Diamond Education

Diamonds are easiest to understand by breaking down its features into four C's: clarity, color, cut, and carats.


Clarity refers to tiny, natural imperfections, usually not visible to the unaided eye,    that occur in all but the finest diamonds.

FL, IF • Flawless, Internally Flawless

Flawless: No internal imperfections.

Internally Flawless: No internal or external imperfections.

VVS1, VVS2 • Very, Very Slightly Included

Very difficult to see imperfections under 10x magnification. An excellent quality diamond.

VS1, VS2 • Very Slightly Included

Imperfections are not typically visible to the unaided eye.

SI1, SI2 • Slightly Included

Imperfections are visible under 10x magnification, and may be visible with the unaided eye. 

I1 • Included

Minor inclusions that may be visible to the unaided eye.


After cut, color is the second most important feature to consider when purchasing   a diamond. The human eye detects the diamond's sparkle first, and the color second. The less color a diamond has, the higher the color grade.

A diamond's cut determines how much it will sparkle. Diamond shapes are available in a variety of cut grades, ranging from Ideal to Poor. A very good cut will reflect light that enters the diamond, while a poor cut would be a shallow or narrow diamond that will lose light.

The 58-facet round brilliant cut is the most popular because of its fire and brilliance, which is due to precise mathematical calculations. 

The cut of a diamond refers not only to the shape of the diamond and number of facets, but also to the quality of the cut. A diamond with uneven or poorly proportioned facets won't be given the same grade of cut as an ideally proportioned and masterfully cut stone.

Diamond Carat

A diamond's weight is measured in carats. Diamonds can range in size from a fraction of a carat to several carats. Given the rarity of large stones, however, the price of a diamond will quickly increase with size. It is rare to find a very large diamond with good color and clarity. To understand diamond size, consider carat weight and the diameter of the stone across the top (mm) and the diamond's cut grade.
