Thieves steal $500K in jewels from Paris apartment of French actress and her prince husband

French actress Clotilde Courau is married to Prince of Savoy Emanuele Filiberto.

Paris -- Paris thieves made off with an estimated half a million dollars' worth of jewels in the burglary of a high society French couple last week, according to reports.

The Paris apartment of French actress Clotilde Courau and her husband Emanuele Filiberto, the Prince of Savoy, was burglarized on Friday.

The French newspaper “Le Parisien” and other media outlets reported that the actress and the Italian prince were not at home at the time of the burglary.

Filiberto, a member of Italy's House of Savoy, is the only male-line grandson of Umberto II, the last King of Italy. Last year he called for the restoration of Italy’s monarchy and the establishment of a brand-new monarchy party to lead Italy.

Authorities say the ancient jewels of royal families have a well-known pedigree. At the couple's Rome wedding in 2003, Courau wore a tiara of pink topaz and diamonds that had belonged to Queen Maria Theresa of Sardinia.
