamond. Diamonds that are cut too shallow and wide, or too deep and narrow lose light out the sides or bottom, causing the diamond to lose brilliance. Blue Nile Signature Diamonds are cut to perfect proportions, allowing the diamond to reflect the maximum amount of light a diamond can produce.
Exceptional Symmetry
The alignment of a diamond's facets, or symmetry, also has a strong effect on diamond brilliance. Each facet is like a mirror. When the facets are symmetrically aligned, all of that reflected light is focused directly at your eye. In the illustration to the left, the diamond on the left has poor symmetry and the facets do not align. As a result, light is misdirected within the diamond and brilliance is lost. The diamond on the right is a Blue Nile Signature Diamond, its facets are symmetrically aligned and cut to standards that ensure its brilliance is emitted evenly.
Double Certification
All Blue Nile Signature Collection diamonds are certified by GCAL in addition to being graded by the GIA or AGSL. This provides you a second authoritative analysis of your diamond. GCAL also verifies that your diamond meets all the specific quality requirements of the Blue Nile Signature Collection.
With perfect symmetry and perfect proportions, Blue Nile Signature Diamonds are cut to gather and reflect light, for maximum brilliance. Come see the finest of all ideal-cut diamonds in the Blue Nile Signature Collection. Choose from round, princess-cut,emerald-cut or Asscher-cut diamond shapes
