Their specs may be similar but they are worth very different values.

With diamonds, you generally get what you pay for, so ‘cheap’ 4 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 4 carat diamond’s price:

4 carat Asscher cut diamond size

A typical A typical 4 carat Asscher cut diamond may be around 8.91mm × 8.91mm × 5.79mm.

Here’s how it looks compared to a 3 carat and a 5 carat:

4 carat asscher diamond size comparison

One important thing to understand when you are looking at 4 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 4 carat diamond ring in an emerald cut, or other square shapes like the 4 carat cushion cut diamond ring or a 4 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.

4 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:

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.

For most 4 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.

4 carat Asscher diamond clarity

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

The clarity scale runs:

diamond Clarity scale

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 4 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.

4 carat Asscher cut diamond solitaire ring

Solitaire settings are a great match for 4 carat Asscher cuts – 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 4 carat Asscher cut, I recommend you choose a band of at least 2.5mm width.

4 carat Asscher cut diamond pave ring

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

Should you go for an angular ‘stepped’ shape for the side stones, like emerald cuts, which complement the center stone’s shape, or should you go for brilliant cut diamonds like round or princess cut, which may give more sparkle?

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 step cuts, 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, it can be a good idea to work with an expert to ensure that the side stones complement the center stone.

Three stone Asscher cut rings look great when paired with other step cut diamonds, particularly trapezoid diamonds.

These complements the bold, art deco feel of the center stone and the tapered sizes work well with the angled corners of the Asscher itself.
