Heart Cut Lab Grown Diamond Engagement Rings

What the Center Stone Adds to Heart Lab Grown Diamond Engagement Rings

The 530 or more heart lab grown diamond engagement ring designs in the grid are all shown in 14K white gold. The diamond itself is the larger share of what you pay. You pick that center from 49,909 lab hearts in stock today, and 42,604 of them have a 360 HD video for checking the lobes and the point. After today's savings the cheapest lab heart is $130. In the 0.90 to 1.10 carat rows, the size the images use, the lowest is $410 and the median $597. Priced as finished rings with a 1 carat lab heart in place, the Bellora hidden halo comes to $1,400 and the Marie hidden halo to $805. We pulled these figures from stock on October 17, 2026 and update them regularly.

Cutting a heart well is harder than cutting any other outline, since the two lobes, the cleft between them and the point all have to match. Below about half a carat the outline no longer reads clearly. A lab stone takes the cost out of going larger, so most of the heart lab grown engagement ring designs here carry a one to two carat center, picked for symmetry on the video.

What a Lab Grown Heart Costs at Each Carat

All 49,909 lab hearts in our inventory are sorted into carat rows in the table below, and the rows total that same count. The 0.90 to 1.10 carat row is the largest, with 13,997 stones, and the median between 0.90 and 1.10 carats is $597. It rises to $1,596 for 1.90 to 2.10 carats and reaches $2,954 at 2.90 to 3.10. Choose any design on the grid and the price shown is the stone plus the mounting. Swapping in a different stone moves the total by the difference in stone price. Where a row matches one of our ring pages, the row is linked, and that page shows the same designs at that weight.

Choosing Color and Clarity in a Lab Heart

Between 0.90 and 1.10 carats, 99 percent of the lab hearts on our color ladder grade D to F. That tells you color is not where a lab grown heart engagement ring saves money or costs more: with clarity fixed at VS2 or better, a D starts at $495 and a G at $435. The clarity ladder tells the same story from the other side. With color fixed at D to F, a VS1 lab heart starts at $440, and a VVS2 starts at $435. For a heart center that leaves D to F at VS1 or better as the practical choice. Whatever you would have paid for a higher grade can go into carat weight and into the mounting.

Lab grown hearts between 0.90 and 1.10 ct: lowest price at each color with clarity VS2 or better (13,937 stones), then at each clarity with color D to F (13,789 stones)

The Same Ring with a Natural Heart

Put a natural heart in the same mounting and the price of the ring changes a good deal. For a G color VS1 heart of one carat, the lab grown price starts at $490 and the natural price at $1,245, and over the whole one carat row the medians are $597 against $1,885. What the natural stone gives you is scarcity and, for 22,789 of the 25,353 natural hearts we stock, a GIA report. The lab stone gives you more weight and higher grades for the same outlay. The heart natural diamond engagement rings page runs the same designs down the natural route, and both origins sit together in the heart diamonds grid.

How a Heart Should Be Set

On the bench, a heart gets a V shaped prong over the point and a single prong on each lobe, three prongs in total, or a bezel that traces the outline. Whichever you choose, keep the cleft open, because that notch is what makes the shape read. A solitaire shows the outline more plainly than any other mounting. Since a lab heart costs so little at one and a half to two carats, a heart lab grown engagement ring that size reads from across a room. In a pendant the point hangs down, while on the hand it can go either direction.

At one carat a lab heart runs about 6.5 by 6.5 mm across, which is roughly the stone the heart lab grown diamond engagement ring designs here are shown with, in 14K white gold. Yellow gold, rose gold and platinum versions of each design exist as well, and the stone you select is shown mounted in whichever metal you pick. Our AI price score sets the stone against comparable lab hearts in stock and flags any that cost more than their peers. The quality score weighs cut, color and clarity together and reports a figure out of 18. Gemologists on our staff are paid no commission, and by chat or phone they'll put two or three heart finalists side by side on video with you.

The stone counts and prices above come from every lab grown heart diamond Rare Carat had in inventory on October 17, 2026. They use the same filters as the diamond grids: graded by GIA, IGI or GCAL; video or no video; color D to K; clarity FL to SI2; cut Good or better. That gives 49,909 lab grown hearts, of which 42,604 have 360 HD video, plus 25,353 natural hearts used for the comparison. Each price is the amount you pay today with savings taken off, and the regular price appears struck through next to it on the stone. A starting price means the cheapest stone in that row, whatever its grade. A ring price means the finished ring exactly as this page displayed it, in 14K white gold with the center stone stated, on October 17, 2026, and the design count is whatever the page reports. For the color and clarity ladders we held carat to 0.90 to 1.10 so that grade alone moves the price.
