Whether youāre shopping for an engagement ring, wedding bands, or a simple anniversary gift, knowing how to pick the right diamond is crucial. After all, you wouldnāt want to spend a large sum of money on a diamond only to realise that you splurged on a low-quality gem.
Thus, to avoid such an unfortunate event, weāll be diving into detail the foundations of basic diamond education: the 4C diamond-grading rubric. These are the four fundamental components of a diamondās structure that make up its quality.
The 4Cs

Up until the 20th century, there wasnāt an agreed-upon standard by which diamonds could be assessed. On top of the mysteriously-shrouded nature of the diamond procurement process, the lack of transparency made it almost impossible for consumers to gain accessibility and insight into the gem they were about to buy.
That all changed when the Gemological Institute of America (GIA) introduced the globally-accepted standards for describing and accessing diamonds: Cut, Colour, Clarity, and Carat Weight. Now, there is a universal language by which one can describe the quality of a diamond, a language that diamond customers have access to for make informed purchases.
A diamondās cut
When one thinks about a diamondās cut, one would naturally imagine its shape (round, oval, pear, marquise, and heart). While this isnāt technically wrong, what the diamond cut actually refers to is how the diamondās facets interact with light to produce its brightness, fire, and scintillation.
Diamonds are generally graded from excellent to poor, and each grade represents how well the proportions of its facets influence the diamondās face-up appearance. Naturally, a diamond with an excellent cut will require accurate design and craftsmanship to produce the high-grade sparkle. One that scores low in the cut grade will look dull and dim in comparison.
With that said, remember to take the diamondās pavilion depth into consideration. A diamond with a pavilion depth thatās too deep or too shallow may allow light to leak from its side or the bottom. A well-cut diamond will instead, direct more light towards the crown, thus giving you the concentrated bling that you desire.
A diamondās colour
When one looks out for a diamond with a high colour grade, one is actually opting for a diamond that has little-to-no colour! A structurally-perfect and chemically-pure diamond, in fact, has no hue whatsoever.
The GIA diamond colour-grading system measures the degree of colourlessness from D to Z ā with D being colourless and Z being a diamond that has a slight colour interference. In most cases, an untrained eye wouldnāt know the difference between two adjacent colour grades. Thus, you may want to consider consulting with an expert jeweller before jumping the gun.
A diamondās clarity
Many often make the mistake of equating a diamondās colour with clarity, and often refer to these two attributes interchangeably. However, theyāre not the same!
A diamondās clarity refers to the existence of blemishes and inclusion within the gem. These blemishes and inclusions come about when carbon is exposed to high heat and pressure. Since no diamond can escape from these imperfections, the closer it is from appearing pure and unblemished, the higher its value. After all, these imperfections can significantly affect a diamondās brilliance and sparkle.
The GIA grades clarity on a scale of ten from FL (Flawless) to I3 (Inclusions 3). Unlike a diamondās colour, distinguishing and identifying a diamondās clarity is slightly more straightforward and an I3 diamond appears dull due to the apparent inclusions and blemishes.
A diamondās carat
If thereās one thing thatās well known among informed and uninformed diamond consumers alike, it is a diamondās carat weight. The carat weight merely refers to its apparent size. Though it may be tempting to simply judge the overall attractiveness and quality of a diamond based on its size, letās not forget that a big size doesnāt guarantee a high grade of brilliance, fire, and scintillation. Itās best to consider the other attributes, lest you opt for a big carat diamond thatās also, unfortunately, dull and dim. Trust us when we say that a small but brilliant wedding diamond ring is all you need to attract the attention of many during your wedding reception!

Knowing the 4C diamond-grading rubric will be a tremendous help when youāre purchasing a diamond for yourself or a loved one. Not only will you be exposed to the quality of a diamond, but you will be able to narrow down the options to a diamond that is befitting of your budget. At the end of it all, do remember to have your diamond insured and ask for a diamond certificate from your jewellers!
