Experts say France's royal jewels may be gone forever after a daring heist at the Louvre. On Sunday, thieves stole eight pieces, including crowns and necklaces, in just four minutes.

In total, thieves stole jewels worth about €88 million, including a necklace Napoleon Bonaparte gave to Marie-Louise of Austria, the tiara, necklace and earrings of Queen Hortense, and a diadem, diamond bow brooch and reliquary brooch that once belonged to Empress Eugénie, wife of Napoleon III.

Thieves used a stolen truck-mounted moving lift to scale the Louvre and steal royal jewels worth over $100 million in a lightning-fast Paris heist.

Prosecutor Laure Beccuau, who is leading the investigation, said in an Oct. 21 interview with RTL, a French radio network, the jewels are worth an estimated 88 million euros. That amounts to an estimated $102 million dollars. Beccuau said the value was derived by a museum conservator.

The French crown jewels robbed from the Louvre museum in Paris are likely lost forever, an art crime expert tells CBS News, even if the thieves are caught.
