[10] During her time at the Boston Square Theatre Jewel also appeared in a number of Shakespearean productions such as The Merchant of Venice (Jessica), The Taming of the Shrew (Bianca), Hamlet (the Player Queen), and As You Like It (Celia).

[4][12] For the 1905–06 season, Jewel joined the Proctor Stock Company in New York City, where she was well received portraying Hugette in If I Were King;[13] Stella Darbisher in Captain Swift;[14] Florence Sherwood in Northern Lights and Antoinette De Mauban in The Prisoner of Zenda.

[15][16] On October 6, 1906, in the aftermath of the San Francisco earthquake, Jewel starred in the first production at the city's new Colonial Theatre, as Clementina Fitzhugh in The Man from Mexico.

[17] Upon her arrival in San Francisco in mid September, Jewel received the news that her father had been killed in a train-pedestrian accident shortly after she and her mother had left for California.

As a result, on January 3, 1910, she made her Broadway debut at the Garrick Theatre as Margaret Druce to Skinner's Lafayette Towers in the hit play, Your Humble Servant.

[27][28] On April 3, 1921, Jewel was among a delegation of fifty members of the National Woman's Party (NWP) that met with President Warren G. Harding urging his support to call a special session of congress to address discrimination against women.

[30] By 1922 Jewel was a leading figure behind the Women's Committee of the American Farm Bureau Federation that lobbied for reforms to help improve the lot of rural farmers and their families.

[21][40] She was a tireless advocate of the League of Nations and had met with the boy emperor Puyi during a trip to China and the Italian dictator Benito Mussolini while in Rome for a suffragette conference.

The last few years of her life were spent at the Torrey Pines Convalescent Center in La Jolla where, on her 90th birthday, she was paid a visit by actors Helen Hayes and George C. Scott.
