According to engagement ring expert Nilesh Rakholia, founder of Abelini, Garner’s four to five-carat diamond ring, suspected to be from longtime partner John Miller, has an estimated value of $250,000 — half the value of the engagement ring she was given by ex-husband Ben Affleck, HELLO! reported.

Despite growing speculation, Garner has not yet confirmed if she and Miller are engaged to be married after dating for eight years.

In a previous interview with PEOPLE two years after she began dating Miller, the “13 Going on 30” actress shared that getting married after her 2018 divorce from Affleck, father to her three children, Violet, Fin, and Samuel, wasn’t a priority.

“I don’t know. I’m so far from it. And I don’t know that marriage would need to be a part,” Garner said. “I mean I definitely don’t think that I’ll be single forever. But this is not the time. I don’t need to complicate it; I’m good.”

At the time, Garner also confirmed that she has no plans to expand her family and welcome more children. “Yes, the shop is closed; there are no babies,” she shared.

Just last year, a source close to the couple shared with PEOPLE that Garner and Miller’s relationship was “better than ever” adding, “John has also embraced Jen’s family life. He’s been patient, supportive and deeply respectful of her dynamic with Ben and the kids.”

After dating for two years, Garner and Miller briefly split in 2020, later getting back together in 2021. According to Us Weekly, the Cali Group CEO was ready to get married while Garner was in no rush to walk down the aisle again after separating from Affleck in 2015.

“They parted on very amicable terms,” the insider added of Garner and Miller.

In a recent interview with HOLA!, Garner shed light on her relationship views, explaining how even if a romance ends, there’s always something to look forward to.

“Every relationship is almost a different kind of love, and you get something from each relationship,” she said.

Before she married Affleck, Garner was married to actor Scott Foley from 2000 to 2004. She told The Sun in a previous interview, according to Page Six, that going through a divorce was one of her biggest heartbreaks.

“I did marry in my twenties and I found divorce a crushing experience,” Garner shared. “I thought the divorce statistics would never apply to me. I was beyond heartbroken when they did.”
