LAB GROWN HEART SHAPED DIAMONDS

A heart is a pear with a cleft cut into the round end. It's the hardest common shape to cut well, because the two lobes have to match each other and the cleft has to be sharp, and it needs size before it reads as a heart at all. Choose from 3 pieces, pendant, ring and bridal set, every one of them lab grown, in 14K or 18K white, yellow, or rose gold, or platinum, with prices ranging as low as $1,075.99

THE DETAILS

Buying a Lab Grown Heart Shape

A short shelf, and a shape that rewards size more than any other. Here is what to know before you pick one.

Because that's what we list ready to order in heart shape, and we won't pad a page with the same design at three more weights. A heart halo, a three stone, studs or a heavier center is made to order. The 3D design is free and takes no deposit.

Around three quarters of a carat before the shape reads clearly at arm's length. Below that it starts to look like a rounded stone with a notch in it, and the cleft is the first thing to disappear.

Symmetry, mostly. The two lobes should mirror each other, the cleft should be sharp and centered, and the point at the bottom should line up with it. It's the shape where a poor cut is easiest to see without knowing anything about diamonds.

Yes, and here the price difference matters more than usual. Cutting a heart throws away a great deal of the rough crystal, so a mined heart at the size this shape needs gets expensive fast. A lab grown heart of the same specification costs well under that, which is how you buy the size the shape actually wants.

Often, yes. A pendant hangs flat and gets looked at straight on, which is exactly how a heart wants to be seen, and there's no knuckle for the point to catch on. On a ring the point sits under a V prong and the shape still reads, it just competes with the hand.

About Our Lab Grown Heart Shaped Jewelry

A heart shaped diamond is unmistakably a choice. Nobody buys one by accident and nobody misses it across a room. It's also the most demanding shape to cut, which is why there are fewer of them than of anything else and why a good one is worth waiting for.

All 3 pieces here are made to order in our own US factory, in 14K or 18K white, yellow or rose gold, or in platinum, around the center weight you choose.

The stones run every one of them lab grown, and prices range as low as $1,075.99. It's a short shelf, and that's the real number rather than a modest one.

Anything else in heart shape is made to order and drawn in 3D before a stone is set, at no charge and with no deposit. Every piece ships free inside the US, carries a Lifetime Limited Labor Warranty on the setting work, and comes back within 30 days of the ship date if it isn't right.
