Just two weeks after Travis Barker and Kourtney Kardashian tied the knot, the Blink 182 drummer’s ex-wife Shanna Moakler’s engagement ring is hitting the auction block.

TMZ reports Moakler, the former Miss USA winner who was married to Barker from 2004 and 2008, has joined forces with jewelry re-sale company Worthy to sell her 4-carat round cut solitaire diamond ring.

Bidding for Moakler’s ring, which began Friday and will run until Tuesday, starts at $51,000, but the former pageant queen thinks it should fetch more on the auction market.

“I’m hoping it sells for $120K. It was worth about $160K,” she told Us Weekly.

The 47-year-old added, “I think it is a beautiful piece and truly was my dream ring. However, that chapter of my life is over and even though wearing it at one time brought me great joy, I hope it will find a new home and continue to bring someone as much happiness as it once did to me. It’s truly an iconic ring!”

Barker and Moakler got married in 2004 and divorced four years later. The couple shares two children together, 18-year-old Landon and 16-year-old Alabama.

“With the activity we are seeing so far and the feedback we are getting from our exclusive network of professional buyers, we are confident that we will be able to reach Shanna’s reserve price,” Steven Schneider, CEO of Worthy, expressed to People.
