Tolkowsky Heritage

The Tolkowsky family have been synonymous with diamond excellence for seven generations. Creative inspiration, mathematical genius, technical innovation and superb craftsmanship have consistently played their part.

The story of the Ideal Cut

In 1919 Marcel Tolkowsky invented the Ideal Cut diamond, a precise set of mathematical proportions that maximises the 3 elements of light in the diamond:
Brilliance, Fire and Sparkle

Today the TOLKOWSKY IDEAL CUT remains celebrated as the finest method of cutting round brilliant diamonds. All Tolkowsky Ideal Cut centre diamonds are guaranteed to achieve the highest rating of 'Very High' in all three light performance ratings on the GemEx report.
