THE DETAILS

Buying a Heart Cut Diamond

Answers first, from the bench that sets the stones. Every piece here carries a Lifetime Limited Labor Warranty and a 30-day return window. US shipping is free, and Affirm sits at checkout if you'd rather spread the cost. We make your piece in 5 to 7 business days. US shipping is 1 to 3 business days, depending on the option you pick. If something isn't answered below, contact us and we'll answer it.

On a grading report it's a heart modified brilliant. At the bench we just say heart cut or heart shape. The modified part matters: the facet pattern is the round brilliant's, reworked to fill the heart outline, so a good one sparkles the way a round does. Every diamond on this page is natural, mined rather than grown.

Usually not against a round of the same weight. What you're really paying for in a heart is the cutting: the two lobes have to mirror each other, and a lopsided heart shows from arm's length in a way a slightly imperfect round never does. Here, prices ranging as low as $223.99 run to $7,103.99, with the middle of the shelf at $2,997.99, because you're buying straight from the factory.

There isn't one number: color, clarity and cut quality move the price more than the carat mark does. This shelf has prices ranging as low as $223.99 and tops out at $7,103.99. Open the piece you like and the live price is on the page. If you want help choosing between two stones, contact us.

No more than any other diamond, as long as the point is covered. The point at the bottom and the cleft between the lobes are where the stone is thinnest, and the point is where a hard knock does damage. A prong sitting over the point takes that risk off the table, and it's the standard way a heart gets set. Check the point on any heart you buy, here or anywhere.

Yes, and it's the most direct one there is. Nobody has to be told what it means. Face up, look for two lobes that match and a clearly defined cleft, because symmetry is what makes a heart read as a heart. The smaller the stone, the harder the outline is to see, so the shape rewards a slightly larger center stone.

About Our Heart Cut Diamond Jewelry

A heart cut says exactly what it means, and no other diamond shape does. It's a modified brilliant, so the faceting sparkles like a round while the outline does the talking: two lobes, a cleft between them, a point at the bottom. We've made our own jewelry in our own US factory since 2001, and the price you see is the factory's, with no store standing in between.

All 168 diamonds here are natural, every one of them heart cut, and every one a LOOSE stone sold on its own. The loose stones come EGL certified unless a listing says otherwise. Pick the carat and grade that fit your budget, and we set it in the piece you choose: an engagement ring, a pendant, or earrings, made to order in our own US factory.

The least expensive piece here is $223.99, the most expensive is $7,103.99, and the middle of the shelf sits at $2,997.99. The setting you pair it with is made to order in 14K or 18K white, yellow or rose gold, or in platinum. If it's a ring you're after and you want every shape side by side, see our diamond engagement rings. For a heart worn at the neckline, our diamond pendants and necklaces page carries the full range. And if you're stuck between two pieces, contact us and we'll help you decide.
