The 35 baguette-cut diamonds ring was given to the 'Gentlemen Prefer Blondes' star by legendary New York Yankees baseball player, Joe DiMaggio on their wedding day in 1954.
The starting bid for the ring is reported to start at 300,000 dollars, Contactmusic reported.
Initially the 'Profiles in History' auctioneers had decided to highlight the Icons of Hollywood sale with the ruby slippers, which Judy Garland wore in 'The Wizard of Oz', but now they have gone ahead with more than they had earlier planned.
A naked painting of the tragic movie icon when she was young by Earl Moran in the 1940s has also been added to the celebrity memorabilia auction cart, bids for which are set to start at 70,000 dollars.
