The 4C's

These characteristics do not only determine the stone’s quality, they can also be very useful in identifying the diamond, since every diamond is unique.

The quality of a diamond is defined by means of the C’s: Carat, Clarity, Colour and Cut.

Carat refers to the weight of a diamond.


Clarity                                            Learn more…

The clarity or purity of a diamond is determined by the number, size, brightness and location of the internal and external characteristics, important structure phenomena and transparency.


Colour                                             Learn more…
