Picture yourself holding a tiny piece of the Earth's geological history in your hand – a dazzling diamond. These gemstones, formed under intense pressure deep within the Earth, captivate us with their exquisite beauty and brilliance. However, hidden within each diamond are secrets: tiny marks and imperfections known as inclusions. Understanding diamond clarity is the key to appreciating a diamond's unique character and finding your perfect treasure – whether it's a timeless jewel or the heart of an unforgettable engagement ring.
Diamonds undergo a remarkable journey, formed amidst the Earth's intense heat and pressure. This process often leaves behind minuscule internal marks called inclusions, which are a testament to the diamond's creation. Alongside these internal features, surface imperfections known as blemishes contribute to a diamond's clarity grade. Clarity is a crucial factor in determining a diamond's value; diamonds with fewer and smaller inclusions typically command higher prices. However, grasping clarity enables you to strike a balance between beauty and budget when choosing your diamond.
This guide aims to unlock the mysteries of diamond clarity, empowering you to make informed decisions and discover the diamond that perfectly reflects your style and preferences. Whether you're in search of the ideal engagement ring or a captivating piece of jewelry, understanding clarity is essential for finding a diamond that truly shines. Here is everything you need to know about diamond clarity.

What Is Diamond Clarity?
Diamond clarity refers to the relative presence or absence of internal imperfections (inclusions) and external imperfections (blemishes) that contribute to the gem’s overall clarity. Diamond inclusions form during their crystallisation under immense heat and pressure, often appearing as tiny crystals, feathers, pinpoint marks, or cloud-like features. Think of them as the diamond's unique birthmarks. Blemishes, on the other hand, can be found on the diamond's surface, such as scratches, pits, or nicks.

Diamond Clarity Grades
The Gemological Institute of America (GIA), a global gemmological institute and authority in the world of gemstones, developed the globally recognised standard for diamond grading. Their system offers a precise and objective way to assess a diamond's clarity, and is used globally to assess the clarity as well as the overall diamond quality. Here's an in-depth look at the GIA clarity scale's 6 categories and their sub-grades:
- Flawless (FL): Diamonds in this category are exceptionally rare. Even under 10x magnification, a skilled grader will find no inclusions or blemishes. These gemstones are highly prized for their exquisite beauty and command premium prices.
- Internally Flawless (IF): Like flawless diamonds, no inclusions are visible under 10x magnification. However, internally flawless diamonds may exhibit very minor surface blemishes, which generally do not impact their beauty.
- Very Very Slightly Included (VVS1, VVS2): Inclusions in diamonds of this grade are extremely difficult to detect, even for a trained grader using 10x magnification. These inclusions are minuscule and have a negligible effect on the diamond's overall appearance. A VVS1 clarity grade for a diamond is considered higher than a VVS2 clarity grade.
- Very Slightly Included (VS1, VS2): Diamonds within this category possess inclusions that, while detectable under magnification, are typically challenging to see with the naked eye. These inclusions are usually minor and do not significantly detract from the diamond's beauty. A VS1 grade is higher than a VS2 grade.
- Slightly Included (S1, S2): Inclusions in SI-graded diamonds become noticeable under magnification. Depending on their size, nature, and positioning, these inclusions might also be visible to the naked eye. However, they generally do not significantly hinder the diamond's overall appearance.
- Included (I1, I2, I3): Diamonds falling within this category have inclusions that are easily visible to the naked eye. These inclusions can impact the gemstone’s transparency and even its structural integrity to varying degrees.

