CUT

The cut is a combination of Shape and Proportions. The shape describes the general outline of the stone, for example round brilliant, princess cut, pear shape, oval etc. Good proportions give better light reflection in the diamond and thus contribute to its beauty.

CLARITY

Almost every diamond has a unique nature fingerprint. These fingerprints are called inclusions. The clarity grade reflects how “pure” the stone is.

The clearer the diamond, the greater its brilliance, and the greater its value. Most diamonds have natural inclusions. These can be tiny traces of carbon (black spots), air pockets (white spots) or other naturally occurring phenomena. Diamond clarity ranges from extremely rare diamonds without any flaws (internally flawless) to those that have visible inclusions.

COLOR

The diamond color grade measures how colorless a diamond is. This scale refers only to colorless (white) diamonds, and not fancy colored gems. The color scale goes from D to Z (no diamond of color A, B or C has ever been found), with D being the most white and Z being the most yellow. The most valuable diamonds are colorless.

Colorless diamonds allow most light to pass through the stone and create the most brilliance. However, very few diamonds are colorless, so most diamonds will have a tint of yellow – the less yellow the better.

CERTIFICATE

A diamond Certificate from DGLI means your diamond has been subjected to highly scientific evaluation by a distinguished team of gemologists using State-of-the-Art instrumentation to assure you the most accurate assessment of the diamond you are buying.

Official DGLI certificates include a letter-sized certificate with a detailed diamond report.

A standard DGLI certificate includes the following parameters: DGLI unique certificate number, certificate issue date, diamond weight in carats, shape and cut, diamond mm measurements, diamond proportions (depth, table width, crown height, girdle thickness), diamond finish grading (polish, symmetry, culet), clarity grading, color grading, fluorescence.
