Basics and Analysis
A complex cut, the beauty of a heart diamond is more in its balance and proportions than optical qualities such as brightness or fire.

Among the various diamond shapes the classic heart diamonds is a brilliant cut with curved lobes that stem outward from a centered cleft, sloping down to form a sharp point. The shape dates back to the 16th century, when history records a heart diamond coming as a gift to Queen Elizabeth from Mary Queen of Scots. They are typically shallow and are often cut from flattened, triangular rough called macles, facilitating the low profile of the heart diamond ring.
The Fancy, Inconvenient Truth
The heart diamond is often cut for heavier weight, at the expense of beauty. This is because many grading laboratories, including GIA, do not assess the optical performance of the heart diamond or other fancy shapes. With no standards enforced, manufacturers tend to plan for the highest yield possible.
The AGS and GCAL assess and grade the optical performance of certain fancy shapes. If you’re seeking cut quality affirmation, fancy shapes with performance deficits will not earn the highest marks from those top-tier laboratories.
Bow Tie Caution
A bow tie is a dark area across the center width of the heart diamond resulting from a combination of cutting angles. While well-proportioned heart diamonds should have a minimal bow tie effect be sure to check for this deficit. Viewing a diamond spin-video or images under a variety of lighting conditions will help you identify this.
The oval diamond, marquise diamond, heart diamond, and pear shaped diamond all tend to have bow ties of varying degrees, such as the moderate bow tie seen in this oval cut diamond.
Length to Width Ratio:
A ratio between 1.0 and 1.1 is most desirable for the heart diamond shape. Going above 1.1 will make the heart diamond appear stretched.
A well-cut Heart Shaped Diamond should be symmetrical, so it appears balanced and full. A defined cleft and distinct, pointed lobe will give a cleaner silhouette. In a heart diamond ring the point is most frequently set pointing toward the wearer’s heart.
Color can be more visible in the heart diamond, especially in the lobe areas. This is because the shallow profile tends to emphasize color in the center. For this reason the heart diamond shape is frequently chosen for fancy color diamonds.
The heart diamond shape is most appealing and effective in higher carat weights.
