What Is The Most Expensive Diamond Cut - 2022-10-17

What Is The Most Expensive Diamond Cut

The four Cs of diamonds - carat, cut, colour and clarity - are all central factors contributing to the overall value of the diamond. However, one particular aspect that determines the price of your engagement ring is the cut! In this blog we will teach everything you need to know about the most expensive diamond cut and what makes it so valuable.

Why Is the Cut of a Diamond So Important?

The importance of diamond cutting cannot be overstated. Cut correctly, and you will see more sparkle from your diamond than ever before! Before these gems go through their initial faceting process to create that captivating beauty in jewels, the cutting process ensures that the light will bounce off of them and sparkle into the eye.

What Are the Diamond Cut Grades? Each diamond is assigned one of the four cut grades by the Gemological Institute of America (GIA). The grades affect not only how they look but also how light reflects through them. 

Below are the types of cutting grades:


These diamonds are the best of their kind. They shine with flawless brilliance, making this an excellent cut diamond for you or someone special in your life. They are rare (about 3% of all diamonds in the world) and well crafted, allowing little to no leakage of light passing through them. 

Very Good

As an experienced diamond merchant, this grade is almost perfect for the following reasons. 

They have minimal light leakage with brilliant color rendering.

If budget restrictions prevent you from spending more on excellent quality, then this grade will suffice for anyone looking to prioritize something other than brilliance, such as carat weight.

The key takeaway here is you get what you are promised, a brilliant yet more affordable gemstone!

Good What is better than a diamond? A sparkling, light-reflecting diamond! The higher the grade, the more brilliant and sparkly it will be. Good cut stones have some leakage but still shine bright with all their beauty - which is why they make such great gifts for any classy jewellery lover.

Fair and Poor

These diamonds let light leak from their depths, making them less than ideal for jewellery. They have little to no brilliance, meaning that your pieces will not sparkle or shine as much compared to other grades of diamond in the same price range.

Now let us get to the bottom line of the most expensive diamond cut.

The Most Expensive Diamond Cut: The Round Brilliant Cut

From the name, you can already tell it all.

The Round Brilliant stone has a perfect fifty-seven faceted surface, with its brilliance shining through. The key to this cut is total internal reflection; light can travel straight through without being refracted by any of the other angles in between each piece, making for optimum sparkle and scintillation qualities.

The most popular gemstone on Earth right now? You guessed it right!

Benefits of the Round Brilliant cut


The brilliant-cut diamond is a versatile and popular shape that will suit the needs of many different people. You can find an engagement ring with this type alongside color options like rose or yellow gold to add more flair depending on your style.

No Sharp Edges

It does not matter what kind of diamond cut you choose because the brilliant round is secure and durable. It will not chip or break from a hard surface.

Setting Options

You don't need to worry about which setting you want for your brilliant round gemstone. You can get a prong, bezel, or tension setting.

Resale Value

If you're ever looking to upgrade your ring, there is no need for concern. The resale value will not decrease because of trends or less demand from potential buyers interested in the type and style of jewellery like yours.

What Makes A Diamond Sparkle - 2022-10-17

What Makes A Diamond Sparkle

Diamonds are famous for their distinctive glitter and glow, but what really makes a diamond sparkle?

The short answer is the diamond's cut. It is therefore important to understand what a diamond's cut is, and how the sparkle is created.

What Are The 4C's Of A Diamond?

The Gemological Institute of America (GIA) came up with a broadly acceptable industry standard for evaluating the quality of diamonds. Consequently, diamonds are evaluated based on these certain set of parameters called the 4C's. The components of the 4C's are:

  • Colour
  • Clarity
  • Cut
  • Carat weight

So, as you can see, Cut is a component of the evaluation matrix of diamonds. Yet, according to GIA, Cut is the most important indicator and predictor of a diamond's worth and value.

So, what exactly is a diamond cut?

What Is A Diamond Cut?

Contrary to what you may think, a diamond's cut has almost nothing to do with the shape and form of a diamond. Instead, a diamond's cut is a measure of how the diamond's facets interact with light. The diamond's facet is the flat, even exterior on a gemstone.

You can think of a diamond's facet as a diamond's face. A typical diamond has about 58 facets, or mirror-like faces.

So, how exactly does it work?

How Does A Diamond's Cut Affect It’s Sparkle?

We've seen that a diamond's cut is all about the symmetry and evenness of its facets. It's these facets which—depending on how well polished and symmetrical they are— absorb, reflect, or refract light in a way that will make diamonds sparkle.

The way light will behave after hitting the facet is what will determine how sparkly the diamond will be. And in short, the behavior of light is determined by the quality (and workmanship) of the facet. This quality and workmanship of a facet is what is referred to as a cut.

That's how a diamond's cut influences the degree to which a diamond will sparkle!
