Blue Nile Signature Hearts And Arrows
Signature Cushion Standards:
Hearts and Arrows:
The patented Blue Nile Signature cushion-cut diamond displays unparalleled light performance for this shape. These modern cushion-cut diamonds were designed and created exclusively for Blue Nile. They feature a one of a kind facet structure that was designed specifically to display the level of brilliance, fire, and scintillation normally found only in round brilliant-cut diamonds.
Each Blue Nile Signature cushion-cut diamond is cut to exacting proportions. Every dimension and angle must fall within a very narrow range for the diamond to earn its Signature report. Additionally, the length-to-width ratio is limited to 1.05 or less, ensuring a perfectly square cushion-shaped outline. The extremely tight tolerances ensure that every Blue Nile Signature cushion-cut diamond displays the same level of unparalleled light performance.
Hearts and Arrows
The term "hearts and arrows" is used to describe the visual effect achieved when a diamond is cut with perfect symmetry and angles, and is indicative of exceptional brilliance. The Blue Nile Signature cushion cut diamond features a unique set of proportions that display the hearts and arrows pattern typically found only in round brilliant-cut diamonds. When viewed under special lighting filters, the perfectly aligned facets of the Blue Nile Signature cushion-cut diamond reveal the instantly recognizable hearts and arrows pattern: eight perfectly symmetrical hearts can be seen when viewed from the bottom, and eight completely uniform arrows can be seen when viewed from the top.
All Blue Nile Signature Collection diamonds are accompanied by a Certificate of Authenticity issued by the Gem Certification & Assurance Lab (GCAL) in addition to being graded by the Gemological Institute of America (GIA) or American Gem Society Laboratories (AGSL). This provides you a second authoritative analysis of your diamond and verifies that your diamond meets all the specific quality requirements of the Blue Nile Signature Collection, including an optical light performance profile. All Signature diamonds are inscribed with the Blue Nile logo and the unique certificate number on the girdle, visible with magnification.
