Diamonds are one of the world’s most prized treasures - but they don’t come out of the Earth looking like a million bucks! In fact, they look like… well, rocks. The appearance is dull, and it is in the hands of cutters that the true beauty is revealed. 

Diamond cutting has been in practice since at least the 14th century, and before that, they were polished to enhance some of the shine. In the 11th century, the stones were revered as “magical” objects. In the centuries since, techniques have evolved, as has the skill of expert cutters. A large brilliant cut diamond is, in many ways, the culmination of this mastery.

Brilliant Cut Diamond Definition 

Many of us still regard diamonds as magical objects! They are simply stunning, and brilliant cuts are designed to maximize the appeal of the stone: the shine, the sparkle, the elegance. We can see the evolution of cutting here too. 

In comparison to diamonds from different periods having very distant appearances and differences. As techniques became more refined, these advances ensured maximum brilliance, fire, and scintillation.

The cut of a brilliant is not accidental; in fact, it is borne of centuries of practice, as well as the integration of new techniques and technology. For example, in 1919, Marcel Tolkowsky, a Belgian gemologist, and mathematician figured out the best way to design and cut a diamond; he believed that the stone is a system of mirrors and windows. With perfect symmetry and proportion, you can capture as much light as possible.

As we talk about the brilliant cut diamond definition, it is also important to become familiar with these terms:

  • Brilliance: white light reflected from the facets
  • Fire: reflected color created when white light is dispersed through the diamond
  • Scintillation: the sparkle we see when the reflections interact as the stone is in motion

Tolkowsky’s developed scientific calculations when it came to cutting and polishing diamonds to maximize these attributes. 

A brilliant cut diamond has 58 facets (including the culet). The crown (i.e. the upper portion of the stone) has 33, while the pavilion (i.e. the lower portion of the stone) has 25. But it’s more involved than that: the crown has one table facet, eight bezel facets, eight star facets, and 16 upper girdle facets, while the pavilion has eight facets, as well as 16 lower girdle facets and a culet. Cutters must ensure that these facets are perfect in terms of symmetry and proportion.

Speaking of which: the table, crown, and pavilion all must be in proportion to each other. For instance, if the table is too large, then too much light can escape. This will give it a duller appearance than it should have. If the pavilion is too deep or too shallow, light is lost through the bottom, and we miss out on the brilliance we crave. 

Tolkowsky played a large role in the development of the modern brilliant cut; today’s technology, including laser cutting equipment, which ensures the utmost precision. This is crucial in achieving the level of symmetry and proportion that defines a brilliant cut diamond.

Why Invest In a Large Brilliant Cut Diamond?

As a professional in the jewelry industry, it is essential that you deliver the quality and aesthetic that customers want. It is also critical that you maximize your margins. A large brilliant cut diamond can be the route to both. Round brilliants are the most popular stones on the market, accounting for more than 70 percent of sales. 

The reason for this is obvious: They are iconic! When people picture the ideal engagement ring, for instance, it’s most likely that a brilliant cut diamond will pop into their mind. This cut also delivers unmatched brilliance, fire, and scintillation. The beauty and glamor of the brilliant are undeniable.

You will see a higher price point when it comes to purchasing a large brilliant cut diamond. The cutting process is labor-intensive, and it must be meticulous and exacting. Even in the hands of a master, there is a good deal of waste involved in cutting. You may, for example, lose up to 60 percent of the carat weight as a rough diamond is transformed into a customer-ready brilliant cut stone. 

However, many customers accept a higher price point in return for the quality and enduring beauty they receive.
