Diamond Divas, a glitzy show of diamonds owned or worn by women of the glitterati, will open in Antwerp on April 11th at the Antwerp Diamond Museum. If you're fortunate enough to be in the area when the show is on, you'll be able to see the 24.04-carat canary yellow pear-shaped diamond that Marilyn Monroe wore to the premiere of "Gentlemen Prefer Blondes" and the tiara that Madonna wore when she married British director Guy Richie. Other pieces showcase the tastes of crowned heads like Empress Josephine, Countess Mountbatten of Burma, Queen Elizabeth of Belgium, and others. If, like most of us, you're unable to attend the show (it ends June 8, 2008), the Web site's gallery is worth a peek.

The exhibit is based on a book of the same name written by Vinciane van Grotenhuis van Onstein. She wanted to explore the link between exceptional women and exceptional jewels, whether in the form of power, freedom, or fashion. The book is due out on April 10, 2008.
