The Ideal Cut Diamond

Over 200 years ago the Tolkowsky diamonds dynasty was born. Since the 1800's through to today the Tolkowksy name has been synonymous with cutting the worlds finest diamonds. Now Tolkowsky diamonds are avaliable exclusively at Ernest Jones.

The Ideal Cut

Tolkowsky is celebrated for creating the modern Ideal Cut Round Brilliant diamond. A diamond with 57 perfectly proportioned facets and precision symmetry.

This level of cutting perfection is very important, as if a diamonds proportions are not precise there may be areas where light can escape and in places the diamond will look dull and dark instead of bright and lively.

To prevent this loss of beauty, Marcel Tolkowsky set out to define the perfect parameters that a diamond would need to be cut to in order to maximize light return in 3 specific areas; brilliance (white light), fire (colour) and scintillation (overall sparkle). He succeeded and in doing so had invented what would come to be known as the 'Ideal Cut' Round Brilliant. His discovery became the benchmark light performance cut by which all other diamonds are judged.

Hearts & Arrows

The Hearts & Arrows optical effect is your visual proof of Tolkowsky's cutting perfection. The hearts and arrows image seen through the viewer shows you that due to the precision of the cut, the maximum amount of light is being reflected back out of the diamond. Every Tolkowsky round brilliant diamond displays eight hearts and eight arrows associated with the most perfectly crafted Ideal Cut Diamonds, a mark of true quality.

History

From the invention of the Ideal Cut , to cutting the world's largest diamonds, Tolkowsky have been perfecting diamond cutting for over 200 years.

Tolkowsky Diamond Dynasty

Over 200 years ago, a dynasty of precision, passion and perfection was born - the name of which would change diamonds forever. This diamond dynasty began with Abraham Tolkowsky, a talented artisan who established himself as an eminent jeweler to nobility.

The Ideal Cut

In 1919 Marcel Tolkowsky wrote his groundbreaking paper, Diamond Design. His revolutionary observations established the precise proportions of a diamond's cut needed to maximize its brilliance and dispersion of light. He had invented the Ideal Cut and changed the way we look at diamonds forever.

The Ideal Cut became the benchmark by which all other diamonds are judged to this day.

Master diamond cutter

Abraham Tolkowsky's great grandson Gabi followed in the family footsteps too and became a diamond cutter under the guidance of his father, Jean. In 1988 Gabi Tolkowsky had become the leading master diamond cutter in the world and was approached by De Beers to examine a diamond of extraordinary size, colour and clarity

De Beers Centenary

Gabi was commissioned to cut this remarkable 599ct rough crystal into the "The Centenary Diamond" to mark the 100 year anniversary of De Beers. Assisted by his son Jean Paul and a specialist team of scientists and polishers the project took 3 years. When it was finished, it presented 247 facets and weighed 273.85 carats. Gabi had crafted the largest, D colour flawless modern cut diamond in the world. In 1991 he bought The Centenary Diamond to London and personally presented the stone to Queen Elizabeth II at Buckingham Palace

Golden Jubilee Diamond

During the same period Gabi Tolkowsky also designed and cut the Golden Jubilee diamond, which is recognized as the largest faceted diamond in the world. Presented to HM King Bhumibol Adulyadej of Thailand to celebrate his 50 years on the throne. This glorious stone presents 148 facets and weights 545.65 carats and has a yellow-brown colour intensified by the fire rose cushion cut.

The Ideal Cut Princess

The Tolkowsky family tradition of cutting excellence continues to this day as in 2009, Jean Paul Tolkowsky perfected the Ideal Cut Princess Diamond. Working to the same principles as set out by his great uncle Marcel, Jean Paul optimised the princess diamonds square cut parameters in order to make it Ideal.
