Heart shapes are one of the less common choices for a 6 carat engagement ring, which means that there may not be a huge selection available when you are looking.

However, that doesn’t mean that you should just settle for the first stone you see. This guide will help you avoid sub-par stones and ensure you get a beautiful and brilliant 6 carat heart diamond.

Key takeaway:

There are many factors that affect price and value of a 6 carat heart shaped diamond and no two heart shaped diamonds are the same, even if the specs on the certificate indicate that they should be.

While it is possible to buy from a large retailer like Brilliant Earth, it’s a better idea to work with a specialist in significantly-sized diamonds, who can guide you through the process and ensure you get the most beautiful diamond and pay a fair price.

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 6 carat princess cut brilliant diamonds.

6 Carat Heart Shaped Diamond Size


A typical A typical 6 heart diamond may be around 1192mm × 11.92mm × 7.15mm.

Here’s how it looks compared to a 5 carat and a 7 carat:

One important thing to understand when you are looking at 6 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 6 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 6 carat heart diamond will generally look smaller than its closely related cousin the 6 carat pear diamond ring, and significantly smaller than an elongated shape like a 6 carat marquise diamond ring.

6 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:

6 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 6 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.

6 Carat Heart Shaped Diamond Clarity

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

The clarity scale runs:

6 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 6 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.

Higher carat weight rings mean that additional considerations can be needed to be taken into account, depending on the ring setting style chosen.

Solitaire settings are a great match for heart diamonds – the simple style is a great pairing with the elegance of the diamond.

A major trend with settings is super slim and petite bands and prongs, which are effective in making the stone itself look larger.

While these can look great, some care does need to be taken with higher carat weights, as an extremely narrow band may not be wide enough to support the stone. It may twist on the finger and become uncomfortable.

If you’re choosing a solitaire setting to match a 6 carat heart diamond, I recommend you choose a band of at least 2.5mm width.

6 carat heart shaped diamond pavé ring

When choosing a pavé or channel setting, there is a big decision to make.

Either can be a great option, but one thing to consider is the color of the side stones.

Small, brilliant cut stones can appear whiter than larger diamonds, which means that even if you do match the color by the color grade, they still may appear whiter.

In cases like these, especially if you are going a little lower on the color on your center stone, like in the image above, it can be a good idea to work with an expert to ensure that the side stones complement the center stone.

Best Place To Buy a 6 Carat Heart Shaped Diamond Ring

For smaller carat weights, my recommended retailers are usually James Allen or Brilliant Earth. Both offer a huge selection of stones and high quality service.

They do also both offer 6 carat heart diamonds, and can be a good option if you are confident in making a decision yourself.
