HEARTS & ARROWS
When viewed from the top (crown), an ideally cut diamond should reveal eight symmetrical arrows. On the other hand, when the diamond was viewed from the bottom (pavilion), it should reveal eight symmetrical hearts.
Due to the extreme level of cutting precision required for symmetrical patterning, Hearts and Arrows diamonds are sometimes called “super ideals”. Fast forward to modern-day, the term “super ideal” is used to define a diamond with superior light performance, material quality, and precise optical symmetry.
So does an “Ideal” Cut Rating equate to Hearts And Arrows? The answer is NO. Not all diamonds with an ideal cut rating (AGS) or excellent cut rating (GIA) will automatically qualify it as a hearts and arrows diamond. Technically speaking, the formation of a precise H&A; patterning is due to extreme care that is taken when polishing each facet to exact angles and proportions. This level of precision goes way beyond the criteria needed to achieve an “excellent” symmetry rating.
Also, taking a great picture or viewing the hearts and arrows patterning isn’t a straightforward process. It does require some practice especially if you had no prior experience. Any slight tilt of the diamond or your eye (even by a minute 0.5 degrees) would cause the patterning to be slightly skewed. Do bear this in mind when you are physically examining diamonds in stores.
