Diamond Clarity

Diamond clarity refers to the assessment of a diamond's internal and external characteristics, often referred to as "inclusions" and "blemishes," respectively. These characteristics can affect a diamond's overall beauty, transparency, and value. The diamond clarity grading system is a standardized way of categorizing and communicating the presence and visibility of these imperfections in a diamond.

 

Here's an overview of the diamond clarity grading system:

  •  **Flawless (FL)**: This is the highest clarity grade and indicates that no internal or external imperfections are visible under 10x magnification. Flawless diamonds are exceedingly rare and highly valuable.

 

  •  **Internally Flawless (IF)**: Internally Flawless diamonds have no internal imperfections visible under 10x magnification but may have minor blemishes on the surface. IF diamonds are also highly prized.

 

  •  **Very Very Slightly Included (VVS1 and VVS2)**: Diamonds in this category have tiny inclusions that are extremely difficult to detect even under 10x magnification. VVS diamonds offer excellent clarity and are considered of very high quality.

 

  •  **Very Slightly Included (VS1 and VS2)**: VS diamonds have small inclusions that are visible under 10x magnification but are usually challenging to see with the naked eye. These diamonds provide good clarity and are an excellent choice for most consumers.

 

  •  **Slightly Included (SI1 and SI2)**: SI diamonds have noticeable inclusions that are easily visible under 10x magnification and may be visible to the naked eye. However, SI2 diamonds have more noticeable inclusions than SI1. These diamonds represent a good balance between value and clarity.

 

  • **Included (I1, I2, and I3)**: Diamonds in this category have inclusions and blemishes that are visible to the naked eye. I1 diamonds have minor inclusions, while I2 and I3 diamonds have more substantial and more numerous imperfections. I-clarity diamonds are the lowest on the clarity scale and are typically the least valuable.


Diamond clarity is one of the "Four Cs" used to assess a diamond's quality, alongside carat weight, color, and cut. The specific clarity grade assigned to a diamond is determined by a trained gemologist who examines the stone under 10x magnification and assesses the size, location, number, and visibility of any imperfections. In practice, many consumers find diamonds in the VS1 to SI2 range to offer a good balance between quality and cost, as these diamonds often appear eye-clean, meaning the inclusions are not visible to the naked eye. However, the choice of diamond clarity should be made based on individual preferences and budget.
