Diamond clarity describes the natural characteristics visible within or on a diamond. Understanding clarity grades helps you compare stones thoughtfully while balancing appearance, rarity, and value.

Clarity refers to the presence of inclusions or imperfections within a diamond. Inclusions materialize within a diamond when tiny particles of gas, metal and dust are caught inside the structure as it grows. Blemishes affect the surface of the gem.

Diamonds with large inclusions and blemishes have poor clarity. Diamonds with small (or no) inclusions or blemishes have good clarity. The position, size and visibility of inclusions can have a huge impact on its clarity and price.

It’s important to note though: clarity has nothing to do with the brilliance and sparkle of a diamond. What could affect a stone’s sparkle factor is cut, which you can read more about under the ‘Cut’ article.

Clarity can impact the price of a diamond, which tends to be a top consideration for most diamond buyers. Only the most rare and expensive diamonds have no inclusions. Unless you recently won the lottery, you may want to find out more about optimizing clarity and minimizing cost!

A more affordable way to get diamonds with little to no inclusions is to go lab-grown. Lab-grown diamonds still have inclusions, but you'll more easily find diamonds with high clarity grades at an affordable price point.

No two diamonds are the same! It's crucial to examine a diamond closely before buying it using something like Keyzar's 3D preview tool. If inclusions are located in the table of a diamond, they will generally be easier to see. Even a small one could ruin your ring’s appearance.

Keep in mind that inclusions and blemishes may not be visible to the naked eye and only under the close inspection of a trained diamond-grader. Even if a trained eye were to find inclusions using a loupe, what matters most is that the stone is eye-clean. Many times, inclusions that are visible under a loupe are not visible to the naked eye.

A diamond that is 'eye-clean' is one that has no imperfections visible to the naked eye. This is the only thing you should be after (unless you’re a professional diamond trader). Spend your money on size, not on clarity. Go for the minimum clarity: eye-clean. SI1 diamonds are usually eye-clean but to make absolutely sure, use our 3D preview tool to see for yourself. If you go for a brilliant cut diamond, a below-SI1 clarity may not be an issue as the sparkle will obscure the inclusions and blemishes.

Low sparkle cuts like the Asscher generally need to have a higher clarity to avoid visible imperfections. For step-cuts, we don’t recommend going for clarity less than VS. If you want to splurge, we suggest doing so on cut; not on clarity.

If your cut is poor, it doesn’t matter how clean the diamond is. It’ll look lifeless and crummy. So don’t spend the bulk of your budget on clarity, allocate your budget mostly to cut and carat size.

Our advice is to aim for eye-clean diamonds in lower clarity grades. If you choose Keyzar, we recommend you to get in touch with us for advice on specific diamonds. We might help you save even more money by using prongs and bezels to hide light defects.

The good news is you don’t need to spend a fortune to find a high quality diamond with superb clarity and sparkle. You just need to consider the 4C’s: Cut, Clarity, Color and Carat Weight. Hopefully, you now have a better idea of how to find a beautiful diamond.

Carat weight is a universal unit of measurement in the jewelry industry. Contrary to what most people think, it doesn't refer to diamond size. It refers to diamond mass (i.e. weight).

Understanding the significance of carat weight can help you get a heavier, bigger-looking stone for less money. Missing the point on carat weight makes you vulnerable to overpaying for a scrawny, ugly-looking stone. Understanding diamond weight is that important. Below, we'll share everything you need to know carat weight. We'll cover size, price, quality, and more. Let's start with the basics.

What even is a carat? We're not talking about the preferred snack of your favorite cartoon rabbit. It's a unit of measurement specifically used for defining the weight of a gemstone. Adults usually think diamond carats are way more fun than rabbits' carrots…

In other words, a carat tells you something about a diamond’s size… But not in the way you might be expecting. Since carat weight is related to the length, width, and depth of a diamond, the relationship between carat weight and size is not directly 1:1. In the image above, the carat weight increases by 1 carat (that is, 0.2 grams) and increases in diameter only by 1.5mm. This is an example of how carat weight and length/width of the stone is not necessarily a 1:1 relationship.

(Note: the ratio between carat weight and stone dimensions also changes depending on stone shape. So, stone size increases at a different rate per carat in round versus oval stones)

Gemstones vary in density and anatomy. Rubies are usually cut to be deeper than diamonds. This means a 1 carat ruby will be a little smaller in dimensions than an equivalent diamond. This (or the contrary) is true for many other stones. Topaz is denser than diamonds, meaning it also looks smaller.

One carat weighs 0.2 grams, or 0.007 ounces. A diamond weighing 1 gram would be 5 carats. Now that's a big chunk of diamond! Diamonds are also referred to in points. 1 carat is 100 points, while a half-carat diamond might be called a 50-pointer diamond.
