The more colorless a diamond is, the more it shines and the more intense the color analysis inside it is.

Colorlessness increases gradually, from slightly colored diamonds (Z) to completely colorless ones (D).

D/E/F = colorless diamonds

G/H/I/J = almost colorless diamonds

K/L/M = diamonds with a subtle color hue

N/O/P/Q/R = diamonds with a very light color hue

S/T/U/V/W/X/Y/Z = diamonds with a light color hue

They are a unit of measurement for the weight of the diamond.

One carat is equal to 0.2 grams.

The clarity of the diamond indicates whether it has any flaws (inclusions or blemishes in the stone).

The clarity grades are as follows (in descending order):

1. Loupe Clean (LC): Completely clean diamonds

2. Flawless (FL): No visible flaws

3. Internal Flawless (IF): No inclusions, but slight external blemishes

4. Very very slightly included (VVS1/VVS2): Diamonds with very small inclusions that are very difficult to see under magnification

5. Very slightly included (VS1/VS2): Diamonds with very small inclusions that are difficult to see under magnification

6. Slightly included (Si1/Si2): Diamonds with small inclusions that are easily visible under magnification

7. Pique or Included (Pi1/Pi2/Pi3 or I1/I2/I3): Diamonds with inclusions that are visible to the naked eye
