What Is the Most Expensive Diamond Cut?

It’s hard to look away from the sparkle of a diamond, and while it truly looks stunning in almost any shape, one particular diamond cut lets the diamond show off its beauty better than any other.

What is the most expensive diamond cut?


The round cut diamond is the most popular diamond shape, and also the most expensive. Round diamonds make up 75 percent of all diamonds sold, and it’s not hard to see why.


Because of its shape, the round diamond allows for a beautiful reflection of light, which makes this diamond sparkle the brightest.

Why Is the Round Diamond Cut More Expensive?

Go back and visit Economics 101 for a lesson on good ol’ supply and demand. Round diamonds are the most sought-after, so they are the most expensive. But that high price isn’t just because of demand. It also comes down to how the diamond is cut. The yield of a round diamond is relatively low, which means more of the rough stone is lost in the cutting of the round stone — making the resulting round diamond more valuable.

Each carat retained in a round shape maintains a higher cost — 25 to 35 percent more than any other cut, in fact.

It’s the Diamond That Sparkles the Most

We can all thank Marcel Tolkowsky for creating the round diamond shape in 1919. His round diamond results in 58 facets (or flat, polished surfaces), meaning the light bounces from the bottom of the diamond and back through the top. That sparkle of the round diamond is real and brilliant, and enough to make most anybody swoon.

The shape itself is also beautiful and timeless. A round diamond looks stunning in elaborate settings. And when placed in simple settings, it always looks modern and clean.



How to Get the Most Sparkle

Choose a round brilliant cut diamond in a prong setting, at the highest clarity and cut quality you can afford. Why prong? It lifts the diamond away from the band, allowing light to pierce the stone from almost every angle. Sparkle!
