Understanding Diamond Clarity

The clarity scale refers to the absence of inclusions or imperfections present within a cut diamond. Time and pressure within the earth is needed to make diamonds and when there has been enough of each, a flawless diamond is produced. They are extremely rare, even in the trade, and are usually found in royal jewel collections.

There is a sliding scale down from the perfect diamond to what is called “commercial quality” diamonds. They are grouped in a category called Included, divided into I1, I2 and I3. These are typically found on the high street and are often heavily included.

Inclusions are naturally occurring and happen when small specs of carbon or small air bubbles are left within the stone. Whilst regarded as flaws, inclusions aren’t always visible or unsightly. If they take on the form of a white inclusion, such as an air bubble or a feather – looks like a thin white line running through the diamond – they will not impede the passage of light and will sparkle as much as a less included diamond.
