Jennifer Lopez's 74-Carat Paraíba Tourmaline Necklace Just Stole Milan Fashion Week

One Spin, and the Whole Room Looked at Her Neck

On Wednesday night at Vogue World: Milano — the glittering event that opened Milan Fashion Week inside the Galleria Vittorio Emanuele II — Jennifer Lopez did what J.Lo does best: she stole the show. Pulled from the front row to the center of the arcade, she danced and spun in front of the crowd, and every camera in the building followed the light bouncing off her neck.

The source of that glow was a Dolce & Gabbana Alta Gioielleria necklace built around a single, almost unreal 74.459-carat Paraíba tourmaline — a neon blue-green gemstone set in white gold and surrounded by hundreds of diamonds. Lopez wore it just above the neckline of a black corset-tulle Dolce & Gabbana gown, finished with sheer opera gloves, slingback pumps, and matching white-gold-and-diamond earrings and ring.

What She Was Actually Wearing

This was not a diamond rivière or a familiar emerald suite. The centerpiece belongs to one of the rarest categories in all of gemology, and the specifics are worth slowing down for.

To put 74 carats in perspective: fine Paraíba crystals are so scarce that a stone over two or three carats is already considered an extreme rarity, and prices per carat climb exponentially past the five-carat mark. A single, clean, richly saturated stone north of 70 carats is the kind of gem that gets a name and a case of its own.

The Princess Diana Connection Nobody Expected

Here's the detail that pushed this from a fashion-week photo into a story everyone's sharing: the exact same Dolce & Gabbana necklace was worn last October by Lady Kitty Spencer — model, aristocrat, and the niece of the late Princess Diana — when she accepted an award for the house's jewelry line at the Grand Prix de la Haute Joaillerie.

It's a quiet reminder of how the top of the high-jewelry world actually works: the truly exceptional stones circulate among a tiny orbit of muses, maisons, and collectors, appearing in public only a handful of times.

What Exactly Is a Paraíba Tourmaline?

Discovered in 1989 in the Brazilian state of Paraíba, this tourmaline shocked the gem world with a color no one had seen before: a glowing, almost electric neon blue-to-green that seems to light up from the inside. The secret is copper (and often manganese) inside the crystal — a chemistry so unusual that for years, no other deposit on Earth could match it. Later finds in Mozambique and Nigeria added supply, but top "Paraíba-type" material remains staggeringly rare.

That "1 in 10,000" figure is the one that stops people: for roughly every ten thousand diamonds pulled from the earth, only one Paraíba tourmaline is found. It's why jewelers and collectors treat fine Paraíba as one of the most coveted colored stones in the world — and why a 74-carat example is genuinely jaw-dropping.

Why This Necklace Matters Beyond the Red Carpet

J.Lo's moment lands squarely in a trend we've been tracking all year: color is winning. Across the 2026 award-show and fashion-week circuit, A-listers have leaned into saturated colored gemstones — sapphires, emeralds, rubies, and now neon Paraíba — instead of the default white-diamond look that ruled red carpets for decades. A stone with this much personality, worn this confidently, is exactly where the taste is heading.

What does a stone like this translate to for a collector? Fine Paraíba commonly sells from about $1,000 to $35,000 per carat, with exceptional Brazilian material exceeding $50,000 per carat. Even at conservative numbers, a clean 74-carat center stone represents a seven-figure gem before a single diamond or gram of gold is added — which is why a piece like this circulates at the very top of the market.

You Don't Need a Fashion-Week Ticket for This Glow

The beauty of Paraíba is that its magic scales down beautifully. A neon Paraíba in a ring or pendant delivers the same electric color that lit up the Galleria — in a piece you can actually wear. At Forever Rox, our tourmaline collection includes genuine Paraíba pieces, from bezel-set cushions to statement cocktail rings, and we can source exceptional stones for clients chasing something truly rare.
