DIAMONDS - THE 4 C's DIAMONDS - THE 4 C's
Diamonds are weighed in metric carats. For reference, a small paper clip weighs about two carats.

Clarity

Diamonds are created by nature under tremendous heat and pressure. Nearly all diamonds contain unique internal characteristics called inclusions and external characteristics called blemishes. Many clarity characteristics are too tiny to be seen by anyone other than a trained gemologist using magnification. The GIA Clarity Scale contains 11 grades ranging from Flawless to Included.

Color

Truly colorless diamonds are very rare and highly valued. The GIA Color Scale uses letters to represent the absence of color, beginning with D (colorless) and ending at Z (light yellow or brown). Color distinctions can be quite subtle and only visible to the trained eye, but the differences can have a significant impact on price.

Cut

While diamonds can be fashioned into different shapes, the term ďcutĒ refers to how a diamondís complex proportions and angles relate to light. A number of factors influence a diamondís cut grade, including its overall face-up appearance, design and craftsmanship. The GIA Cut Scale for standard round brilliant cut diamonds ranges from Excellent to Poor.

ASK FOR AN INDEPENDENT DIAMOND GRADING REPORT

A diamond grading report is an unbiased assessment of the diamondís quality. It provides a description of the diamondís 4Cs and confirms that the stone is a natural or synthetic diamond. The report also discloses any treatments the diamond may have undergone to alter its color or clarity. You can verify the information contained in any GIA report by entering the report number in Report Check, GIAís secure online database.

KEEP YOUR PURCHASE SECURE

A laser inscription will help identify your diamond if itís ever lost or stolen. You can request to have the diamondís report number or a personal message inscribed on the girdle (the diamondís perimeter). The inscription is viewable using a jewelerís loupe or microscope under 10X magnification. Diamonds that come with GIA Diamond Dossierģ reports contain the diamondís report number laser inscribed on the girdle.
