Ultimate guide to buying a 10 carat pear diamond


10 carat pear diamonds are a beautiful choice – they combine the incredible sparkle of a brilliant cut with elongated elegance which looks incredible on the finger.

Pears are one of the less common choices for a 10 carat diamond, 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 10 carat pear diamond you see. This guide will help you avoid sub-par stones and ensure you get a beautiful and brilliant 10 carat pear diamond.

Key takeaway:

There are many factors that affect price and value of a 10 carat pear diamond – some obvious, some less so. Two stones that appear similar on paper may look surprisingly different in reality and be valued very differently.

If you’re not familiar with buying significantly sized diamonds, finding a trusted partner to guide you through the process will ensure you get the most beautiful diamond and pay a fair price.

10 carat pear diamond price

As a broad range, the cost of a 10 carat pear diamond can vary from $161,000 to $955,000.

carat pear diamond price

To understand how much a 10 carat pear 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.

$161,000 to $955,000 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’ 10 carat pear shaped 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 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.

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 L/W ratio) 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 10 carat pear diamonds.

10 carat pear diamond size


Pear diamonds are one of the ‘spreadiest’ shapes of any diamond, which means that for a given carat weight, they appear larger than other shapes.

A typical 10 carat pear diamond may be around 19.49mm × 11.74mm × 7.16mm.

Here’s how it looks compared to a 9 carat and a 11 carat:

10 carat pear diamond size comparison

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

This can mean that two 10 carat diamonds can actually appear very different sizes when set into a ring and viewed from the top.

Compared to other shapes, 10 carat pears generally look larger than the-closely related 10 carat heart diamond, but face up smaller than 10 carat oval diamond engagement rings or a marquise diamond at 10 carats, as pears are cut deeper.

10 carat pear diamond L/W ratio

Length-width ratio is, unsurprisingly, the ratio between the length and the width of a diamond:

This can hugely change what a pear shaped diamond looks like

For smaller pear diamonds, I usually recommend a L/W ration of 1.5:1, as this gives an elegant, elongated appearance.

However, for higher carat weights, a longer stone can look too large, and a shorter diamond may be preferable, both from a looks point of view, and cost.

Lower L/W ratio pear diamonds are generally priced lower that higher L/W ratios, as they use more of the rough diamond (which means less needs to be wasted) and there are more of them available (law of supply and demand coming into effect). 

At 10 carats, a L/W ratio of 1.4 – 1.45 will look great on the finger.

Watch out: poorly shaped diamonds

One thing to watch out for with higher carat weight pear shaped diamonds is that they may have been cut with a poor shape, just to make it to 10 carats in weight.

This can result in diamonds that are have overly round sides or square ends, which means that the diamond is heavier and just makes the 10 carat cut-off:

However, this usually results in a diamond that is not pleasing to the eye and we recommend that you aim for a diamond that hasn’t had these compromises made just to hit the desired carat weight.

10 carat pear 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:

10 Color scale

Higher carat weight diamonds tend to show up color more easily than smaller stones, especially in the corners where they sparkle less. With pear diamonds, this is a particular issue in the ‘point’ of the stone, where yellower colors are much more visible than at the other, more rounded end.

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 pear, 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.

10 carat pear diamond clarity

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

The clarity scale runs:

10 GIA diamond Clarity scale

Pear 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!

However, at the same time their elongated shape means they have a large ‘table’ (the flat area on the top of the diamond), which can mean that inclusions located here are easier to see. At higher carat weights, this issue is compounded as a bigger diamond means a bigger window where flaws can be seen.

A good starting point for 10 carat pear 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.

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

These images of 10 carat pear diamond rings on the finger will show you how big your ring could actually look.

Solitaire settings are a great match for pear 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 10 carat pear shaped diamond, I recommend you choose a band of at least 2.5mm width.

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

10 carat pear diamond halo ring

At 10 carats, some may feel that a halo is unnecessary to increase the size and impressiveness of the ring.

However, if you do choose a halo for your 10 carat pear ring, ensuring the side stones are a good match for the center stone is essential, due to their proximity.

Even more so than with a pavé or channel setting, working with someone who can color-match the side stones to the center stone is the best way to ensure that they complement each other well.

10 carat pear diamond three stone ring

Three stone [shape] 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.
