The couple’s announcement was sweet, understated, and entirely swoon-worthy. But let’s be honest, the real scene-stealer was the blinding oval-cut diamond glittering on Saint Mleux’s left hand, a rock so luminous it could probably guide a Ferrari through the Monaco tunnel at midnight.
Leclerc, the 28-year-old Formula 1 driver known for his precision on track and immaculate taste off it, reportedly proposed with a ring valued at over half a million dollars. According to jewelry experts, the dazzling piece isn’t just a testament to love, it’s shaping up to be 2026’s defining bridal trend.
According to jewelry specialists, Saint Mleux’s engagement ring features a classic oval-cut solitaire diamond set in a slim prong-style band, with pavé diamonds delicately lining the shank.
The ring’s minimalist silhouette highlights the diamond’s elongated shape, allowing it to catch maximum light while maintaining an elegant and balanced profile.
Experts estimate the center stone to be over five carats, a size that offers “significant presence while staying in proportion with Saint Mleux’s slender hand.” Based on its craftsmanship, clarity, and cut, the ring’s value is estimated at over $500,000, an exquisite blend of refinement and restraint.
The oval cut itself has long been a favorite among modern brides, combining the timeless elegance of a round diamond with the elongating effect of a marquise.
It’s the kind of cut that feels both regal and fresh, which is probably why it’s been spotted on everyone from Hailey Bieber to Phoebe Tonkin. Saint Mleux’s ring, however, manages to stand apart, capturing the essence of quiet luxury with a high-fashion edge, much like her own personal style.
It’s no surprise that Alexandra Saint Mleux, the 23-year-old art curator and fashion darling of the F1 paddock, would deliver a masterclass in modern engagement style. Her proposal ensemble, a duck-egg blue bias-cut silk slip dress, struck the perfect balance between effortless and ethereal. The gown’s halter neckline, low back, and lace trim whispered romance without ever shouting it.
And then there were the details: diamond Chanel interlocking C studs, a fine gold bracelet, and that ring, gleaming brighter than the Monaco sun. The overall effect was so polished, so quietly glamorous, that it practically redefined what a proposal look could be.
The couple shared the news via Instagram with a carousel of photos featuring their dachshund, Leo Leclerc Saint Mleux, wearing a tag that read “Dad wants to marry you!” (because every perfect love story needs a cute dog cameo). But between the puppy and the proposal, it was the diamond that truly captured the internet’s attention.
There’s something deeply romantic, and incredibly photogenic, about the oval cut. The shape elongates the finger, maximizes sparkle, and feels softer than sharp-edged alternatives like the emerald or princess cut. Experts say the cut’s growing popularity lies in its “modern versatility,” fitting seamlessly with both minimalist settings and vintage-inspired bands.
And much like the woman wearing it, Saint Mleux’s ring is a study in balance: contemporary, yet timeless; bold, yet delicate. In a world obsessed with statement pieces, it’s the kind of understated grandeur that speaks louder than carats alone.
As Saint Mleux’s ring continues to sparkle across social feeds, one thing’s for sure: this engagement is more than just a love story, it’s a moment in modern bridal fashion history. With its effortless glamour and impeccable design, it’s setting the tone for a new era of engagement rings defined not by extravagance, but by elegant individuality.
Because in the race for love and luxury, Alexandra Saint Mleux is already in pole position.
