Is Clarity Important in a Diamond

Diamond clarity refers to the visual quality of the diamond, based on the amount of inclusions and blemishes. Inclusions may refer to foreign crystals within the transparent surface of the diamond, or small structural imperfections like cracks. Substantial inclusions can cause diamonds to have a milky or cloudy appearance. Blemishes, on the other hand, are imperfections that appear on the outer surface of the diamond. A clarity grade is assigned based on the appearance of the diamond under 10x magnification.

 

Smaller inclusions do not typically impact the ability of light to pass through a diamond, but large inclusions can prevent light from transmitting properly. The most valuable diamonds are referred to as Flawless (FL), because they have absolutely no inclusions or blemishes. Such diamonds are rare and coveted.

 

Overall, there are 10 clarity grades that a diamond can receive. Below FL is IF, or Internally Flawless, followed by Very, Very Small Inclusions (VVS1 and VVS2), Very Small Inclusions (VS1 and VS2), Small Inclusions (SI1 and SI2) and Imperfect (I1, I2 and I3).

What Is a Flawless Diamond?

 

A flawless diamond is truly a treasure in the gem world. To define it in technical terms, a flawless diamond must show no inclusions or blemishes under 10x magnification. In other words, a flawless diamond has nearly perfect clarity with absolutely no imperfections visible to the naked eye. If clarity is your prime concern, a flawless diamond is like the holy grail.

 

An internally flawless diamond contains no blemishes or inclusions on the inside, but contains minor flaws on the outside. These flaws can usually be removed with an expert polishing effort. A truly flawless diamond has no inclusions or blemishes on the inside or outside, just as the name suggests. Unfortunately, internally flawless and truly flawless diamonds are very rare, and very valuable, so if you're hoping to purchase one of these gems, be prepared to invest some serious money.
