Heart shaped lab grown diamonds: what to look for
Look for even lobes, a clear cleft and a straight, centered point; a ratio of 0.90 to 1.10 gives a balanced heart. Our heart shaped diamond guide covers the shape in more detail.
Heart shaped diamond sizes and prices
Carat measures weight, not size. These are the typical measurements and lowest prices of the heart shaped lab grown diamonds in our stock today, by carat size:
| Carat | Typical size | Available | From |
|---|---|---|---|
| 1 carat | 7.0 x 6.3 mm | 7,521 | $279 |
| 1.5 carat | 8.0 x 7.1 mm | 5,193 | $481 |
| 2 carat | 8.8 x 7.8 mm | 3,869 | $626 |
| 3 carat | 10.0 x 8.9 mm | 1,413 | $848 |
| 5 carat | 11.8 x 10.6 mm | 1,172 | $1,523 |
Heart shaped lab grown diamond prices
Today our heart shaped lab grown diamonds range from $183 to $494,678, across 27,789 stones. Carat weight makes the biggest difference, followed by color, clarity and cut. Prices step up at the whole and half carat marks, so a stone just over 1.00, 1.50 or 2.00 carats gives the size for the smallest premium.
Natural or lab grown?
A lab grown diamond has the same chemistry, hardness and sparkle as a natural diamond, at a fraction of the price, which is why it is a popular way to reach a larger size. From one carat up, our lowest priced heart shaped diamond today is $279 lab grown, against $1,139 natural. Compare heart shaped natural diamonds.
Choosing color and clarity
Up to about 1.5 carats, G or H color and VS2 or SI1 clarity usually look white and clean to the eye. From 2 carats color and inclusions are easier to see, so G or better and VS2 or better are worth considering.
Setting your diamond
Every diamond here can be set in an engagement ring, pendant or earrings made to order in our Bourton-on-the-Water workshop, hallmarked in the UK. Browse engagement rings or design your own. If the stone you want is not listed, our team can source it for you.
