10 carat princess cut diamonds are a beautiful choice – they sparkle incredibly well, which means that your ring will catch eyes from across any room!

Key takeaway:
There are many factors that affect price and value of a 10 carat princess cut diamond – some obvious, some less so. Two stones that appear similar on paper may look surprisingly different in reality and be valued very differently.
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.
How much do 10 carat princess cut diamonds cost?
10 carat princess cut diamonds are extremely rare, so the price of an individual stone will depend on the 4 C quality factors, as well as how well the stone has been shaped.
It’s likely that the price could range from $200,000 for a diamond with low color and clarity (e.g. SI2 clarity, K color) all the way to around $800,000 for a diamond with high colour and clarity (e.g. FL clarity, D color)
It’s important to recognise that at this carat weight, there can be considerable differences between individual stones with similar specs on paper, so each stone really does need to be assessed on its own basis.
10 carat princess cut diamond size
A typical 10 carat princess cut diamond may be around 11.87mm x 11.87mm x 8.55mm.
Here’s how it looks compared to a 9 carat and an 11 carat:
One important thing to understand when you are looking at 10 carat princess 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.
Princess cuts are cut to be deeper than many other diamond shapes, which means that there is less material available to spread out in the other directions.
A princess cut will look larger than most asscher cut diamonds at 10 carats, but will look smaller than a square-ish 10 carat radiant cut diamond ring or a square 10 carat cushion cut engagement ring.
10 carat princess cut 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 10 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 K without it looking yellow, as it will still look white compared to the warm tones of the setting.
10 carat princess cut diamond clarity
Clarity is a measure of the presence of inclusions (or flaws) within a diamond.
The clarity scale runs:
Princess cut 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 10 carat princess 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.
Best Place To Buy a 10 Carat Princess Cut Diamond Ring
For smaller carat weights, my recommended retailers 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, they don’t offer diamonds at this carat weight, so my strong recommendation is to find a reputable diamond dealer who can assist you with sourcing your diamond. My recommendation is Alon Mor at The Diamond Oak.
