IN 1919, MARCEL TOLKOWSKY CHANGED DIAMONDS FOREVER. The Ideal
Cut Diamond was born of academic study. Marcel Tolkowsky wanted
to determine the precise proportions of a diamond’s cut to
maximize its brilliance and dispersion of light. His studies
proved that if a diamond was cut too shallow or too deep, light
escaped from the bottom and sides, resulting in a loss of fire,
sparkle and brilliance from the top. This led to the creation of
the Ideal Cut diamond, prized for its ability to bring forth the
fire and brilliance hidden in the heart of the diamond. The
Ideal Cut remains the benchmark for industry excellence and the
name Tolkowsky synonymous with unsurpassed excellence.
