The identity of an unnamed man who placed the winning $80,000 bid on Elizabeth Taylor's cherished emerald and diamond Bulgari ring at an AIDS charity auction has been revealed.

The man is Gus Davis, described as a New York jewelry dealer for Camilla Dietz Bergeron Ltd., a Madison Avenue gallery that specializes in antique and period jewelry.

"The ring holds a very sentimental value that is priceless, and we are honored to have it in our collection," Davis said in a statement. "It is even more meaningful that sales went to help the fight on AIDS."

Addie Morfoot, a spokeswoman for Davis, tells PEOPLE.com that although Camilla Bergeron does primarily sell the pieces in its jewelry collection, the Taylor bauble will be kept for exhibition purposes only. "There are no plans to sell it," Morfoot said.

She added that the public may view the piece -- which was originally given to Taylor in 1962 as an engagement present from Richard Burton -- by contacting Bergeron Ltd. and scheduling an appointment. "Ask for Gus," said Morfoot.

The auction at Christie's New York last Thursday coincided with the publication of the 70-year-old screen legend's new book, "Elizabeth Taylor: My Love Affair with Jewelry," and raised $258,000 for The Elizabeth Taylor AIDS Foundation., which over the years has distributed more than $8 million to AIDS organizations.

The Bulgari ring fetched the highest price.
