mona_lisa.jpg Mona Lisa, or La Gioconda (La Joconde) is a 16th-century portrait painted in oil on a poplar panel by Leonardo Da Vinci during the Italian Renaissance. Is the most famous painting in the world. Owned by the French government and hangs in the Mouse du Louvre in Paris, France with the title Portrait of Lisa Gherardini, wife of Francesco del Giocondo.  
 Mona Lisa is the highest insurance value for a painting in history, In 1962 It was assessed at US$100 million . But the French Government decided to spend it in security instead. Insurance value now would be approximately US$670 million. Maybe the highest painting worth if only available for sale or auction.
