Summary
Diamond clarity plays an important role in a diamond’s appearance and value, but there is no single clarity grade that is best for every buyer. The ideal clarity depends on factors such as diamond size, shape, budget, and whether inclusions are visible to the naked eye. Understanding how diamond clarity is graded can help you select a beautiful diamond that balances quality, value, and personal preferences.
Choosing a diamond often involves learning a new vocabulary of grading terms, and clarity is one of the most important factors to understand. Clarity grades help describe the natural characteristics found within a diamond and can influence both its appearance and price. While shoppers frequently compare grades such as VS1 and SI1, these are only part of a much broader clarity scale. Understanding how clarity works can help you make a more informed decision when selecting a diamond for an engagement ring or fine jewelry piece.
What Is Diamond Clarity?
Diamond clarity refers to the presence of natural inclusions and surface blemishes that form during a diamond’s creation.
Because diamonds form deep within the earth under intense heat and pressure, most contain tiny internal characteristics known as inclusions. Some may also have external blemishes that developed during the cutting and polishing process. Gemologists evaluate these characteristics based on their size, location, visibility, and number when assigning a clarity grade.
Clarity is one of the 4Cs of diamond grading, alongside cut, color, and carat weight. While clarity contributes to a diamond’s overall quality, it is only one factor among several that determine a diamond’s beauty and value.

Understanding the Diamond Clarity Scale
The diamond clarity scale ranges from flawless diamonds with virtually no visible characteristics to diamonds with inclusions that are more easily seen under magnification.
The most commonly encountered clarity grades include:
- FL (Flawless)
- IF (Internally Flawless)
- VVS1 and VVS2 (Very Very Slightly Included)
- VS1 and VS2 (Very Slightly Included)
- SI1 and SI2 (Slightly Included)
- I1, I2, and I3 (Included)
Many engagement ring shoppers focus on the middle of the scale because it often provides the best balance between appearance and value. VS1 and VS2 diamonds typically contain minor inclusions that are difficult to detect under magnification, while SI1 and SI2 diamonds may contain more noticeable inclusions depending on their size and location.
The key distinction is that clarity grades are determined under 10x magnification. In everyday wear, many diamonds with lower clarity grades can still appear visually clean to the naked eye, particularly when they have excellent cut quality.
How Much Clarity Do You Really Need?
The best diamond clarity grade is often the one that looks beautiful to your eye while fitting comfortably within your budget.
Many buyers assume they need the highest clarity possible, but that is not always necessary. In fact, choosing a slightly lower clarity grade can allow you to invest more in cut quality or carat weight, both of which may have a greater impact on a diamond’s overall appearance.
The table below provides a general overview of popular clarity grades:
| Clarity Grade | Typical Appearance | Value Consideration |
| VS1 | Very clean, inclusions difficult to find | Premium option |
| VS2 | Usually eye-clean, excellent balance | High value |
| SI1 | Often eye-clean when carefully selected | Popular value choice |
| SI2 | May show visible inclusions depending on the diamond | Budget-friendly option |
The right clarity grade ultimately depends on the individual diamond. Two diamonds with the same clarity grade may appear different depending on the type and placement of their inclusions. This is why working with an experienced jeweler can be valuable when comparing options.
