When choosing your diamond, be sure to always take the diamond’s cut heavily into account, as it is the main factor that decides whether your diamond is a beautiful living work of art, or if it is a dud. The cut of a diamond is by far the essential factor that maximises the diamond’s sparkle and its ability to radiate light and shimmer.
If you are to choose between a diamond’s cut, colour or carat, be sure to always prioritise the cut of the diamond. Having a big diamond is pointless if it looks dull and lifeless. On the other hand, a diamond with a perfect cut can radiate light so brilliantly that it seems bigger than it actually is!
To simplify your search effort, always go for GIA’s “Excellent” grading, or AGS’s Ideal (0) rating. Be sure to prioritise getting a diamond with a good cut, and do not be tempted by getting a heavier stone with an inferior cut.

What is a Diamond Cut?
[add some pretty perfect diamond here]
The cut of a diamond refers to the proportions and angles between the facets of a diamond. The more well-proportioned the cuts of a diamond is, the higher the quality of the diamond and the better it radiates light and shimmers. It also refers to how the many angles on the facets of the diamonds interact with one another, and effects how light reflects within the gemstone.The cut of a diamond heavily affects the amount of sparkle that radiates from the diamond, and also how beautiful it looks – thereby strongly affecting the final value of the diamond.
Anatomy of a Diamond
The figure shows the many parts of a diamond, as is known in the gemological industry. As you can see, there is a name for each specific part, and it can get confusing. However, fret not – you do not need to know these specific parts of a diamond. What matters the most is the ratio and proportions of each of these parts – it is better for you to make judgement with a holistic view of the diamond rather than breaking it down and wasting time fretting on the specifics.
What Makes a Diamond Sparkle?

There are three ways to describe the way a diamond sparkles, and while the perfect cut tries to maximise all three ways as much as it can, it pays for you to know these three ways as you may have a personal preference to how you want your perfect diamond to look.
Fire – this is how the diamond disperses coloured light; the rainbow of colours that reflect out of a diamond.
Brilliance – this is how the diamond reflects white light; the intensity of the light, making the diamond appear brighter.
Scintillation – this is how the diamond sparkles when light is moved, giving it its intense sparkle.
The Ideal Cut
There is a reason why round diamonds are usually portrayed in its stereotypical shape and proportions. This is because it represents the ideal cut of a diamond – a cut that allows a diamond to perfectly reflect light and intensify its beauty.
A shallow cut diamond is too flat. They may seem large because of their bigger table size, but the shallowness will cause the light to reflect on the pavilion at a low angle, and out the diamond through the sides and bottom. This causes the diamond to lose its brilliance since light is not reflected in an ideal manner.
A deep cut diamond is too narrow and tall. A deep diamond may be a byproduct of trying to remove blemishes, but cut in a way to preserve its carat weight. When a diamond is cut this way, the light will reflect on the pavilion at a sharp angle and escape through the opposite side of the diamond. Similar to a shallow cut diamond, a deep cut diamond loses its brilliance and fire since light is escaping from the sides and not reflected in an ideal manner.
An ideal cut diamond is cut in the perfect proportions that allows a diamond to exhibit its true potential. A diamond that is cut in an ideal way is one that allows light to reflect at its pavilions and reflect back out through its table, the top of the diamond. When looking at a diamond cut this way, you can truly see the brilliance and sparkle radiating from the gemstone.
Diamond Cut Grading
When it comes to diamond grading, two institutions stand out from the crowd, and is considered the industry standard when it comes to diamond and gemstone grading – GIA and AGS. These two are the most trusted in the industry.
Many people who are beginners in purchasing diamonds have been swindled or misled by other grading companies, as many could be in-house or have undisclosed financial interests. Furthermore, they may be less consistent or accurate than the two powerhouses. So to simplify your search, make sure you look at only GIA or AGS gradings.
GIA/AGS Grades Chart
These diamonds are of the highest quality and are cut in the most perfect way to maximise its brilliance. You cannot go wrong with diamonds of this grade.
Diamonds of these grade are still extremely high quality, and will allow most of the light to shine through it and reflect. Without magnification, diamonds of this grade are pretty much indistinguishable from diamonds of Excellent (GIA) or Ideal (AGS 0) quality.
Diamonds of this grade may not sparkle with as much brilliance as diamonds of higher grades, but they still look great, and can be a good choice if you are on a budget.
Diamonds of this cut quality offer very little brilliance, as light escapes through its sides and bottom. Not worth your money.
As the name implies, diamonds of this cut quality is of poor quality, and you should avoid at all costs.
GIA uses a grading system that ranges from Excellent to Poor, while AGS uses a grading system that ranges from Ideal to Poor. When in search of your perfect diamond, always go for diamonds graded “Excellent” by GIA, or “Ideal” by AGS. Even a drop in a single grade can have a huge difference when it comes to the brilliance, fire and scintillation of the diamond. Diamonds that have a cut grade of “Very Good” by GIA or “Excellent” by AGS are also a very good choice for your diamond, as they can be obtained at a lower cost than diamonds of the highest grade, and are almost indistinguishable to the naked eye. However, if you are shopping on a tight budget, you may want to consider a grade lower – “Good” by GIA or “Very Good” by AGS. They may not sparkle as brilliantly as the top of the line grades, but you can be sure to get the best bang for your buck – they are cuts of high quality, and still offer a great amount of brilliance and sparkle, especially considering the price point. However, avoid any grades lower than that as the quality quickly drops off a steep cliff from there, and the diamonds of these lower levels are dull and lifeless.
While all 4C’s – Cut, Clarity, Colour and Carat play a role in deciding the quality of a diamond, the Cut is by far the most important trait of any diamond. A perfect cut can make a diamond more brilliant and seem bigger than it actually is – which is, after all, the whole point of getting a diamond in the first place.
If your budget allows, be sure to only choose diamonds graded “Excellent” by GIA or “Ideal” by AGS. This will ensure that you get the best quality of diamonds. Do not compromise on cut! It is the difference between a diamond that captures the heart of an entire room or a dull stone that nobody looks at!
