Diamond Quality: The 4 Cs
When looking at the quality of a diamond, you have to consider four different characteristics of the stone – Cut, Colour, Clarity and Carat Weight. These make up the four Cs that are the most important factors you should look at when shopping around for a diamond.
The cut of a diamond is essentially the characteristic that determines its sparkle, professionally known in the industry as brilliance. Out of the 4 Cs, the cut is the biggest influencing factor behind the diamond’s appearance. Even with perfect colour and clarity, a poor or even fair cut can make the diamond look dull and lifeless. At Diamond Exchange, you can shop at ease knowing that we only carry diamonds of Ideal, Excellent, Very Good and Good cut grades, which make up the top grades for the cut of a diamond.

When talking about the colour of a diamond, an easy rule to remember is that a colourless one is more highly valued than one with visible colour. To put it simply, white diamonds that contain little to no colour are of higher grades than those that have noticeable colour. At Diamond Exchange, we only carry diamonds with colour grades between D to J, which are the highest in the colour grading system.

The formation of diamonds happens in the earth, over millions of years and under extreme heat and pressure. Because of such conditions, each diamond comes with natural marks or imperfections within it, and these marks are better known as inclusions. This natural process ensures that no two diamonds have the same inclusions, so the clarity of a diamond is what makes each one truly unique. The general rule of thumb is that the fewer inclusions a diamond has, the rarer and more highly-valued it is.

A carat is the standard measurement of a diamond’s weight. As explained under Cut, exact proportions have been calculated so a diamond can be cut to reflect the maximum amount of light through the top of the stone. These exact measurements mean that the weight of a well-cut diamond is proportionate to the millimetre width of a diamond. So although carat has been used as a term of measurement for weight, it is also an indication of the size of the diamond. And since large diamonds are much rarer than small ones, the value of a diamond rises in proportion to its carat weight.

As the name suggests, the shape refers to the form that the diamond takes, when viewed from the crown (top of diamond). There are many shapes in which diamonds are cut, and each has its own unique features. As the choice of shapes would greatly depend on personal taste, we recommend that you check out all available shapes first to see which you prefer.
Most diamond engagement rings on the market today are set with a round diamond, though a square princess cut diamond engagement ring has been an up-and-coming popular trend as well.

The first thing you should know about the size of a diamond is that it is proportionate to its weight. As you begin viewing diamond rings both in-store and online, you will see that there is a wide range of diamond sizes catering to your budget. However please note that no matter the size of the diamond, it is the quality of the stone that truly matters.
The above is a simple chart to give you an idea of the diamond size that would best suit your budget. For more information on the different diamond sizes we have available in Diamond Exchange, download our Diamond Carat Size Chart <link to I022 Diamond Carat Size Chart PDF> now.
Once you have decided on the stone and are just about to hand over your credit card, Diamond Exchange highly recommends that you ask to view a copy of the diamond’s certificate. The accompanying papers, created by a team of gemmologists, serve as proof that the diamond has been independently and professionally examined and certified, so you can purchase your diamond with absolute confidence.
At Diamond Exchange, we only offer diamonds that have been individually assessed by the renowned Gemological Institute of America (GIA). For more information, head over to read about Diamond Exchange’s Diamond Certificates.
