Madison Beer’s Engagement Ring Might Look Bigger Than It Actually Is

Singer Madison Beer and NFL player Justin Hebert recently announced their engagement. In photos, Beer showed off her large new engagement ring. A jewelry expert weighed in on the cut, size, and likely cost of the diamond ring. While it is a large piece of jewelry, he estimates that it may look bigger than it actually is.

In a post shared to Instagram, Beer revealed that she and Herbert are going to tie the knot. “Meet my fiancé,” she wrote in the caption of a series of photos of his proposal. 

The couple first sparked relationship rumors in August 2025. Since then, she has been seen supporting him at many of his games. Herbert also appeared in the music video for Beer’s song “lovergirl.”

An expert examined Madison Beer’s engagement ring from Justin Herbert

In Beer’s post, she showed off her large diamond engagement ring. It has an elongated radiant cut, which has a rectangular shape. Oliver Hobart, a jewelry expert and Creative Director at 925E, gave an estimate of the ring’s size. It may appear larger than it truly is.

“Working from the ring’s proportions against Madison Beer’s finger and knuckle in these photos, I’d estimate the central stone at somewhere between 8 and 10 carats if not larger, a genuinely substantial size,” he explained. “Elongated cuts like this tend to read even larger than their actual carat weight, because the eye reads length as size before it registers width.”

The diamond is the star of the show in this ring.

“The band appears to be a plain or very finely set shank in a white metal, most likely platinum, with no visible halo,” Hobart said. “Nearly all the design and budget has gone into the stone itself rather than the surrounding setting, which is a deliberate choice.”

Given this estimate, he shared what he believes the ring may have cost Herbert.

“At an estimated 8 to 10 carats, and assuming a colourless to near-colourless grade with good clarity, which is typical for a stone of this calibre and prominence, I’d value this ring somewhere in the region of £180,000 to £280,000 ($240,000 to $370,000) if not more,” he said. “It’s a wide bracket, because cut quality and colour grade move the price enormously at this carat weight, and neither can be pinned down precisely from a photograph. But that’s the realistic range.”

Madison Beer’s engagement ring has a popular cut

While radiant cut diamonds look similar to emerald cuts, Hobart explained that there is a difference between the two.

“This stone is throwing far more sparkle than [an emerald cut]. A radiant cut takes the same elongated rectangular outline but cuts the facets underneath differently, to bring in the fire you’d normally get from a round stone,” he said. “You can see it catching light along almost the full length of the stone rather than in one central flash.”

These cuts have become very popular amongst celebrities in recent years. Beer’s ring has only further driven up interest.

“Radiant cuts have become one of the most popular choices for engagement rings over the past few years, worn by the likes of Hailey Bieber and Ariana Grande, so this isn’t an obscure pick on Herbert’s part,” he said. “It sits in a real sweet spot: the elongated, elegant silhouette of an emerald cut, with significantly more brilliance and sparkle. That combination is exactly why it’s had such a moment.”
