Kim Kardashian is revealing some shocking new information about her infamous 72-day marriage to former NBA player Kris Humphries.

In the latest episode of The Kardashians Season 6 — titled “Kim and Khloé Take India — Kim says she was forced to return her 20.5-carat engagement ring to Humphries in their divorce, even though she paid for the majority of it.

Drenched in diamonds for the lavish Ambani wedding in India, Kim contemplates whether she should start wearing her expensive jewelry again. The Skims founder stopped flaunting her own diamonds in public after she was robbed at gunpoint in her Paris hotel room in 2016.

The reality star, who has been married and divorced three times, then wonders what her “next ring shape will be.”

“My last and final hurrah,” Kim jokes, referring to her potential fourth marriage.

Looking back on her collection of engagement rings, Kim says she still has her 14-carat cushion-cut ring from her first husband, Damon Thomas. She was only 19 years old when she eloped with the 28-year-old music producer, though he filed for divorce after nearly four years of marriage.

In 2011, Kim got engaged to Humphries after six months of dating. He proposed with a 20.5-carat emerald-cut diamond she bought from jewelry designer Lorraine Schwartz that was reportedly valued at a staggering $2 million. What’s more shocking than the fact that their marriage only lasted 72 days, however, is that Humphries demanded the ring back when they finalized their divorce in 2013 even though Kim allegedly footed the bill.

“I didn’t keep that [ring],” she says in The Kardashians. “I was pregnant with North, still married to him. And in order to divorce him, he said I had to give him the ring in my divorce — that I bought. He contributed a fifth.”

Humphries ultimately auctioned off the ring for $749,000 with plans to donate the proceeds to charity.

As for her third engagement ring (a 15-carat cushion-cut diamond), gifted to her by her ex-husband and the father of her four children Kanye West, Kim says she’s saving it for her eldest daughter, North West, because she was there for the engagement.
