Belgian mathematician Marcel Tolkowsky is responsible for the improvements that have created
our modern idea of the Round Brilliant. In his 1919 PhD thesis, he intended to calculate
the maximum potential of brilliance and fire of a diamond. He concluded that a diamond cut too deep
or too shallow reduces its brilliance, fire and sparkle.
Round Brilliant is the classic choice for most engagement rings. It is cut from octahedron-shaped
rough diamonds and looks beautiful as a solitaire (single stone) or combined with multiple jewels.
Resting closer to the hand, this diamond is less cumbersome to wear and is flattering to all types
of hands. Its flexibility in balancing color, fire and brilliance make it a perfect choice for any individual
looking for the well-rounded diamond.
