The 4 C's
Diamonds are classified according to various parameters, the combination of which determines their value.
Cut
The cut of a diamond is one of the most crucial aspects that determine the beauty and value of this precious gem.
A well-executed cut not only enhances the visual appearance of the diamond, but also maximizes its brilliance and sparkle.
The grades for evaluating proportions, symmetry and polish (polish) are as follows:
“Excellent”, “Very Good”, “Good”, “Fair” and “Poor”.


Carat -Weight
Carat is the unit of measurement of diamond weight and is one of the four fundamental characteristics that determine the value of a diamond, along with Cut, Color and Clarity.
One carat is equal to 200 milligrams (0.2 grams) and is divided into hundredths commonly called "points"; for example, a stone weighing 0.50 ct may also be said to weigh "fifty points" or one weighing 1.09 ct may also be said to weigh "one carat and nine points".

Clarity
During its formation, diamond is subjected to incredible pressures and temperatures.
Precisely because of these factors, it is easy to find small inclusions and small fractures inside it.
The presence or absence of these “inclusions” determines the purity of the diamond.
For this purpose, an international scale is used where IF represents the best purity (pure at 10x magnification).
IF Internally pure, VVS1 – VVS2 Very small inclusions very difficult to see, VS1 – VS2 Very small inclusions difficult to see, SI1 - SI2 Small inclusions easily visible, I1 – I2 – I3 Inclusions visible to the naked eye






Color
Diamonds exist in nature in various colors. The most common, objects of trade and investment, are
They range from colorless to yellow. Their color is evaluated in degrees according to the GIA scale, currently the reference scale worldwide. The degrees are expressed by letters of the alphabet starting from D to Z. On the scale, D represents the best color (colorless).
