As Marilyn Monroe famously proclaimed in Gentlemen Prefer Blondes, “Diamonds are a girl’s best friend.” Now, thanks to Julien’s Auctions, you can snag the very same diamonds she sang about in the film, along with several other stunning old Hollywood baubles, with pieces going to the highest bidder.

Starting tomorrow, November 18, the auction house will debut its Joseff of Hollywood: Treasures from the Vault sale, allowing the mere mortals among us to bid on more than “600 unique pieces of costume jewelry and accessories [both from films and red carpet appearances as] worn by Hollywood’s most glamorous stars of the 1920s, 1930s, and 1940s.”

Some of the items up for auction include a brooch worn by Marlene Dietrich in Shanghai Express (1932), a pair of earrings and ornaments worn by Greta Garbo in Camille (1936), a necklace worn by Vivien Leigh and a cigar case used by Clark Gable in Gone With the Wind (1939), a pair of earrings worn by Marilyn Monroe in Gentlemen Prefer Blondes (1953), and a pair of earrings worn by Marilyn Monroe in Some Like It Hot (1959).

You can bid via online livestream starting tomorrow at 1pm/12c.
