When shopping for a diamond, clarity is one of the most significant factors influencing both the diamond's appearance and its value. Along with cut, colour, and carat weight, clarity makes up the "4Cs" established by the Gemological Institute of America (GIA) to standardize diamond quality.
In this guide, we'll break down the fundamentals of diamond clarity, explore the clarity grading scale, and discuss how clarity impacts diamond selection and pricing.
What is Diamond Clarity?
Diamond clarity measures the presence of internal or external flaws—known as inclusions and blemishes—found within or on the surface of a diamond. These imperfections occur naturally, as diamonds form under intense heat and pressure deep within the earth. Clarity grades reveal how visible these imperfections are under magnification and sometimes with the naked eye.
Inclusions and blemishes influence the diamond's brilliance, structure, and beauty. Generally, the fewer the inclusions, the higher the clarity grade, leading to a more desirable and valuable diamond.
Understanding Inclusions and Blemishes
- Inclusions: Internal flaws, such as black or white spots, cracks, and cavities, occur within the diamond. Examples include crystals, feathers, and needles.
- Blemishes: These are surface imperfections, such as scratches or chips, typically caused during the cutting process or from wear over time.
The Diamond Clarity Grading Scale
The GIA developed an industry-standard clarity grading scale to classify diamonds based on the type, size, and visibility of inclusions and blemishes. Here’s an overview of the clarity grades:
-
Flawless (FL):
No inclusions or blemishes are visible under 10x magnification. FL diamonds are exceptionally rare and costly. -
Internally Flawless (IF):
No inclusions are visible under 10x magnification, though minor blemishes may be present on the surface. -
Very, Very Slightly Included (VVS1 and VVS2):
Contains tiny inclusions that are difficult to detect even under 10x magnification. These diamonds appear flawless to the naked eye. -
Very Slightly Included (VS1 and VS2):
Contains small inclusions that may be seen under magnification but are generally not visible to the naked eye. -
Slightly Included (SI1 and SI2):
Inclusions are noticeable under magnification and can sometimes be visible to the naked eye, particularly with SI2 diamonds. -
Included (I1, I2, I3):
Contains inclusions that are obvious under 10x magnification and are typically visible to the naked eye. These inclusions can impact durability and brilliance.
Choosing the Right Clarity Grade for Your Diamond
Balancing clarity with other factors like carat weight, colour, and cut can help maximize both beauty and value. Here are a few considerations to keep in mind:
- Budget-Friendly Options: For those on a budget, SI or VS clarity grades offer an attractive balance of appearance and affordability, especially when inclusions are hard to detect without magnification.
- Focus on Eye-Clean Diamonds: A diamond is considered “eye-clean” when inclusions are not visible to the naked eye. Diamonds graded VS1 or VS2, and sometimes even SI1, are typically eye-clean and present a sparkling appearance at a lower price than higher-clarity grades.
- For High-End Jewellery: If investing in a high-value piece, opting for VVS or IF clarity grades offers a near-flawless appearance, contributing to both prestige and long-term investment value.
Does Clarity Affect Diamond Sparkle?
While clarity plays a role in a diamond’s brilliance, it’s not the only factor. A well-cut diamond will reflect light beautifully, even if it has a lower clarity grade, as many inclusions do not hinder light performance. However, very visible inclusions can interrupt light reflection, diminishing sparkle.
How Clarity Impacts Diamond Price
Higher clarity diamonds are rarer, making them more valuable and costly. Flawless (FL) and Internally Flawless (IF) diamonds command the highest prices due to their scarcity. Meanwhile, Slightly Included (SI) or Included (I) diamonds are more affordable, making them popular among budget-conscious shoppers.
Additional Tips for Buying a Diamond Based on Clarity
- Consult a Professional: A certified gemologist or jeweller can provide insights and help you evaluate the clarity grade to find the best diamond within your budget.
- Focus on Certified Diamonds: Purchase diamonds with a grading report from reputable institutions like GIA or AGS, which verify the clarity grade.
- Choose the Right Setting: Intricate or halo settings can conceal minor inclusions, allowing you to choose a lower clarity grade without compromising beauty.
- Consider Personal Preferences: Ultimately, choose a clarity grade that meets your aesthetic preferences, budget, and the intended purpose of the diamond.
Key Takeaways on Diamond Clarity
- Definition: Diamond clarity measures the presence of internal (inclusions) and external (blemishes) imperfections, affecting the diamond's appearance and value.
- Types of Flaws:
- Inclusions: Internal flaws like crystals and feathers.
- Blemishes: Surface imperfections like scratches or chips.
- Clarity Grading Scale: The GIA's clarity scale ranges from:
- Flawless (FL): No inclusions or blemishes visible under 10x magnification.
- Internally Flawless (IF): No inclusions; minor surface blemishes may be present.
- Very Slightly Included (VVS1/VVS2): Tiny inclusions difficult to detect.
- Slightly Included (SI1/SI2): Inclusions noticeable under magnification; may be visible to the naked eye.
- Included (I1/I2/I3): Obvious inclusions affecting durability and appearance.
- Choosing Clarity:
- Opt for SI or VS clarity grades for a good balance of quality and price.
- Look for “eye-clean” diamonds where inclusions are not visible without magnification.
- Impact on Sparkle: Clarity affects brilliance; however, a well-cut diamond can still sparkle beautifully despite minor inclusions.
- Price Considerations: Higher clarity diamonds (FL, IF) are more expensive due to rarity, while lower clarity diamonds (SI, I) are more budget-friendly.
- Professional Guidance: Consult a gemologist or buy certified diamonds to ensure clarity grading accuracy and make informed purchasing decisions.
- Personal Preference: Choose a clarity grade based on aesthetic preference, budget, and the diamond’s intended purpose (e.g., engagement ring, investment piece).
Conclusion
Diamond clarity is an essential aspect of diamond quality, playing a crucial role in determining a diamond’s value and beauty. Understanding the clarity grading scale helps buyers make informed decisions, balancing beauty and budget to find the perfect diamond.
Whether choosing an investment piece or a stunning engagement ring, understanding diamond clarity can ensure you get the best value for your purchase.
