There are many factors that affect price and value of a 8 carat radiant cut diamond and no two radiants are the same, even if the specs on the certificate indicate that they should be.
Due to the high cost of these diamonds and the variation in size, shape and beauty that can be present in two diamonds with the same carat weight, we strongly recommend that you 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.
Our recommendation for this is Alon at The Diamond Oak, a third generation diamond dealer who puts a huge emphasis on personalised service and finding the right stone for each person.
Why working with a diamond specialist makes sense for such a significant investment
While smaller diamonds may be virtually interchangeable, at this carat weight there can be a significant different between two diamonds that look similar on paper.
Their specs may be similar but they are worth very different values.
A diamond specialist will take the time to understand what you are looking for, present several options (often sourced through personal connections and otherwise inaccessible) and guide you towards the diamond which is the absolute best fit for you.
8 carat radiant cut diamond price
As a broad range, the cost of a 8 radiant cut diamond (from those available at the time we were researching) can vary from $115,000 to $348,000.
To understand how much a 8 carat radiant cut diamond costs, we conducted research across three online diamond aggregation services which collectively have over 1,000,000 diamonds available to choose from, and then checked this against the most widely-accepted list of wholesale diamond prices.
It should be noted that VS1 clarity was the highest that we could find at the time of searching – there were no 8 carat radiant with IF or FL clarity grades. If you did find a 8 carat radiant cut stone with a top clarity grading, it’s likely that it would cost above $550,000
But even $115,000 to $348,000 is a significant range, and the price you will pay will depend on the color, clarity and the ‘make’ if the stone ie. how well the diamond has been shaped.
With diamonds, you generally get what you pay for, so ‘cheap’ 8 carat radiant cut diamonds will likely have a low-price for a reason – this may be significant inclusions (or ‘flaws’), or it may have poor proportions to reflect light and therefore not sparkle well.
But, when buying a diamond, there is always a balance that needs to be found between the 4Cs and the fifth C – cost. Where that balance lies for you is an individual choice, so it can be worth looking at a few options to where you are comfortable compromising, and where you aren’t.
How much do 8 carat radiant cut diamonds cost?
The table below will give you an idea of how color and clarity affect a 8 carat radiant cut diamond’s price:
If a price doesn’t appear, it means that no diamonds at that spec were available at the time this article was written.
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 8 carat radiant cut diamonds.
8 carat radiant cut diamond size
Radiant cut diamonds deliver the least ‘spread’ shapes of any diamond, which means that for a given carat weight, they appear smaller than many other shapes.
A typical A typical 8 carat radiant cut diamond may be around 11.56mm × 11.56mm × 7.4mm.
Here’s how it looks compared to a 7 carat and an 9 carat:
One important thing to understand when you are looking at 8 carat radiant cut 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.
Depending on the shape of the radiant cut, there can therefore be a significant difference in how large the diamond looks, even at the same carat weight.
This can be most noticeable when comparing square radiant cuts to more rectangular ones. A square radiant cut can ‘face up’ at a similar size to other square shapes like an asscher cut 8 carat diamond ring or a princess cut 8 carat diamond ring.
A rectangular radiant cut will often look larger than a square as they tend to be longer and narrower, and the often compare favourably to a cushion cut 8 carat diamond ring.
8 carat radiant 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:
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 8 carat princess cut 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 J without it looking yellow, as it will still look white compared to the warm tones of the setting.
8 carat radiant cut diamond clarity
Clarity is a measure of the presence of inclusions (or flaws) within a diamond.
The clarity scale runs:
Radiant cut diamonds are a ‘brilliant’ cut diamonds, which means that they are optimised to reflect light back from the bottom of the stone in the form of sparkle. This can mean that inclusions can be difficult to see under the facets, which is a good thing!
A good starting point for 8 carat radiant cut diamond 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.

8 carat radiant cut diamond solitaire ring
Solitaire settings are a great match for diamond solitaire ring diamonds – the simple style is a great pairing with the elegance of the diamond.
8 carat radiant cut 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.
8 carat radiant cut diamond three stone ring
Three stone three stone ring 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.
Best Place To Buy a 8 Carat Radiant Cut Diamond Ring
For smaller diamonds, I usually recommend buying online as retailers present hundreds of thousands of diamonds and make it easy to choose exactly what you are looking for.
However, As previously mentioned 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.
My recommendation is to find a diamond dealer that you can trust to guide you through this process. You may be able to source a personal recommendation, or my recommendation is Alon Mor at The Diamond Oak.
