4 C’s: Diamond Clarity

Clarity refers to the presence of inclusions in a diamond. Inclusions are natural identifying characteristics such as minerals or fractures appearing while diamonds are formed in the earth. Using 10x magnifying glasses, gemologists determine the size, type and position of inclusions.
The position of inclusions can affect the value of a diamond. Inclusions are ranked on a scale of perfection, known as clarity. This was established by the Gemological Institute of America (GIA). The clarity scale ranges from Fl (flawless) to I (included) and is based on the visibility at a magnification of 10x.
Within each clarity grade are sub categories ie. VVS, VVS1, Si1 or Si2. The numbers represent levels within each grade. The 1’s will be clearer (ie. have smaller or fewer inclusions) than the 2’s.
When light enters a diamond it is reflected and refracted out. Inclusions disrupt this flow of light and depending on the site and number of inclusions brilliance can be diminished.
The fewer inclusions the rarer the diamond. The flawless stones command the highest prices and moving down the scale the more included the stones, the lower their value.
Careful consideration to the number, size, brightness, nature and position of the inclusions must be taken. Inclusions that can be hidden at the edge of a diamond where it is set can have little effect on the beauty of the stone. This makes it more valuable and desired.
With so many varities of inclusions and the difficulty of understanding their relationship to the value of the diamond we recommend speaking to us for expert advice.
