The blonde's ex fiancé is getting rid of his trash in the hopes it becomes someone else's treasure.
Waldeck has listed her old engagement ring on Gumtree.
The Daily Telegraph reported that 'Dave of Kurralta Park' has listed the used sparkler for the heavily discounted price of $12,400.
The seller, believed to be Waldeck, says the "one-of-a-kind 3.56 carat Ceylon sapphire gem and diamond ring has been certifiably valued at $19,150."
The seller adds that the ring is in "perfect condition with no marks or scratches" and describes it as having been custom-made from Wishart Jewellers.
The former couple started dating soon after she appeared on the inaugural season of The Bachelor in 2013.
In 2015, Ali gushed about her then-new man.
"Tim absolutely led me to Dave and he is the most perfect man in the world," she told news.com.au prior to her engagement.
She added: "The Bachelor was my hurdle and my challenge and something I learnt from and made me more of who I am today and Dave is the one for me."
Dave proposed in June 2015, after he and Ali enjoyed a romantic trip to Europe together.
