Diamond Clarity

Flawless (FL), Internally Flawless (IF)

Internally Flawless (IF) diamonds may have external characteristics (also known as blemishes) that are extremely hard to see under 10x magnification.

In contrast, Flawless (FL) diamonds are the best clarity diamonds, as they show no inclusions or blemishes, even under intense magnification. These diamonds sit at the top of the diamond clarity scale, offering the highest clarity grade possible.

Very Very Slightly Included (VVS1, VVS2)

Very Very Slightly Included (VVS1, VVS2) diamonds earn their rating due to the presence of inclusions so small that they are difficult to spot even with a skilled grader using 10x magnification. While not as perfect as Flawless diamonds, VVS diamonds still fall within a high clarity range, making them highly sought after by diamond buyers.

Slightly Included (SI1, SI2, SI3)

Slightly Included (SI1, SI2, SI3) diamonds contain any type of inclusions that are noticeable to the naked eye, such as clouds, crystals, or feathers. These internal inclusions determine whether a diamond falls under the Slightly Included or Included categories. SI1 diamonds and SI2 diamonds are often valued for balancing price and appearance, with inclusions that are typically not visible unless examined closely.

Included (I1, I2, I3)

Included (I1, I2, I3) diamonds contain obvious inclusions that can be seen with the naked eye. These diamonds may lack transparency or brilliance due to excessive clouds, cavities, or large crystals. Despite having visible imperfections, Included diamonds remain popular for those looking for larger diamonds at a more affordable price.

Flawless Diamonds

If you’re looking for a beautiful diamond with few or no inclusions, diamonds in the Flawless (FL), Internally Flawless (IF), or VVS categories are ideal. Although they come at a premium, grades ensure that the diamond appears nearly perfect to the naked eye.

Choosing Very Slight Inclusions (VS)

Diamonds in the VS clarity range are considered high-quality but are more affordable than higher-clarity diamonds. They branch out into two categories: VS 1 and VS 2.

VS diamonds may contain minor inclusions that are not visible to the naked eye, making them a good choice for those seeking value without sacrificing appearance.

Slightly Included (SI)

SI1-SI2 diamonds are often seen as a great balance between value and quality. These diamonds contain noticeable inclusions under magnification, but they are typically clean diamonds to the naked eye. For those considering SI2 diamonds, consulting a skilled grader or diamond expert is recommended to ensure that inclusions aren’t too visible.

Going with a Large Diamond

For those who prioritize larger diamonds at lower prices, stones in the SI3-I1 clarity range are an option. However, these diamonds may have obvious inclusions that are visible without magnification, so it's important to consider how noticeable these inclusions are.

Location, Location, Location

The placement of inclusions within the diamond greatly impacts its clarity rating. Inclusions near the side facets of a diamond detract less from its appearance compared to those in the center. When reviewing a diamond clarity grade, take note of where the inclusions are located to ensure they won't affect the stone's brilliance.

Diamond Clarity FAQs

What are diamond inclusions?

Inclusions are natural imperfections within a diamond, often caused by trapped minerals or other particles during its formation. External imperfections, known as blemishes, occur during the cutting or polishing process.

Can inclusions be removed from a diamond?

No, diamond inclusions are permanent and cannot be removed. However, skilled diamond cutters can minimize the appearance of certain inclusions by carefully cutting and shaping the stone.

How important is diamond clarity?

While diamond clarity plays an important role in the diamond’s overall appearance, it’s just one of the many factors that contribute to a quality diamond. Clarity grades ensure diamonds are free from visible inclusions and blemishes, resulting in a cleaner and more brilliant appearance. That said, factors like diamond cut and diamond color are equally important in selecting a diamond.

Are inclusions always visible to the naked eye?

No, most diamond inclusions are only visible under 10x magnification. Diamonds with clarity grades of VS2 and higher are generally considered eye-clean, meaning that inclusions are not visible to the naked eye.

What does "eye clean" mean?

An eye-clean diamond shows no visible inclusions to the naked eye under normal lighting conditions. VS1 and VS2 diamonds are typically considered eye-clean, but this can vary depending on the viewer's standards.

How do gemologists determine diamond clarity?

Gemologists use 10x magnification to assess the presence of internal inclusions and external blemishes. Based on this evaluation, the diamond is given a clarity grading on the diamond clarity scale.

Does a higher clarity grade mean a more brilliant diamond?

Not necessarily. While a higher diamond clarity rating ensures fewer imperfections, a diamond’s brilliance is primarily affected by its cut. Even diamonds with lower clarity can sparkle brilliantly if they are well-cut.

Is it worth buying a flawless diamond?

While flawless diamonds are rare and highly valued, they come with a hefty price tag. Depending on your priorities, you may find that lower-clarity diamonds still offer exceptional beauty at a more affordable price.

What is the best clarity grade for an engagement ring?

The best diamond clarity grade for an engagement ring is one that offers a balance between clarity and price. VS1, VS2, and SI1 diamonds often provide great value, with clarity characteristics that are not visible to the naked eye.

Which diamond shapes hide clarity flaws the best?

Certain diamond shapes, such as brilliant cut diamonds, princess cut, and oval cut, are better at hiding inclusions due to their faceting styles. These shapes can help minimize the visibility of inclusions, especially in diamonds.
