Diamonds

At Adam Foster, we built strong partnerships with trusted diamond vendors to provide our
clients with access to the finest diamonds at the best values.

Although every diamond is unique, all diamonds share certain features that allow for comparison and evaluation. These features are called the “4Cs”: Color, Clarity, Cut and Carat Weight.

The GIA developed the 4Cs, as well as the International Diamond Grading System. Every GIA grading report accompanying a diamond contains information

Cut

Color

Clarity

Clarity is determined by the visibility of natural microscopic inclusions and imperfections within a diamond.
