Diamond Characteristics... The Four C's of a Diamond.

 
Cut.

A diamond cut to proper proportion allows the greatest amount of light to be reflected, which gives you maximum brilliance. It's cut, polish, proportions and symmetry, are of utmost importance since these factors determine the life, brilliance and dispersion of the diamond. If these cutting factors fall below standard, the appearance of the diamond will be adversely affected.

Colour.

Most diamonds of gem quality vary in shade from colourless to yellow.

To determine the correct colour, all submitted diamonds are compared to an internationally accepted master set of stones. Colour ranges from D, or colourless (the most sought after) to Z, the yellowest.

Diamond Colour

Other colours occur in diamonds such as brown, orange, pink, blue, etc. The most intense of these shades are determined as "fancy" colours.
 


Clarity.

Imperfections in a diamond are like fingerprints - no two are alike. The fewer imperfections in a diamond the better. All "Eternal Diamond" diamonds are SI2 or better. In order to grade the clarity of a diamond, it is necessary to observe the number and nature of any internal characteristics in the stone as well as their size and position.

This analysis is carried out using the scope and a loupe 10x under the experienced eye of laboratory gemologists. A diamond is said to be 'internally flawless' when it presents no internal defects under 10x magnification.

Carat Weight.

The weight or size of a diamond is measured in carats (ct.). A carat is 0.2 grams and there are 100 points (or 200 milligrams) per carat, with an accuracy of 1/100,000ct. Scales provide a highly precise diamond weight and this weight is specified on the Diamond Report.