Decoding Diamond Clarity
The GIA clarity grading scale, along with a detailed grading report, empowers you to understand the unique characteristics of your diamond. When buying diamonds, pay close attention to the clarity grade, but also keep in mind that other factors like the diamond shape, cut, colour, and carat weight all play a vital role in a diamond's overall beauty and value, as they interact with clarity in a complex and beautiful way. In a general sense, the 4Cs of diamonds is a globally used framework that helps one ascertain the overall quality and value of a diamond.
How Clarity Affect a Diamond’s Appearance
The phrase "eye-clean" is essential for diamond buying. An eye-clean diamond means no inclusions are visible to the naked eye when viewed from the top. Clarity grade, combined with the size, colour, and positioning of the inclusions, determines eye cleanliness. A diamond's inclusion may only be visible under magnification but not discernible to the naked eye.
Additionally, clarity is just one part of the equation for revealing a diamond's beauty. A diamond cut with ideal proportions is paramount to maximising a diamond's splendour, fire (its ability to disperse light into rainbow colours), and scintillation (that dazzling sparkle). In fact, an expertly executed diamond cut can often make subtle inclusions far less noticeable.
Assessing Diamond Quality
Understanding diamond clarity is an empowering first step, but true mastery lies in balancing it with the other of the 4Cs - cut, colour, and carat weight. Remember, there's no single "perfect" diamond, and the right combination of these factors, including the diamond shape, depends on your priorities and preferences.
- The Color: Diamond color (for white/colorless diamonds) is graded on a scale from colourless (D) to those with noticeable yellow tints (Z). While colourless diamonds are highly prized, diamonds in the near-colourless range (G-J) can offer exceptional beauty while still being more budget-friendly. If a hint of warmth doesn't bother you, opting for a diamond color with a slightly lower grade can free up resources for other priorities such as clarity, cut, size, and diamond shape.
- The Cut: A diamond's cut isn't just about its shape (round, oval, etc.). It refers to the proportions, symmetry, and polish that determine a stone's sparkle, fire, and scintillation. An exceptional cut can make a diamond with minor inclusions appear more radiant than a higher clarity stone with a poor cut. Prioritising the cut will maximise your diamond's beauty and sparkle.
- The Carat Weight: Diamond size is measured in carats. If you dream of a show-stopping diamond, consider balancing clarity with a larger stone. Be sure that the diamond's clarity grade does not significantly compromise its overall beauty.

Beyond Diamond Clarity
- Clarity Enhancements: The pursuit of perfection has led to techniques aimed at improving the apparent clarity of lower-grade diamonds. Treatments like fracture filling (where glass-like material fills surface-reaching cracks) or laser drilling (creating microscopic channels to reach and remove dark inclusions) can temporarily make inclusions less noticeable. However, these enhancements are controversial and may impact a diamond's long-term durability - potentially diminishing its value. It's crucial to be aware of these practices and always insist on full disclosure. When considering treated diamonds, be sure to weigh the potential benefits against the long-term implications.
- Significance of Treatment Disclosures: Reputable jewellers will always disclose if a diamond has undergone clarity enhancement. Look for a grading report from the GIA or other reputable gemological laboratories that will clearly state any treatments a diamond has received. This transparency is particularly important for significant purchases like engagement rings or investment-grade diamonds.
Advanced Considerations - Mapping Inclusions & Choosing the Right Diamond
A diamond's clarity grading report, especially from reputable labs like the GIA, often includes a "clarity plot". This invaluable diagram maps the location, size, and type of inclusions (and sometimes blemishes) within your diamond. Inclusions are like fingerprints, with each plot being utterly unique to the stone. Understanding your diamond's plot adds a deeper dimension to its clarity grade. Here's why it matters:
- Position is Key: The location of an inclusion significantly impacts its visibility. An inclusion near the edge of a diamond (the girdle) is generally less noticeable than one closer to the centre (the table). Likewise, an inclusion hidden under a facet might be far less noticeable compared to one in the open table area. This directly impacts the diamond clarity grade assigned to your stone. This is where faceting comes into play: skilled diamond cutting strategically places facets for maximum sparkle and can sometimes cleverly camouflage minor inclusions.
- Type & Color of Inclusions: Inclusions come in various forms like crystals, feathers, clouds, and more. Some inclusions are more obvious than others. Additionally, the colour of an inclusion may influence its visibility, with dark inclusions being easier to spot than lighter ones.
Pointers For Diamond Selection
- Engagement Rings: Eye-cleanliness is often prioritised for engagement rings, ensuring no inclusions are visible to the naked eye when viewed from above. VS1 or VS2 clarity grades generally offer exceptional beauty and value. If seeking absolute perfection, consider VVS or even FL diamonds.
- Everyday Jewelry: For earrings, pendants, or other jewelry pieces where the diamond might not be the sole focus, slightly included diamonds (SI1 or SI2) can be stunning options without sacrificing significant sparkle. Furthermore, some jewellery settings can cleverly mask minor inclusions.
- Maximising Brilliance: Remember, a diamond's cut is paramount for maximising sparkle. A masterfully cut diamond can outshine a higher-clarity diamond with a mediocre cut. If sparkle and fire are your top priorities, focus on the cut and balance that with a clarity grade that fits your preferences.
- Budget Considerations: Clarity significantly impacts diamond prices. Prioritising a diamond's cut and cleverly balancing the other "C"s can unlock the best value for your budget while finding a diamond that perfectly reflects your individual style.
