Faint. Diamonds with a warm yellow colour that is visible to the unaided eye.
Faint. Diamonds with a warm yellow colour that is visible to the unaided eye.
The last near colourless grade. Diamonds with slight colour that can be detected upon close examination.
Near colourless. Good value diamonds with slight colour that can be detected upon close examination.
Near colourless. Exceptional value diamonds that only have noticeable colour when compared to much higher colour grades.
Highest near colourless grade. Exceptional value diamonds that only have noticeable colour when compared to much higher colour grades.
Colourless. High quality diamonds with miniscule traces of colour that can only be detected by a gemologist.
Colourless. High quality diamonds with miniscule traces of colour that can only be detected by a gemologist.
Completely colourless or icy white. Highest possible colour grade and also the most expensive.

Diamonds are graded on their lack of colour. The more colourless a diamond is the higher the quality.

Clarity

Slightly included 2. Inclusions can be seen under 10x magnification and may be visible to the unaided eye. Slightly more inclusions than SI1.
Slightly included 1. Inclusions can be seen under 10x magnification but may not be very visible to the unaided eye.
Very slightly included 2. Inclusions are difficult to see under 10x magnification. Slightly more inclusions than VS1.
Very slightly included 1. Inclusions are difficult to see under 10x magnification.
Very, very slightly included 2. Inclusions are very difficult to see even under 10x magnification. Slightly more inclusions than VVS1.
Very, very slightly included 1. Inclusions are very difficult to see even under 10x magnification.
Internally flawless. Rare and beautiful diamonds with no internal flaws.

The clarity of a diamond refers to the absence of inclusions which are impurities on and within the stone.

Depth

The height of a diamond, from the culet to the table. Depth % is the ratio of the height in relation to the girdle diameter

Gridle

Extremely Thin: May be prone to chipping or breaking; care should be taken when setting stone

Very Thin: Very Good gemstone proportion; care should be taken when setting stone

Thin, Medium: Ideal gemstone proportion

Slightly Thick, Thick: Excellent to ideal gemstone proportion

Very Thick: Good gemstone proportion

Extremely Thick: May make diamond look smaller, as more depth is taken up by gridle

Table

Culet

The tiny facet at the bottom tip of a gemstone. The optimal culet should be pointed or very small (graded "small" or "none").
