Diamonds - we all know that they are a girl's best friend and that they can be tremendously expensive, but for many of us that is the extent of our knowledge when it comes to diamonds.

Never fear, however, as there isn't too much that you need to know to be able to feel comfortable when looking at diamonds and, more importantly, make an informed purchase (which is quite important as you will most likely be wearing this diamond ring for the rest of your life!).

Right, let's begin. Essentially, to determine whether you the quality of a diamond, you need to look at the 4 C's: Carat, Cut, Clarity and Colour.


When someone tells you that a diamond is 0.75 carat, they are essentially telling you what the weight of the diamond is. Each carat is split into 100 points, so a 75 point diamond is 0.75 carat.

When comparing diamonds of the same quality, the larger that a diamond is, the more expensive it wil be. For example, a 2 carat diamond will be more expensive that two 1 carat diamonds of the same quality.

When choosing the size that you want, it may not always be best to go for the biggest that you can afford. There are two main reasons for this: first, a large diamond may not suit the size of your fingers and, secondly, a large diamond of low quality will most likely not look as good as a smaller, better quality diamond.

So how do you determine the quality, I hear you ask. For that, we look at the other 3 C's.


The cut of the diamond refers to how the diamond is physically cut. The quality of the cut will determine the brilliance of the diamond (how much the diamond sparkles) - the best diamonds are cut so that the light that goes into the diamond is refracted back outside the top of the diamond, making it sparkle.

When a jeweller cuts a diamond, they will choose whether to maximise the brilliance of the diamond or the size of the diamond (or compromise in the middle), as cutting the diamond to maximise its sparkliness is likely to mean that it will end up being a bit smaller.


How do you tell if a diamond is cut well? The best way is to compare a few diamond rings side by side and see what you like. There are no hard and fast rules in this regard and the ring setting may also affect how the diamond looks..


Diamonds can also be cut into a variety of shapes, the most common of which are the following.




It is all up to personal preference as to which cut you prefer, although some cuts look better on particular types of fingers.


The clarity of the diamond refers to how many "inclusions" a diamond has. An inclusion is a natural identifying characteristic that is particular to that diamond - it may look like a tiny crystal or cloudiness in the diamond.

They are often only visible when looking through a jeweller's magnifying glass.

The number, size and location of the inclusions within a diamond will determine its clarity. Flawless diamonds (with no inclusions) are very rare and are very expensive. The clarity of a diamond is rated on the following scale (with the best being VVS1):


VVS1 Very, very slightly included
VVS2 Very, very small inclusions
VS1 Very slightly included
VS2 Very small inclusions
SI1 Slighly included
SI2 Small inclusions
I1 Inclusions
I2 Noticeable inclusions
I3 Very noticeable inclusions


The clarity of the diamond that you are happy with will depend on your preference. Some people are happy to have a slightly bigger diamond that has some inclusions (which will not be noticeable to most people). Others, however, prefer to have a smaller, higher quality diamond.


Diamonds come in a range of colours, from colourless to a light yellow or brown. A colourless diamond is said to be better quality as it allows light to pass through the diamond better, resulting in a more sparkly diamond. The flip-side however is that colourless diamonds tend to be very expensive.

The colour of a diamond is rated on a scale beginning at D and continuing through the alphabet. To determine what colour of diamond you are happy with, the best thing to do is compare a few diamonds side by side and see which one you like best.


Choosing a diamond can be tremendously exciting - however, avoid disappointment by buying only from a reputable jeweller. They will be able to tell you all about the diamond - the cut, size, clarity and colour.

Remember though, the diamond that you choose does not have to be the biggest or the best. Almost all of us have a limited budget to stick to and will have to compromise on one or more of the 4 Cs, whether it means getting a slighlty smaller diamond or one that does not have as greater clarity or as purer colour. However, provided that you are happy with the diamond that you choose, not only will the diamond sparkle, but so will you!
