Madison Beer's stunning engagement ring could be worth up to $1 million: Here's what makes it so rare

Madison Beer isn't just celebrating her engagement to NFL quarterback Justin Herbert—she's also showing off a dazzling engagement ring that's quickly become the talk of social media.

After announcing their engagement on July 28 with a series of romantic proposal photos, fans couldn't help but notice the singer's striking vintage-inspired diamond ring.

According to jewelry experts, the ring features an extremely elongated cushion-cut diamond set on a thin yellow gold band, allowing the center stone to take center stage. Ring expert Kegan Fisher described the diamond as exceptionally rare, with a length-to-width ratio approaching 2:1, making it particularly difficult to source.

Experts estimate the center stone weighs between 10 and 15 carats, with the ring's minimalist solitaire setting designed to showcase the diamond without distracting from it.

Jewelry designer Alison Chemla, creative director of Alison Lou, noted that the classic four- or six-prong solitaire setting keeps the focus entirely on the diamond.

The stunning piece is estimated to be worth between $500,000 and $1 million, making it one of the most eye-catching celebrity engagement rings of the year.

Beer and Herbert first sparked romance rumors in August 2025 before confirming their relationship months later. Since then, they've made several public appearances together, and Herbert even appeared in Beer's "Lovergirl" music video.

The couple announced their engagement with a series of intimate proposal photos, with Beer captioning the post simply, "Meet my fiancé."

While the proposal itself won over fans, it's Beer's rare cushion-cut diamond that's continuing to steal the spotlight.
