When shopping for engagement rings, one of the most crucial factors to consider is diamond clarity. Diamond clarity significantly impacts the stone’s appearance and value, making it essential to understand what clarity is and how it is graded. This ultimate guide to diamond clarity will provide you with all the necessary information to make an informed decision when selecting a diamond for your engagement ring.

    What is Diamond Clarity?

    Diamond clarity refers to the presence of internal and external imperfections within a diamond. Internal imperfections, known as inclusions, and external imperfections, known as blemishes, are naturally occurring characteristics that result from the diamond’s formation process. Clarity determines how these imperfections affect a diamond’s overall appearance and brilliance.

    The GIA Clarity Scale


    The Gemological Institute of America (GIA) developed the most widely accepted diamond clarity grading scale. This scale ranges from Flawless (FL) to Included (I3) and includes the following grades:

    1. Flawless (FL): No inclusions or blemishes visible under 10x magnification.

    2. Internally Flawless (IF): No inclusions, only minor blemishes visible under 10x magnification.

    3. Very, Very Slightly Included (VVS1 and VVS2): Inclusions are very difficult to detect under 10x magnification.

    4. Very Slightly Included (VS1 and VS2): Inclusions are difficult to detect under 10x magnification.

    5. Slightly Included (SI1 and SI2): Inclusions are noticeable under 10x magnification but not typically visible to the naked eye.

    6. Included (I1, I2, and I3): Inclusions are obvious under 10x magnification and may affect transparency and brilliance.

    Factors Affecting Clarity

    Several factors influence a diamond’s clarity grade:

    1. Size: Larger inclusions and blemishes are more noticeable and can significantly impact clarity.

    2. Number: A higher number of imperfections can lower the clarity grade.

    3. Position: Inclusions located at the center or top of the diamond are more visible and detrimental than those on the sides.

    4. Nature: The type of inclusion or blemish affects clarity, with some types being more significant than others.

    5. Color and Relief: Darker inclusions contrast more with the diamond, making them more noticeable.

    Importance of Clarity in Engagement Rings

    While clarity is an essential aspect of a diamond’s quality, it’s important to balance clarity with other factors such as cut, color, and carat weight when selecting an engagement ring. In many cases, a diamond with a slightly lower clarity grade may still appear eye-clean, meaning imperfections are not visible to the naked eye. Prioritizing other factors, like cut, can often result in a more beautiful and brilliant diamond.

    Eye-Clean Diamonds

    An eye-clean diamond is one in which inclusions and blemishes are not visible without magnification. Many diamonds in the VS and SI clarity ranges can be eye-clean, offering a balance between quality and value. When shopping for an engagement ring, it’s beneficial to view diamonds in person or consult with a jeweler to ensure you’re choosing an eye-clean stone.

    Tips for Choosing the Right Clarity

    1. Set a Budget: Determine your budget and consider how clarity fits into your overall priorities.

    2. Balance with Other Factors: Remember that cut, color, and carat weight also significantly impact a diamond’s beauty.

    3. View the Diamond: Whenever possible, view the diamond in person or request detailed images and videos to assess clarity.

    4. Consult with Experts: Work with a reputable jeweler who can guide you through the selection process and provide expert advice.


     Understanding diamond clarity is crucial for making an informed decision when purchasing an engagement ring. By familiarizing yourself with the GIA clarity scale, recognizing the factors that influence clarity, and balancing clarity with other diamond characteristics, you can select a beautiful and valuable diamond for your engagement ring. Remember that eye-clean diamonds offer an excellent combination of quality and value, making them a popular choice for many couples. Whether you choose a Flawless diamond or one with minor inclusions, the most important aspect is finding a diamond that fits your preferences and budget, creating a timeless symbol of your love.
