Experts in the diamond industry disagree on which diamonds should receive the ‘Hearts and Arrows’ label. This is because there is no industry standard, therefore one person or company can label a diamond as ‘Hearts and Arrows’, while another may not agree. In the diamond industry, the term ‘super ideal’ is a common term that is used to describe diamonds that have perfect optical symmetry. Most diamonds with an overall cut graded by GIA as ‘3 x Excellent’ (with Excellent cut, symmetry and polish) or American Gem Society as ‘0’ (or ‘Ideal’) will have some sort of hearts and arrows pattern when seen through a H&A viewer, but the pattern may not be perfect. Most experts in the diamond industry believe the Hearts and Arrows pattern should be graded, and only those with the highest grade should be called Hearts and Arrows. Those people also believe that the presence of the Hearts and Arrows pattern alone is not enough to be considered a Hearts and Arrows diamond; the pattern must be perfect to fit within certain guidelines.
