HOW GIA GRADES
YOUR DIAMOND

Every diamond is unique, yet all diamonds share certain features that allow us to compare and evaluate them. These features are called the 4Cs: Color, Clarity, Cut and Carat Weight. The GIA developed the 4Cs and the International Diamond Grading System™, the standard used around the globe. Every GIA grading report accompanying a diamond contains these key assessments and more to help you buy with confidence.

COLOR

The GIA Color Scale extends from D (colorless) to Z (light yellow or brown). Although many people think of gem quality diamonds as colorless, truly colorless diamonds are actually very rare. Most diamonds used in jewelry are nearly colorless with tints of yellow or brown.

CLARITY

The GIA Clarity Scale spans eleven clarity grades ranging from Flawless to I3. These internal and external characteristics are a by-product of a diamond’s natural formation under intense heat and pressure and help gemologists separate natural diamonds from synthetics and simulants, and identify individual stones.

CUT

The GIA Cut Scale ranges from Excellent to Poor. A polished diamond’s magnificent display is made up of three attributes: brightness (white light reflecting from the surface and interior of a diamond), fire (the ‘flares’ of color emitted from a diamond), scintillation (the pattern of light and dark areas and the sparkle you see when the diamond, the light, or the observer moves).

CARAT WEIGHT

One carat equals 200 milligrams in weight. For diamonds under one carat, each carat is divided into 100 points-similar to pennies in a dollar.

0.75 ct. = 75 points

0.5 ct. = 50 points
