The world of diamonds is governed by “the four Cs.”
There’s color, which actually refers to the lack of color a stone has. One with no color is considered top quality, while a “brown” or “yellow” diamond is a lower standard diamond.
There’s carat, which is the weight of the diamond, and clarity, which refers to the presence or absence of inclusions – or flaws – in the stone.
And finally there’s cut, or the craftsmanship of a diamond: how the facets cooperate with light, the diamond’s overall finish and its proportions and symmetry.
