4C of Diamond
4Cs” is the grading standard of a diamond,
representing carat (weight), color (color grading),
clarity (characteristics) and cut (polish and symmetry).
The higher the grading of 4Cs is rated,
the more precious and brilliance the diamond will be.
- Carat
- Color
- Clarity
- Cut
I-PRIMO only uses the highest graded, “Excellent” cut diamonds.
Cut is the only human factor in the 4Cs
that affects the brilliancy and sparkle of a diamond.
In general, colorless diamonds are the rarest and also more valuable.
Apart from pink, blue or other fancy-colored diamonds, colorless diamonds are the most expensive.
The highest color grade is “D” (the first letter of the word “Diamond”).
As the depth of color increases, the grading will be lower.
It is the basic grading of the pureness of a diamond.
Clarity means the pureness of a diamond.
The clarity of a diamond is rated by the size, location and quantity of inclusions and blemishes,
that are seen under 10X magnification based on a grading system with eleven clarity grades.
I-PRIMO only uses the highest graded, “Excellent” cut diamonds.
Cut is the only human factor in the 4Cs
that affects the brilliancy and sparkle of a diamond.
