Kim Basinger is ridding herself of Alec Baldwin's last tokens of affection. The Oscar-winning actress (L.A. Confidential) wants to sell some of the jewelry her ex-husband gave her during their nine-year marriage.

Among them: the Tiffany engagement ring he gave her in 1993 after he became besotted while making The Marrying Man. (The auction house estimates the value of the 3.7-carat diamond mounted on an 18-karat gold band between $30,000 and $40,000.)

Proceeds from the sale will benefit retired animals assisted by the Performing Animal Welfare Society.

Basinger's jewelry will be at Christie's in New York, 20 Rockefeller Plaza. Bidding begins at 10 a.m. April 20.
