Flawless gemstones are very rare and valuable, and even many of the world’s most famous gemstones have slight inclusions. To determine a diamond’s Clarity, an expert must examine the gem under 10X magnification. To help you select the diamond with a high quality, we only offer diamonds from Clarity grades Vvs to Si. Diamonds with FL and IF grades are available by special order.
The GIA has developed a clarity grading scale for diamonds as follows:
FL – Flawless: No inclusions or other types of blemishes under 10X magnification when observed by an expert.
IF – Internally Flawless: No inclusions observed under 10X magnification, might have minor blemishes.
Vvs1 & Vvs2 – Very Very slightly included: Contains minute inclusions barely visible to an expert under 10X magnification.
Vs1 & Vs2 – Very Slightly Included: Contains minute inclusions such as feathers, clouds or small mineral crystals barely visible under 10X magnification. Inclusions are not visible to the unaided eye.
Si1, Si2, Si3 – Slightly Included: Contains feathers, clouds, small mineral crystals or other imperfections that are noticeable to an experienced grader under 10X magnification. Si2 and Si3 grade (Si3 is a new classification that has been recently proposed) inclusions are not generally (but may be) visible to the unaided eye.
I1, I2, and I3 – Included: Contains inclusions such as large feathers or mineral crystals that are obvious under 10x magnification. Inclusions may be visible to the unaided eye and may affect transparency and brilliance.
The Key Point to Remember: The smaller and fewer the inclusions, the better.
