Jewel destination

DeBeers hires one of the best diamond cutters in the world, Gabi Tolkowsky , and is tasked with cutting and polishing the Centennial diamond. The work itself was carried out in a specially constructed room at the DeBeers Diamond Research Laboratory and took three years alongside the team of experts.

The first step consisted of polishing the Centennial Diamond by hand removing the 20-carat diamond to give it the first shape, this part of the delicate process took 154 days. After this first stage, Tolkowsky and his assistants created 13 sketches of possible cuts and were presented to the DeBeers board , which finally selected a modified heart shape for the Centennial Diamond. The final cut of the Centennial Diamond, lasted about a year, and was heart shaped at 273.85 carats and with a record of 247 facets and two additional diamonds that came out of the cuts, pear shaped respectively.
