GIA Diamonds

Every diamond is unique. Each reflects the story of its arduous journey from deep inside the earth to a cherished object of adornment. Yet all diamonds share certain features that allow us to compare and evaluate them.

These features are called the 4Cs.

The 4Cs of diamond grading helps you understand exactly what you are buying. That’s why GIA created this universal standard for diamond quality. And why we proudly offer diamonds graded by GIA.

4C’s OF DIAMOND QUALITY Download

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. Color grades are determined by comparing each diamond to a master set. Each letter grade represents a range of color and is a measure of how noticeable a color is.

Fluorescence

Some diamonds can emit a visible light when exposed to ultraviolet radiation, but fluorescence is not a factor in determining color or clarity grades. However, a description of its strength and color is provided on GIA Reports as an additional identifying characteristic.

Clarity

The GIA Clarity Scale includes eleven clarity grades ranging from Flawless to I3.

Because diamonds form under tremendous heat and pressure, it is extremely rare to find a diamond that lacks any internal and external characteristics. These characteristics are a by-product of its formation and help gemologists separate natural diamonds from synthetics and simulants, and identify individual stones.

Cut

The GIA Cut Scale ranges from Excellent to Poor.

Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of diamond’s cut as a shape (round, emerald, pear), but a diamond’s cut grade is really about how well a diamond’s facets interact with light.

A polished diamond’s beauty lies in its complex relationship with light. The magnificent display you see is made up of three attributes:

  • Brightness is the combination of all white light reflecting from the surface and interior of a diamond.

  • Fire describes the “flares” of color emitted from a diamond.

  • Scintillation describes the pattern of light and dark areas and the sparkle you see when the diamond, the light, or the observer moves. A diamond’s proportions affect its light performance, which in turn affects its beauty and overall appeal. Diamonds with fine proportions, symmetry, and polish optimize their interaction with light, and have increased brightness, fire, and scintillation.

Carat

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, 1/2 ct. = 50 points.
