One of the 4 C's: Clarity of Diamonds

Inspecting the Clarity of the Diamonds

Diamonds are graded on four key characteristics: cut, colour, carat, and clarity. While many focus on size or brilliance, clarity plays a crucial role in a diamond's overall beauty and value. But what exactly is clarity, and why does it matter? Let's delve into the world of inclusions and blemishes to understand this vital aspect of diamond grading.

What is Diamond Clarity?

Clarity refers to the absence of inclusions and blemishes in a diamond. Inclusions are internal characteristics, essentially tiny imperfections trapped within the diamond during its formation. Blemishes, on the other hand, are external imperfections found on the diamond's surface.

These imperfections can range from microscopic crystals and feathers to surface scratches and chips. The fewer and less visible these imperfections are, the higher the diamond's clarity grade.

The Clarity Grading Scale

The Gemological Institute of America (GIA) developed the most widely used clarity grading scale, which categorizes diamonds based on the visibility of these imperfections under 10x magnification. The scale is as follows:

• FL (Flawless): No inclusions or blemishes are visible under 10x magnification. These are exceptionally rare and highly prized.

• IF (Internally Flawless): No inclusions are visible under 10x magnification, but minor blemishes may be present on the surface.

• VVS1 and VVS2 (Very, Very Slightly Included): Inclusions are so minute that they are extremely difficult to see under 10x magnification. The difference between VVS1 and VVS2 lies in the size, number, and position of the inclusions.

• VS1 and VS2 (Very Slightly Included): Inclusions are minor and range from difficult to somewhat easy to see under 10x magnification.

• SI1 and SI2 (Slightly Included): Inclusions are noticeable under 10x magnification and may be visible to the naked eye in SI2 diamonds.

• I1, I2, and I3 (Included): Inclusions are obvious under 10x magnification and may affect the diamond's brilliance and transparency. In I3 diamonds, the inclusions can be quite significant.

Why Does Clarity Matter?

While carat weight often steals the spotlight, clarity significantly impacts a diamond's appearance and value.

• Brilliance and Sparkle: Significant inclusions can obstruct light as it passes through the diamond, reducing its brilliance and sparkle. A diamond with higher clarity allows light to travel more freely, resulting in a more vibrant display.

• Aesthetic Appeal: Visible inclusions can detract from a diamond's beauty. A clear diamond appears cleaner and more visually appealing.

• Value: Diamonds with higher clarity grades are rarer and therefore more valuable. Flawless and internally flawless diamonds command premium prices.

• Durability: While less common, very large or poorly placed inclusions can weaken a diamond's structure, making it more susceptible to damage.

Choosing the Right Clarity Grade

It's important to remember that most inclusions are microscopic and cannot be seen with the naked eye. Therefore, focusing on a clarity grade that offers the best balance between appearance and budget is crucial.

• For those seeking a flawless appearance, VS1 and VS2 diamonds are often a great choice. They offer excellent clarity without the premium price tag of FL or IF diamonds.

• SI1 diamonds can also be a good option, especially if the inclusions are well-dispersed and not easily visible to the naked eye - perhaps even covered by the setting.

• If you are on a budget, and the inclusion is not visible to the naked eye, a lower clarity grade can be a very good option.

  
  

Ultimately, the ideal clarity grade depends on personal preference and budget. By understanding the Four C's, the clarity grading scale and its impact on a diamond's appearance and value, you can make an informed decision and choose a diamond that suits you.
