Hearts & Arrows

Hearts & Arrows

Hearts and Arrows can best be described as diamonds that must have Excellent make proportions coupled with perfect symmetry. Excellent cut diamonds were known to show the "Cupid Effect" which is a visual pattern of 8 hearts while looking down through the pavilion and 8 arrows when viewing the diamond from the table up position. A special Hearts and Arrows magnifying viewer (scope) is used to show this effect.

Not all diamonds cut to Excellent proportions will show this effect. The most important difference between diamonds cut to Excellent proportions and Hearts and Arrows is Symmetry. The Hearts and Arrows pattern is only possible when exceptional symmetry exists.

The pictured images are produced when viewing a diamond with perfect symmetry when seen through a special Hearts and Arrows viewer. The left image is of the table- down position creating the 8 hearts. The right image is viewed table up and shows the 8 arrows.
