A Brief History of the Round Brilliant Cut
While diamonds have been admired for centuries, the round brilliant cut as we know it today only emerged in the early 20th century.
- 17th Century: Early round cuts, called “Old European cuts,” featured fewer facets and less sparkle.
- 1919: Marcel Tolkowsky, a Belgian mathematician, introduced the modern round brilliant cut, calculating precise angles to maximize fire and brilliance.
- Present Day: The round brilliant remains the gold standard of diamond cutting, constantly refined with advanced technology.
Choosing a round diamond engagement ring connects you with a century-long legacy of romance and innovation.
