4C's of Diamonds - Clarity

Understanding the clarity of a diamond is essential, as it directly impacts the gem’s appearance and value. Here’s what you should know about diamond clarity:

  1. Definition: Clarity refers to the absence of internal inclusions and external blemishes in a diamond. These imperfections can affect the diamond’s overall look and durability.

  2. Quality Grades: Diamond clarity is graded on a scale from Flawless (FL) to Included (I), with several sub-grades in between. The scale typically includes:

    • Flawless (FL): No inclusions or blemishes visible under 10x magnification.
    • Internally Flawless (IF): No inclusions and only minor blemishes visible under 10x magnification.
    • Very Very Slightly Included (VVS1 and VVS2): Inclusions are difficult to see under 10x magnification.
    • Very Slightly Included (VS1 and VS2): Inclusions are visible under 10x magnification but considered minor.
    • Slightly Included (SI1 and SI2): Inclusions are noticeable under 10x magnification.
    • Included (I1, I2, and I3): Inclusions are obvious under 10x magnification and may affect transparency and brilliance.

  3. Types of Inclusions and Blemishes: Common inclusions include crystals, feathers, clouds, and needles. Blemishes refer to surface imperfections like scratches and pits.

  4. Impact on Appearance: Higher clarity grades generally result in a more visually appealing diamond, as fewer inclusions mean a clearer and more brilliant stone. However, inclusions in lower clarity grades can sometimes be hidden by the diamond’s setting or are not visible to the naked eye.

  5. Impact on Price: Clarity significantly affects a diamond’s price. Flawless diamonds are exceedingly rare and command the highest prices. Diamonds with lower clarity grades are more affordable but may still look stunning, especially if the inclusions are not visible without magnification.

  6. Choosing the Right Clarity: When selecting a diamond, consider how visible the inclusions are to the naked eye, the diamond’s setting, and your budget. Many buyers opt for diamonds in the VS or SI range to balance quality and cost.

Understanding these aspects of diamond clarity will help you choose a stone that meets your aesthetic preferences and fits within your budget.
