ters, the sixth generation of the Tolkowsky family to make his name in the trade. He is the great nephew of Marcel Tolkowsky
, the father of the modern round brilliant diamond cut.
Isadore and Sam now worked closely alongside their brother Maurice, and their father Abraham. In what was to be a long list of family firsts, Maurice invented the first diamond bruiting machine, which is fundamental to creating a perfectly round diamond. And brother Sam was elected the first chairman of the Antwerp Diamond Exchange.
In 1898, Isadore Tolkowsky celebrated the birth of his son, Marcel. As it turns out, Marcel would give his father more cause for celebration. Marcel went on to discover the proportions for the Modern Cut round diamond.

, a task which took three years. This monumental diamond remained untouched for over a year while the correct tools and technical conditions were created by Gabi and his team. The gem was kerfed (hand cleaved) in order to avoid heat- or vibration-related damage from saws or lasers. Finally in 1991 the Tolkowsky’s De Beers Centenary Diamond was finished weighing 273.85 carats (54.8 g) presents 247 facets and is acknowledged as the largest, most colour-perfect and flawless modern diamond cut in the world.
The Gabrielle Diamond in the Round shape consists of 105 facets, 48 facets more than the Classic Round Brilliant cut (with additional 8 crown facets and 40 pavilion facets). The Gabrielle Diamond was shown by a Light Study to exhibit 200% more scintillation than an excellent-cut classic brilliant diamond, and at the same time exhibited significantly greater brilliance and fire. This was achieved by increasing the "journey of light" within the diamond, so that the diamond appeared to sparkle from all angles.
Another 11 shapes were created, and the Gabrielle Diamond is now available in Marquise, Oval, Pear, Heart, Cushion, Radiant as well as the classic Round shape.
The Gabrielle Diamond is now sold in many countries, including the USA, Singapore, Australia, Japan and Germany.
