What does the term "hearts and arrows" refer to in diamonds?

The term "hearts and arrows" refers specifically to a visual phenomenon that signifies perfect symmetry in certain diamond cuts, primarily in round brilliant diamonds. When viewed under a special scope, a well-cut diamond will display a pattern of eight arrows on the table and eight hearts on the pavilion. This precise alignment and symmetry lead to optimal light performance, contributing to the diamond’s brilliance and sparkle.

Diamonds that exhibit this characteristic are often sought after by collectors and those in the jewelry market because they represent high-quality craftsmanship. The hearts and arrows pattern serves as a hallmark for symmetry, making it a significant factor for buyers looking for exceptional diamonds. Understanding this concept is essential when assessing diamond quality and value in the market.
