Titled 'Property from the Collection of Jane Fonda,' the event is scheduled to be held on September 23, reported People magazine.
Julien's Auctions, the house that has also sold items owned by Michael Jackson and Marilyn Monroe will be hosting the event.
The Collection of Jane Fonda is "a story of Fonda's life, representing different points in her celebrated career and personal life," the press release reads.
The lace gown and opal ring are from 1991, when Fonda, 78, married media mogul Turner, 77, in a Capps, Florida, ceremony.
Julien's estimates their worth between USD 2,000 to USD 4,000.
