What Is The Most Expensive Diamond Cut?
Do you want to know what the best diamond cut is? What about the most expensive one? Diamonds have enchanted buyers for millennia with their elegant elongated shapes and brilliant square patterns. However, whether a mined stone or a lab-grown diamond, there is one thing that we all know about these prized stones: they can be quite expensive.  So, which diamond cut is the most expensive? Read along if you are curious.

Why Does a Diamond Cut Matter?

Although the terms "diamond cut" and "diamond shape" are frequently used synonymously, they are essentially two distinct concepts. A diamond's shape is defined as its outward figure or outline. On the other hand, a diamond's cut reflects its facets, reflective properties, symmetry, and size. A diamond's appearance, including its brilliance and fire, is directly influenced by the quality of its cut. That's why a diamond cut is so crucial.

How to Grade a Diamond Cut

The Gemological Institute of America (GIA) grades diamond cuts into four categories: 
  • Excellent 
  • Very Good
  •  Good
  •  Fair
  •  Poor. 
Not only does the cut quality of a stone determines how well it reflects light but also how much it costs.

Other Factors Affecting Price

The 4Cs of diamond quality (cut, carat, color, and clarity) are used to assess all diamonds. These, however, are not the only elements that can affect the final cost of a diamond engagement ring. The final price of a diamond will also depend on factors like
  • production expenses, 
  • the size of the stone when it is face up, 
  • and its durability.

What is the Most Expensive Diamond Cut

The round brilliant diamond cut is the most expensive.

Why is The Round Brilliant Cut The Most Expensive?

High Production Cost

The round brilliant diamond wastes the highest amount of rough stone during the cutting process, about 60% on average. Because there is so much waste, people will purchase a larger stone than they receive to cover expenditures.

Most Popular

In addition to being the most expensive diamond cut to produce, round diamonds are also the most popular stone shape for engagement rings and many other types of diamond jewelry. In fact, round brilliant cuts account for close to 75% of all diamonds sold globally.

Unmatched Sparkle

The unmatched sparkle of these stones is the key factor in their popularity. The round brilliant cut outshined every other popular diamond shape in terms of sparkle and brilliance. Round brilliant cut diamonds are also a great choice for almost every engagement ring. This makes them incredibly flexible gems that look gorgeous in any style.

What About The Least Expensive Cut?

Enjoy knowing that you will be saving money if your ideal diamond isn't round. Fancy forms like pear cuts, marquise cuts, and oval cuts offer much more yield than a round brilliant cut diamond, which loses more than half of its rough material after its cut. When creating other well-known shapes like the cushion cut diamond, Asscher cut diamond, and emerald cut diamond, diamond cutters squander even less rough diamond.
