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.

All Tolkowsky diamonds are guaranteed to score a minimum of two “VERY HIGH” ratings in the measurements of Brilliance, Fire and Sparkle, as shown here in the blue bands. The red bands represent the light performance of a conventional cut diamond of comparable quality and weight.

Every Tolkowsky Diamond is accompanied by a GemEx Certificate as proof of the diamond’s superior light performance. All Tolkowsky center diamonds are certified Ideal Cut and come with a certificate of authenticity and gemological certificate from an independent diamond grading laboratory.

Established over 200 years, Tolkowsky is popularly regarded as the foremost name in the diamond industry. It is impossible to study diamonds as they exist today without paying homage to the name Tolkowsky. The family's passion, position, and ongoing pursuit of perfection are universally acknowledged.
