Grading Scale

FL-IF

Flawless, internally flawless. No flaws internally or externally. Extremely rare and beautiful diamonds.

VVS1-VVS2

Very, very slightly included. Very hard to see inclusions under 10X magnification. Diamonds of excellent quality.

VS1-VS2

Very slightly included. Inclusions usually not visible to the naked eye. Cheaper than VVS1 or VVS2 grade loose diamonds.

SI1-SI2

Slightly included. Inclusions visible under 10X magnification and might be visible with the naked eye. Good value.

SI3-I1

Included inclusions maybe visible without magnification, but an excellent choice for earrings. An SI3-I1 grade can be an excellent value, particularly since the inclusions are hard to see.

I2-I3

Inclusions can be seen without magnification and obvious under 10X magnification. May affect transparency and brilliance.
