Marcel Tolkowsky
The Ideal Cut
Marcel Tolkowsky is globally celebrated as the father of the modern round brilliant diamond. Invented in 1919 Marcel mathematically calculated the exact placement of facets to achieve the best light
return possible in a 57 facet cut.
As the diamond industry began to recognise the importance of cut proportion and its effect on beauty, Marcels invention quickly became recognised as the highest quality possible and it was named the “Ideal Cut”. To this day, 100 years after its invention it remains the benchmark of cutting excellence.
Cut Proportions
Marcel invented the “ideal” proportions for a 57 facet diamond so that no light escapes through the pavilion of the diamond – all light returns through the crown facets and table for maximum fire, brilliance and scintillation.
