It’s important to recognise that at this carat weight, there can be considerable differences between individual stones with similar specs on paper, so these are very much just a guide.

Factors such as availability at the time you are looking, and then specific of the individual diamond (e.g. the cut quality) will affect the price of any individual stone. However, the prices quoted should be a good guide to understand the relative pricing of different combinations of color and clarity for 7 carat princess cut brilliant diamonds.

7 Carat Heart Shaped Diamond Size


A typical A typical 7 heart diamond may be around 12.55mm × 12.55mm × 7.53mm.

Here’s how it looks compared to a 6 carat and an 8 carat:

One important thing to understand when you are looking at 7 carat heart shaped diamonds is that carat weight is a measure of weight rather than size.

Carat weight is therefore spread out throughout the volume of the stone ie. length, width and depth. A shallower 7 carat heart diamond may therefore have more material available to increase it’s length and width, resulting in a stone that looks larger when viewed from above.

A 7 carat heart diamond will generally look smaller than its closely related cousin the 7 carat pear diamond ring, and significantly smaller than an elongated shape like a 7 carat marquise diamond ring.

7 Carat Heart Shaped Diamond Color

As you likely know, diamond color is graded on a GIA-developed scale from D to Z, although most diamonds used in jewelry fall into the D to M range:

7 Color scale

Higher carat weight diamonds tend to show up color more easily than smaller stones, especially in the corners where they sparkle less.

If you want to ensure your diamond doesn’t have a yellow tint, it’s important to try and keep the color as high up the scale as possible.

On the other side of the equation is the effect color has on price.

In most shapes, the price difference between an H color, I color and J color diamond can be significant,

With a 7 carat heart diamond, the color grade you choose can be dependant on the color of the ring setting you are going to pair the diamond with. If you are choosing a white colored setting (platinum or white gold), then I color delivers a good balance of white appearance and value.

However, if you are choosing a yellow gold setting, then you can reduce the color of your diamond to K without it looking yellow, as it will still look white compared to the warm tones of the setting.

7 Carat Heart Shaped Diamond Clarity

Clarity is a measure of the presence of inclusions (or flaws) within a diamond.

The clarity scale runs:

7 GIA diamond Clarity scale

Heart diamonds are a brilliant cut, which means that they are optimised to reflect light back from the bottom of the stone in the form of brilliant sparkle. This can mean that inclusions can be difficult to see under the facets, which is a good thing!

A good starting point for 7 carat heart shaped clarity is SI1:

However, depending on the diamonds that are available at the time you are looking, you may need to increase this to VS2, or even higher, to ensure that the diamond is ‘eye clean’ and no flaws can be seen.

Three stone [shape] rings look great when paired with almost any other shape as the side stones.

Tapered side stones can work particularly well because the side stones make the transition from the long broad side of the diamond to the narrow band more gentle and more elegant.

7 carat heart shaped diamond halo ring

At 7 carats, some may feel that a halo is unnecessary to increase the size and impressiveness of the ring.

However, if you do choose a halo ensuring the side stones are a good match for the center stone is essential, due to their proximity.

Even more so than with a pavé or channel setting, working with someone who can color-match the side stones to the center stone is the best way to ensure that they complement each other well.

Best Place To Buy a 7 Carat Heart Shaped Diamond Ring

For smaller carat weights, my recommended retailer is frequently James Allen, which offers a huge selection of stones and can be a good option if you are confident in making a decision yourself.

However, buying a diamond of this size diamond is very different to buying a smaller stone – both in the expense involved and in the potential for pitfalls.

If you feel that you would like some assistance with the purchase (and at this carat weight, that can be a good idea), my recommendation is Alon Mor at The Diamond Oak.
