It should be noted that VVS2 clarity was the highest that we could find at the time of searching – there were no 10 carat Asscher cut diamonds with IF or FL clarity grades. If you did find a 10 carat Asscher cut stone with a top color and clarity gradings, it’s likely that it would cost above $850,000.

That’s 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’ 10 carat Asscher cut diamonds will likely have a low-price for a reason – this may be significant inclusions (or ‘flaws’), yellow tinges of color or an undesirable shape.

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 is 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.

The table below will give you an idea of how color and clarity affect a 10 carat 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.

These prices are just guides, and factors such as the L/W ratio will affect the price of any individual stone, but should be a good guide to understand the relative pricing of different combinations of color and clarity for 10 carat Asscher cut diamonds.

One important thing to understand when you are looking at 10 carat Asscher 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.

Asscher cuts are the shape that is cut the deepest out of any diamond shape – they’re significantly deeper than the closely related 10 carat diamond ring in an emerald cut, or other square shapes like the 10 carat cushion cut diamond ring or a 10 carat diamond ring in a princess cut.

This means that there is less material available to spread out in the other directions. As a result, Asscher cut diamonds look smaller than most other diamond shapes at the same carat weight.

10 carat diamond color

As you likely know, diamond color is graded on a 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.

For most 10 carat diamonds though, I color is a good blend between being white enough so that it doesn’t look yellow, but also not paying more than you need to.

This applies equally to whether you are choosing a white colored setting (ie. platinum or white gold) or a yellow gold setting for your ring.

10 carat Asscher diamond clarity

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

The clarity scale runs:

EAsscher cut diamonds are a little different to most other shapes because they have a large, flat table on the top of the stone which can act like a window, making inclusions easier to see.

So, while with some other shapes, inclusions can be hidden under the angled top ‘crown facets’, Asscher cut diamonds don’t usually allow this.

At higher carat weights, this issue is compounded as a bigger diamond means a bigger window where inclusions can be seen.

A good starting point for 10 carat Asscher 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.
