Celebrities don’t all wear the same kind of diamond ring, and their choices are steering what others now want. The usual round cut? Less common among them than expected. While 63% of non-celebrity rings still favor round diamonds, only about 30% of celebrity rings follow that route. Celebs seem more into bold or unique styles that grab attention while still showing off the stone.
Cushion, Oval, Emerald: The Chart-Toppers
Meghan Markle’s cushion-cut trilogy ring continues to be one of the most liked. A 2025 poll by the Natural Diamond Council listed it as the top pick among 2,000 UK adults. It has a center stone from Botswana and two side diamonds that were once owned by Princess Diana. Zendaya’s ring came in second—a rare east-west oval cut that sits sideways instead of upright.
Hailey Bieber and Kourtney Kardashian both chose oval diamonds too. Hailey upgraded to an 18-carat oval in 2024, worth about $1.5 million. Oval shapes have been climbing with Gen Z, with 17% of those aged 18–24 choosing that style by early 2025. The elongated shape makes the stone look bigger. Less waste during cutting also makes ovals cost 20–30% less than round diamonds of the same carat.
Emerald cuts hold their spot in celebrity jewelry. Lauren Sánchez wears a 30-carat emerald-cut ring that sits in the $3–5 million price range, while Beyoncé’s 18-carat version is often listed in top celebrity ring roundups. Emerald cuts use step facets for clarity and symmetry but don’t sparkle as much as brilliant cuts.
Shapes That Got People Talking in 2025
Some engagement rings cause a stir not because of price but because of shape. Blake Lively’s 12-carat pink oval still trends online, but Megan Fox’s Toi et Moi combo—pear diamond and emerald—got even more buzz. That pairing reminded folks that not every ring follows round or cushion rules.
When Florence Pugh flashed a bold emerald cut, fans praised its clean lines. But others zoomed in on the second design element: a hidden halo. Meanwhile, ring watchers pointed out that a few stars—like Victoria Beckham and Cardi B—prefer a bold look like a round or pear shaped engagement ring paired with exaggerated halos or thick-set bands.
What the Numbers Say
In 2024, the average celebrity ring carried a 5.2-carat diamond. Among non-celebrities, the average was 1.8 carats. Lab-grown diamonds made it easier for people to go bigger without spending millions. Around 52% of engagement rings in 2024 used lab-grown stones, up from 21% in 2022.
Search activity shows people pay attention. Zendaya’s ring sparked a 310% rise in custom requests for east-west ovals. Lady Gaga’s oval-cut design got 728 news mentions and 196 viral posts on X (formerly Twitter), according to Pandora’s 2024 report. Instagram views on ring hashtags like #EngagementRing and #OvalCut reached over 2 billion.
Under-The-Radar Trends
Historical cuts like cushion are gaining again. Once called “old mine cuts,” they’ve been around since the 1700s. Radiant cuts, invented in 1977, are a blend between round and emerald cuts, giving more sparkle but keeping a rectangular look. Radiants have between 61 and 70 facets, compared to round brilliants’ 58.
The bow-tie effect — dark shadows across some fancy shapes like oval or marquise — is also something buyers care about now. It can be fixed with better cutting, but poorly cut versions show it more.
Katy Perry broke from the white diamond pattern altogether, with a bright ruby in a flower-like halo. About 22% of 2024 brides reportedly chose non-white stones for their rings. Same for Megan Fox, whose Toi et Moi design combines a pear-shaped diamond and a green emerald linked with thorn-covered bands—yes, really.
What’s Taking Off in 2025
Vintage styles and Art Deco details are picking up steam. Paris Hilton’s ring channels that, with a 15- to 20-carat emerald cut and trapezoid side stones. Searches for “Art Nouveau engagement ring” jumped 89% in early 2025. Zendaya’s ring also led a mini-trend toward east-west settings, copied in 18% of new custom orders.
Colored gemstones are becoming more common among shoppers under 30. A recent comparison showed 52% of Gen Z buyers now consider colored diamonds, up from 19% five years ago. Dakota Johnson’s 8–10 carat emerald ring shows that shift, blending elegance with color without going too far off course.
In Short
Round diamonds are still selling more than anything else, but among celebrities, they’re outnumbered by ovals, cushions, and emeralds. Unusual settings, color, and size help make each ring stand out. And for everyday buyers, lab-grown stones are what’s making those bigger dreams possible. Keep your eye on cushion cuts and sideways-set ovals this year—they’re not going anywhere.
