Diamonds are forever... but they aren't all the same. Here's how to tell your diamonds apart.

Ensuring you understand the fundamentals of diamond quality will not only help you determine whether your diamond is the quality you desire - but also that you’re not paying more than you should be. To the untrained eye, it’s often near to impossible to tell the difference between two closely graded diamonds - however it can make a vast difference to the price. Firstly, it’s imperative to recognise the importance of the 4Cs. These are the main 4 qualities that determine the worth and rarity of your diamond. 

The 4Cs: Cut, Colour, Clarity and Carat


Firstly, we’ll take a look at the ‘cut’ of the diamond. This can have a vast effect on the price and quality of your diamond. The most popular (and expensive) diamond-cut available is the round brilliant. And it isn’t expensive just because it is in the most demand. The term ‘brilliant’ comes from the results of carefully cutting and shaping 58 facets onto the surface of the gem. This excruciating attention to detail lends itself to reflecting a brilliantly white light, which in turn gives the gem a fantastic radiance.


Colour also changes the price and quality of diamond, to varying degrees. For example, a ‘white’ diamond with a slightly yellow cadence will likely be worth significantly less than a diamond imbued by refraction with a deep yellow glow. Typically, diamonds are white gemstones, however when a defect causes the colouration to become a deep, rich colour - these diamonds become exceedingly desirable.


The clarity of the diamond is yet another imperative quality indicator. It is extremely hard to notice any defects with the diamond to an untrained eye, and so a trained diamond grader must check the stone. The clarity rating of a diamond refers to the number of inclusions (visible defects in the inside of the gemstone) or blemishes (spots on the diamond’s surface) that affect the diamond’s ability to refract light. A flawless diamond is the most desired and high quality stone available. This has no inclusions or blemishes visible under a 10x magnification.


The ‘carat’ is usually the one people think about first when you consider the quality of a diamond. Contrary to popular belief, the carat doesn’t actually refer to the size of a diamond - but the weight. Each carat is subdivided into 100 points. This allows for extremely precise, and accurate measurements, to the 100th decimal place. Of course, the higher the weight - and thus the higher ‘carat’ - the more expensive the diamond will be.
