Eurostar, the Belgian-Indian diamond corporation, has introduced a new branded diamond cut called the “Blue Flame. The cut has 89 facets and goes with a specially designed line of jewelry, all made for Tesiro, a partnership between Eurostar and China’s Tongling Group that runs more than 150 retail jewelry outlets in China.

The Blue Flame cut was introduced in Antwerp, where it was designed by two master cutters, Bernard Van Pul and Koen Van Ishoven.

Its next stop is the Berlin Film Festival, which Tesiro sponsors. The new cut will appear in jewelry worn by film stars Nicole Kidman, Kate Winslet and Catherine Zeta Jones.
