A guide to the Four C's
Choosing your diamond is an exciting process and can be steep learning curve. The price of a stone is affected not just by size, but by many other variables. The Four C's (carat, cut, clarity, and colour) all affect a diamond's value. For example, a large diamond may be less expensive than one that is smaller but has better colour or clarity. In short, there is no right or wrong answer when selecting your stone. However, familiarising yourself with the different grades and how they work can help you make the choice that's right for you.

Carat
The carat is the unit used to measure the weight of diamonds and other precious stones. One carat is equivalent to 200mg. It can be further divided into 100 "points". The price per carat varies according to the size of the diamond. For example, a 1ct diamond costs much more than double the amount of a 0.50ct diamond of the same quality. This is because larger diamonds are rarer, and can therefore be more valuable - depending, of course, on other variables such as cut and clarity.
Cut
The way a diamond is cut affects its fire. A well cut stone reflects rays of light internally from one facet to another, making it more brilliant. A diamond that is proportionately too deep or too shallow will lose light through its side and bottom facets, and sparkle less. The quality of a stone's polish and symmetry also affect its brilliance and its value. The best cut stones are graded "Triple Excellent", because of their excellent cut, polish and symmetry.
Clarity
Natural internal imperfections such as cracks and clouds occur often in diamonds, and are known as "inclusions". They are not always visible to the naked eye, but they can disrupt the refraction of light in the diamond, and affect its brilliance. Flawless diamonds are extremely rare, and therefore more valuable. The size and position of inclusions affect a diamond's value; the further they are away from the centre of the stone the better. The following table explains the various clarity grades:
| F | Flawless | No visible flaws |
| IF | Internally Flawless | No visible flaws using 10x magnification |
| VVS1 | Very Very Small Inclusion 1 | Very difficult to detect flaws using 10x magnification |
| VVS2 | Very Very Small Inclusion 2 | Very difficult to detect flaws using 10x magnification - flaws maybe slightly more central |
| VS1 | Very Small Inclusion 1 | Difficult to detect flaws under 10x magnification |
| VS2 | Very Small Inclusion 2 | Difficult to detect flaws under 10x magnification - flaws may be slightly more central |
| SI | Slightly Included | Flaws easily visible under 10x magnification |
| I1 | Included Diamond 1 | Flaws visible to the naked eye |
| I2 | Included Diamond 2 | Flaws visible to the naked eye (more severe) |
| I3 | Included Diamond 3 | Flaws visible to the naked eye (most severe) |
Colour
Diamonds are colour graded using the alphabet starting with the letter D for colourless, and then E, F, G, and so on, as the stone becomes more tinted with yellow. Whiter stones are generally the most sought after, with the exception of coloured or "fancy" diamonds, which have their own descriptions.
Other Considerations
Fluorescence
Natural fluorescence is caused by sub-microscopic structures within the diamond that cause it to glow when it is exposed to UV light. Blue is the most common fluorescence, but others colours such as yellow and green are also possible.
The GIA grades the strength of fluorescence as none, faint, medium, strong, or very strong. If a diamond has medium fluorescence or stronger, the colour of the fluorescence will be noted. Some jewellers believe that fluorescence is always an undesirable characteristic. However, GIA studies indicate that this is not necessarily so, as in some cases fluorescence can enhance the diamond's appearance.
Certification
What we commonly call diamond "certificates" are actually diamond grading reports. These reports are prepared by independent, certified gemmologists from laboratories around the world, and contain details of the specific characteristics of your diamond. Not all diamonds are sold with reports, and having one does not increase the value of your stone. It acts more as a consumer safeguard to confirm your diamond's authenticity and characteristics. If you buy an "uncertified" diamond, it is possible to have a grading report done subsequently.
Below is a guide to some well known organisations that provide grading reports:
| GIA | Gemmological Institute of America |
| HRD | Diamond High Council (Belgium) |
| BGI | British Gemmological Institute |
| IGI | International Gemmological Institute |
| AGS | American Gemmological Society |
| EGL | European Gemmological Laboratory |
