Caitlin O'Connor's Massive 7-Carat Engagement Ring: A Custom Design by Joe Manganiello

Caitlin O'Connor’s engagement just became impossible to miss, as a dramatic second ring quietly tells a deeper story about romance, timing, and a very personal design choice by Joe Manganiello.

Caitlin O'Connor is showing off a striking new engagement ring, one that comes with both size and sentiment. The actress and television host recently revealed that Joe Manganiello gifted her an upgraded diamond ring that he personally designed, replacing the original piece he used when he proposed.

According to O'Connor, the new ring carries special significance for the couple. She describes it as a 7-carat round-cut diamond set on a pavé band, framed by a halo of smaller diamonds that amplify its brilliance. The design is bold but intentional, reflecting Manganiello’s hands-on role in creating something uniquely theirs.

"It is the most beautiful thing I have ever seen and has special meaning to us as a couple," O'Connor says, adding that the ring feels deeply personal rather than simply extravagant.

A Romantic Proposal Beneath Mount Etna

Manganiello proposed on June 24, 2025, during a trip to Italy, choosing a location that matched the scale of the moment. O'Connor reveals that he got down on one knee beneath Mount Etna, the active volcano located on Sicily’s eastern coast.

The setting, dramatic and historic, made the proposal unforgettable. O'Connor describes the experience as intensely romantic, underscoring how much thought Manganiello put into the occasion.

When the couple publicly confirmed their engagement months later, they shared a photo on Instagram on Oct. 17, 2025, giving fans a first look at the original engagement ring. At the time, there was no mention of a second ring or a redesign, making the later reveal an unexpected surprise.

"I am very excited to be engaged to my love," O'Connor says, expressing her happiness as the couple steps into their next chapter together.

The Ring’s First Red Carpet Appearance

O'Connor debuted the upgraded ring in public during the opening night premiere party for the 2026 LA Art Show in Los Angeles on Wednesday, January 7, 2025. The appearance marked the first time the custom-designed piece was seen outside social media, immediately drawing attention.

Leaning into a bridal-inspired look, O'Connor wore a white floral corset paired with black bottoms, allowing the oversized diamond to take center stage. The contrast between her outfit and the sparkle of the ring made it a standout accessory on the red carpet.

A Relationship Shared With Fans

O'Connor and Manganiello have been together for nearly two years, and their relationship has unfolded largely in the public eye. Both regularly share glimpses of their life together on social media, from travel moments to everyday snapshots that highlight their close bond.

Their engagement has been met with enthusiasm from fans, many of whom have followed their relationship since its early days. The addition of a custom-designed ring only adds to the sense that this engagement is deeply intentional and thoughtfully planned.

Before his relationship with O'Connor, Manganiello was married to actress Sofia Vergara. He filed for divorce in July 2023, citing irreconcilable differences. The marriage was his first, and the separation marked a significant turning point in his personal life.

Now, with a new engagement and a ring designed by his own hand, Manganiello appears to be fully embracing a fresh start. For O'Connor, the upgraded diamond is more than a statement piece. It is a symbol of where they have been and where they are headed next.
