Hearts and Arrows

The term Hearts and Arrows is used to describe the visual effect achieved in a round diamond with perfect symmetry and angles. The Hearts and Arrows effect is exhibited in all of our round Blue Nile Signature Collection diamonds. When viewed under special magnification, the perfectly aligned facets of the Blue Nile Signature diamonds reveal the Hearts and Arrows pattern. From the bottom, eight perfectly symmetrical hearts can be seen and, when viewed from the top, eight completely uniform arrows.
