Amelie Mauresmo will have to overcome the home crowd in Antwerpto secure some diamonds.
The top seed and two-time defending champion moved into the final of the 600,000 Proximus Diamond Games on Saturday with a 6-2 3-6 6-2 victory over No 7 Anna Chakvetadze of Russia.
Awaiting the Frenchwoman in the final is second-seeded Belgian Kim Clijsters, who is retiring at the end of the season. A win in her final appearance here likely would have special meaning.
Clijsters, who won here in 2004 and was a finalist in 2003 and 2006, cruised to a 6-4 6-3 triumph over unseeded Tatiana Golovin of France on Saturday.
Mauresmo is seeking a stunning diamond-studded tennis racquet which goes to any player who wins three times in a five-year span.
She has failed in bids to defend two titles this year, falling in the fourth round of the Australian Open and in the semi-finals of the Open Gaz de France.
A win would give Mauresmo her 24th career title. Clijsters is seeking her second title of the year and 35th career.
