Tolkowskys

Tolkowsky is a surname with notable associations in the fields of gemology and diamond cutting. The most prominent figure bearing this name is Marcel Tolkowsky, a Belgian-born diamond cutter who is credited with developing the modern brilliant cut. He published his groundbreaking doctoral thesis on the subject in 1919, outlining the precise proportions and angles required to maximize a diamond's brilliance, fire, and scintillation. His mathematical calculations formed the basis for what is now known as the ideal or 57-facet round brilliant cut.

The Tolkowsky family has a long-standing history in the diamond industry. Louis Tolkowsky, Marcel's father, was also a diamond merchant and cutter. The family's expertise and innovations have significantly influenced the way diamonds are cut and valued. Today, the name Tolkowsky is often associated with high-quality diamond cutting and excellence in the gemological world. The principles established by Marcel Tolkowsky remain fundamental to diamond grading and appreciation, even with the advent of advanced technology in diamond cutting.
