Heart lab-grown diamonds are the most symbolic of shapes — a brilliant cut where even lobes, a sharp cleft, and balanced wings define a truly beautiful stone.
No diamond shape carries more meaning than the heart. It is the unmistakable symbol of love, which makes it a romantic choice for engagement rings, anniversary pendants, and milestone gifts where the message matters as much as the stone. Built on a brilliant-cut foundation, a well-made heart sparkles with the same fire as a round or pear while wearing its sentiment on its sleeve.
Because the heart is so distinctive, it rewards careful selection more than almost any other shape. A beautifully cut heart is balanced, crisp, and instantly recognizable; a poorly cut one looks lopsided or vague. That is why buying a heart is really an exercise in judging symmetry — and why a clear video matters so much. Get the proportions right and you have one of the most personal and charming stones in the case.
Symmetry comes first. The two lobes should match in size and shape, the cleft between them should be sharp and centered, the wings should curve down evenly, and the point should line up directly under the cleft. Fold the outline in half in your mind — both sides should mirror perfectly. This balance, more than any grade, is what makes a heart beautiful.
Go at least half a carat. A heart needs room to read as a heart. At 0.50 carat and above, the lobes and cleft are clearly visible; much smaller and the shape can look like a round or pear once it is set. If the heart silhouette is the point, give it the size to show.
Use the brilliant faceting to save. Like other brilliant cuts, the heart hides small inclusions and faint color well, so G or H color and an eye-clean SI usually look white and clean. Faint color can gather near the point, so check there on the video.
Plan to protect the point. The bottom tip is fragile and should be held by a V-prong or bezel; many heart settings use a five-prong layout to keep the stone centered and the point safe. With that protection, a heart wears reliably day to day.
Even lobes, a sharp centered cleft, and a point in line with it. Fold the outline in half in your mind — it should mirror.
A heart needs size to read clearly. Below half a carat the shape can look like a round or pear once set.
A V-prong or five-prong setting shields the fragile tip and keeps the stone centered for everyday wear.

Symmetry is everything in a heart cut. The two rounded lobes should be the same size and shape, the cleft between them should be sharp and centered, the wings that sweep down to the point should curve evenly, and the point itself should sit directly in line with the cleft. If any of those elements is off, the heart looks lopsided. Because grading reports do not fully capture how balanced a heart looks, you should always judge symmetry yourself on the video.
A heart reads best at about half a carat and up. Below that, the lobes and cleft that define the shape become hard to see, and a small heart can be mistaken for a round or pear at a glance, especially once it is set. If you want the heart shape to be clearly recognizable, choosing 0.50 carat or larger gives the outline room to show itself.
Fairly well. The heart is a brilliant cut, so its faceting scatters light and helps mask small inclusions and faint body color, much like a round or pear. You can usually choose a near-colorless grade such as G or H and an eye-clean SI and still get a bright, white-looking stone. As with a pear, faint color can gather near the point, so glance there on the video.
The point at the bottom of a heart is its most fragile spot and should be held securely, typically with a V-shaped prong that wraps the tip, or with a bezel. Many heart settings use a five-prong arrangement, with prongs at the point, the two lobes, and the shoulders, to keep the stone centered and the tip safe. With proper protection, a heart is suitable for everyday wear.
Most people find a length-to-width ratio close to 1.00 the most pleasing, meaning the heart is about as tall as it is wide, which gives a balanced, classic silhouette. Slightly wider hearts below 1.00 look fuller, while taller hearts above 1.00 look more elongated. It is a matter of taste, so compare a few outlines, but a near-1.00 ratio is the safe, traditional choice.
