Heart Diamond Rings

A heart cut is a single heart outline with a cleft at the top, produced by a modified brilliant pattern. Because the shape depends entirely on proportions, well-executed hearts are rarer than they look.

How a heart is graded

Lab-grown heart diamonds are graded on the same 4C scale as every other diamond — carat, color, clarity, and cut. Cut grading for fancy shapes assesses face-up appearance, facet arrangement, and light performance. Heart stones with good proportions are scarce relative to demand, which affects both price and availability.

Price and what to expect

Heart cuts are less abundant and priced above rounds. Symbolism carries most of the appeal, and it is genuine rather than a marketing device.

Where to spend and where to save

Spend on clarity and polish. The heart's shape depends on precise symmetry, and a heart with a visible cleft or lopsided lobes is immediately obvious. Symmetry is the first thing to inspect.

For any shape, checking the grading report is non-negotiable. Read how to verify a diamond certificate and confirm the report number with the laboratory directly before you commit.

Settings that suit a heart

Heart diamonds have an elongated outline, so the setting shape matters as much as the metal. Solitaire and bezel settings protect the points of the stone most effectively, which is a practical consideration for any shape with vulnerable corners. Halo and pavé settings add light but can visually shorten an elongated outline — a common problem people bring back to us after seeing a ring in person.

Frequently asked questions

How do I know if a heart is well-proportioned?

Look at the cleft. A well-made heart has a distinct, defined cleft and balanced lobes with no pinched or lopsided area. We can show you examples side by side, and we would encourage you to view the actual stone.
