Pamela Anderson has auctioned off her engagement ring from her ex-husband Rick Salmon - all in the name of charity.

"I hope this very special Tiffany engagement ring can bring joy to someone while I put the donation to great use," Anderson said in an interview with People.

"One hundred percent of funds raised will go to The Pamela Anderson Foundation and this will mark the launching of my foundation's new eBay charity store, where there will be signed books and memorabilia."

The former "Baywatch" star's engagement ring has a 3.24-carat round vivid cut diamond stone that is enclosed by a layer of equally round vivid cut diamonds that weigh .46-carat.

The starting bid for the vivid diamond cut bling will begin at $100,000, E! Online reported.

Anderson wed Salmon back in 2007 before their marriage was annulled two months later.

They reconciled sometime in 2013, and she revealed in January 2014 that they got married once again. However, she ended up filing for divorce back in July, according to dBTechno.
