Diamond Education

So you want to know a little bit more about diamonds and what sort of diamond you should choose? Well you've come to the right place.

Here we'll go through the 4 C's of the diamond and get into what you should be looking for in each category. We'll also touch on shape and what the best settings are for each one. (Very handy when it comes to choosing a wedding band to match.)

Lets start with CUT....

A lot of people tend to get cut and shape confused and for good reason but cut refers simply to how deep or shallow the diamond has been cut. The diagram below shows the various grades of cut.

When looking at cut especially in a Round shape we tend to look for anything above a "good" simply because if a diamond is cut well it will let in the best amount of light - this is what causes the diamond to sparkle.

The next C is probably the most talked about C when it comes to diamond shopping and when looking at grades probably the C that effects the price the most.


Carat refers to the diamonds size. How big a diamond is can be measured in carats. To give you an idea and a scale the below image shows the various sizes and more importantly a scale to show realistically how big it is.

Strangely enough when looking at size you might hear some Jewellers talk about magic numbers. These numbers are the carat weight that seem to be the most popular for buyers and as such is reflected in price. For example the sought after 1ct. The 1ct is the most popular size for most buyers and we notice the price difference between a 1ct and a 0.98ct to be fairly significant. The difference in size is minuscule but because most people want the nice round number the price reflects the popularity.

So after you have decided on a size, more than likely you'll be looking at the next C.


Starting from completely colourless D and moving through all the way to yellow Z. We tend to group the colour grades to make it easier when explaining colourless, near colourless and so on.

The chart below shows the Colour Grades and Groups.


Keep in mind the bigger you go in terms of diamond size (Carat) the more expensive jumping colour grades gets...for example for a 1ct Round diamond the price for a F colour compared to a G may be in excess of $1000.00

The above diagram also shows the next and final C.


Clarity refers to the inclusions or natural marks in the diamond. Every single diamond is unique in this way. The clarity grade is very important when looking at diamonds. The SI range is a good place to start and usually SI1 inclusions are hard to see with the naked eye. Its when we start to get into the I1-I3 range that diamonds appear marked with black spots and clouds.

In turn the difference between a VVS and a VS grade is usually unrecognizable unless you have a magnifying loop and a trained eye.

Below is a diagram regarding shape...

By far the most popular shape for buyers is the Round Brilliant, however recently many celebrities have been seen sporting other shapes in unique settings.

It's very important to get the right advice on settings for different shapes. The last thing anyone wants is a diamond to come loose because it was not in the appropriate setting. Below are some settings for center stones and bands to show you the different options.
