Lab diamonds, also known as lab-grown or synthetic diamonds, have become increasingly popular over the years due to their ethical and sustainable nature. These diamonds are created in a controlled laboratory environment using advanced technology that replicates the natural conditions required for diamond formation. One of the key factors that determine the quality and desirability of a lab-grown diamond is its clarity. In this article, we explore the different clarity grades of lab diamonds and answer the question: what is the highest clarity lab diamond?

The Clarity Grading Scale

Before delving into the highest clarity grade of lab diamonds, it is essential to understand the clarity grading scale used to assess diamonds. The Gemological Institute of America (GIA), a renowned authority in gemology, developed the most widely accepted and used clarity grading system for diamonds. The scale ranges from Flawless (FL) to Included (I), with various gradations in between. Each clarity grade reflects the presence of internal or external flaws, known as inclusions and blemishes, respectively.

Symbolizing Clarity: FL

The highest clarity grade on the GIA scale is Flawless (FL). Diamonds in this category are exceptionally rare and free from any visible inclusions or blemishes when examined under 10x magnification. These diamonds exhibit unparalleled brilliance and light reflection due to their flawless nature. While natural FL diamonds are incredibly rare and command a premium price, lab-grown diamonds offer an opportunity for consumers to possess stones with the same level of clarity at a more affordable cost.

Incredible VVS Clarity

One of the most sought-after clarity grades in lab diamonds is Very, Very Slightly Included (VVS). The VVS clarity grade is divided into two subcategories: VVS1 and VVS2. Diamonds in this grade usually have extremely minute inclusions that are challenging to detect even under 10x magnification. These inclusions are often microscopic pinpoints or tiny crystals that are inconspicuous to the naked eye and have minimal impact on the diamond's appearance and overall brilliance.

Lab diamonds with VVS clarity are highly desirable due to their exceptional clarity characteristics. They offer a visually flawless appearance, reflecting light to create breathtaking scintillation. The VVS clarity grade is an excellent choice for those seeking a diamond with exceptional clarity while still maintaining value for money compared to the higher clarity grades.

Eye-Catching VS Clarity

Moving down the clarity scale, we reach the Very Slightly Included (VS) grade. Like VVS, this grade is further divided into two subcategories: VS1 and VS2. Diamonds in the VS clarity grade display minor inclusions that are relatively more noticeable under 10x magnification compared to VVS diamonds. However, these inclusions remain invisible to the naked eye, ensuring the diamond's beauty remains uncompromised.

Lab diamonds with VS clarity offer a fantastic balance between clarity and value. They provide an excellent option for those seeking a visually stunning diamond that offers a high level of clarity while keeping the cost relatively more affordable than the higher clarity grades. VS clarity diamonds can appear eye-clean, making them a popular choice for quality-conscious purchasers.

SI Clarity: Slightly Included Yet Stunning

Moving further down the clarity grading scale, we come to the Slightly Included (SI) grade. Like the previous grades, SI is also divided into two subcategories: SI1 and SI2. Diamonds with SI clarity possess visible inclusions under 10x magnification. However, these inclusions are still quite small and do not detract significantly from the diamond's overall beauty.

SI clarity lab diamonds offer an excellent value proposition for those looking to maximize their budget without sacrificing the diamond's visual appeal. While some inclusions may be more noticeable, they often remain invisible to the naked eye. SI clarity diamonds can still exhibit remarkable fire and brilliance, making them an attractive option for those seeking an affordable yet stunning lab-grown diamond.

I Clarity: Inclusions without Impact

Finally, on the clarity grading scale, we have Included (I) diamonds. This category is partitioned into three subcategories: I1, I2, and I3. While I diamonds possess visible inclusions both under 10x magnification and to the naked eye, they can still be prized for their unique beauty and affordable price point.

Lab diamonds with I clarity may have several inclusions that affect their overall appearance. However, these inclusions can be dispersed throughout the stone or concentrated in specific areas, and they may even resemble patterns or celestial phenomena. Some individuals appreciate the organic and natural charm that these unique inclusions bring to the diamond.


In conclusion, the highest clarity grade for lab diamonds is Flawless (FL), representing diamonds that are entirely free from inclusions and blemishes. However, for those seeking a balance between clarity and cost-effectiveness, Very, Very Slightly Included (VVS), Very Slightly Included (VS), Slightly Included (SI), and Included (I) diamonds offer numerous options to suit a range of preferences and budgets. Each clarity grade possesses its distinct beauty and allure, making lab-grown diamonds an excellent choice for those seeking ethically sourced and high-quality diamonds. Whether you desire a flawless diamond or prefer the charm of unique inclusions, lab diamonds provide an array of choices to meet your specific needs and style.
