Celebrating Round Diamonds

The round diamond is the most popular shape of all diamonds, accounting for approximately 75% of all diamonds sold. Thanks to its shape, the round diamond is generally the sparkliest of all diamond shapes because it has the most facets. And most round diamonds are brilliant cut— which means they have 58 facets!

Because most of the rough diamond is lost when cut into a round shape, a round shape diamond carat quality is generally higher. This means round diamonds are slightly more expensive than other diamonds. But don't let that deter you...if you want a round diamond for your engagement ring, the perfect one will be out there waiting for you!

In 1919, the publication of Marcel Tolkowsky's thesis—Diamond Design: A Study of the Reflection and Refraction of Light in Diamond helped the round diamond begin its climb in popularity.

Tolkowsky's work described the ideal proportions of a round cut diamond for maximizing brilliance and fire. These are what make a diamond sparkly and have flashes of light, and round diamonds are ideally-shaped for these attributes. And this is what draws your eye to them—the sparkle!

Tolkowsk's original specifications have been perfected over time as advancements in cutting and technology have been made. It's why you see such incredibly "brilliant" round diamonds on the market today!

We here at Mullen Bros. Jewelers love round diamonds: the round cut is extremely versatile and adaptable to any hand size or shape. It is classic and elegant, and why it is loved and worn by so many ladies!
