She traveled to London during 1897, the year of Queen Victoria's Diamond Jubilee, in the hope of finding a buyer for her rubies and other jewels to raise funds for the university, but she wanted more than what they were worth and was unable to sell as many as she had hoped. In 1905, she directed the university trustees that after her death, her jewels should be sold and the funds used as a permanent endowment "to be used exclusively for the purchase of books and other publications." The board of trustees confirmed that arrangement, and the Jewel Fund continues to add to the university's library collections. The endowment, originally $500,000, is now worth about $20 million. Items purchased through the Jewel Fund display a distinctive bookplate that depicts a romanticized Jane Stanford offering her jewels to Athena, the Greek goddess of wisdom. Since 2007, benefactors who provide endowments for library acquisitions are referred to as members of the Jewel Society.
