Millicent Fawcett’s "Steadfastness and Courage" brooch is to go on permanent display at the Museum of London.
The gold and enamel piece was made for the leader of the National Union of Women’s Suffrage Societies (NUWSS) by her members.
Fawcett spent her life campaigning for women’s suffrage and equal rights. She was president of the NUWSS, the largest non-militant suffrage campaign group, between 1907 and 1919.
She regularly wore the brooch, often as a pendant, and it is included on the statue of her unveiled in Parliament Square in April 2018.
Social & Working History Curator Beverley Cook said the piece "enables us to represent the key role played by those women who fought constitutionally for the right to vote without taking direct militant actions".
The piece is on long-term loan from the Fawcett Society and will be on display in the People’s City Gallery from Friday.
