The Geneva jeweler owned in part by the husband of Isabel dos Santos, the billionaire facing allegations of having pilfered Angolan state-owned companies, filed for bankruptcy.

De Grisogono SA failed to secure a buyer despite talks that lasted several months, the company said in a statement on Wednesday morning. The failed negotiations forced the company to file for creditor protection with Swiss authorities, which if accepted, will affect 65 jobs in Switzerland, the company said.

Dos Santos has said the allegations against her are part of a political witch hunt to discredit her and that she made her fortune as a self-made businesswoman.
