Everything to Know About Lauren Sánchez’s 30-Carat Ring

Everything to Know About Lauren Sánchez’s 30-Carat Ring

Lauren Sánchez’s engagement ring from Jeff Bezos is a rare sight. Jewelry insiders and auction experts agree that the size and color make it one of the few stones of its kind seen in public hands. As GoodStone, we have spent years studying the stones that attract headlines and collectors. Here is what makes this ring so noteworthy, backed up by data pulled from industry experts, publications, and real public sightings.

The Diamond at the Center: 30 Carats of Pink Rarity

The ring’s center is a cushion-cut diamond. It weighs about 30 carats. The measurements come in at about 19.50 by 15.40 millimeters. It takes up most of the finger.

It is held in place with four strong platinum prongs. Each side has a round diamond, about 2 millimeters across. The color, though, is what places this diamond in a class that only a handful of stones ever reach. It is a vivid pink. Gem labs and auction houses mark pink as one of the rarest diamond hues on the market. Most diamonds never show any strong color ,  the few that do tend to be yellow or brown, not a deep, even pink.

Pink diamonds over five carats are not common. A 30-carat pink diamond in a cushion cut is close to unique. Most connoisseurs will never see a stone like this in person. Several jewelers confirmed this to ELLE in June 2025, with one expert stating that so far this decade, “almost no” diamonds approaching this color, size, and clarity have entered the public market. So when Lauren Sánchez appears with this ring in public, it is a rare real-world chance to see a stone at this level.

Why Pink Diamonds Command Such a Premium

Not all pink diamonds are the same. Stones are graded for hue, strength of color, and evenness. Pale or patchy pinks drop in price. The Sánchez stone’s color appears strong and saturated. Experts say pink diamonds at this size and color fetch a premium that outpaces white diamonds at similar weights. Cushion cut is a common choice for pink diamonds because, when done well, it strengthens the color and lets more light enter the stone. At this size, getting the cut right means the diamond keeps ‘life’ and doesn’t turn dull or “glassy”.

Most pink diamonds in recent auctions have come from one source: the Argyle mine in Australia. That mine is now closed. Every pink stone from Argyle is now in private hands or a vault, and nothing will replace them. The mine’s shutdown has increased pressure on the value and rarity of pink stones of any size.

Build and Setting

The ring uses a classic four-prong setting in platinum. This is about security first. A 30-carat diamond is heavy. If the band is too thin or the prongs are weak, you risk the stone bending or breaking its setting. The prongs in Sánchez’s ring are angled to hold each corner tightly. The platinum band is thick, almost chunky. It needs this extra weight to stay upright and make sure the diamond isn’t sliding from side to side on the finger.

The side diamonds are subtle compared to the center stone, but they matter for balance. When a ring tips forward or back due to weight, it can be uncomfortable. Side stones, weighted evenly, help keep the top-heavy diamond from pulling down.

Crafting a Ring at This Level

Making a ring for a 30-carat diamond isn’t easy. Jewelers must custom-build the setting. The fit must be exact. If the prongs are even a little loose, the diamond could wobble or, worse, fall out. Every angle and every connection point is checked and adjusted until secure. But overbuilding it would make the ring look bulky. The challenge is to keep the diamond safe while giving it a neat, understated structure.

Some jewelers compare this work to building a tiny sculpture. Each part needs to hold weight and survive years of wear. That calls for careful tests, measured risk, and skill.

Value: How Much Is It Worth?

Most jewelers who spoke to PEOPLE, InStyle, and ELLE place the value in the $3 million to $5 million range. There is no public record of the final price, but this estimate considers carat weight, color, cut, and the global market for pink diamonds. The price could be higher depending on exact clarity and provenance.

Here’s a look at the main factors:

Carat Weight: Each step up raises the price by more than the last. Thirty carats are outside normal grading charts.

Color Intensity: An even, saturated pink is at the very top of the rarity scale.

Cut Quality: Cushion cut brings out the color’s depth. If the stone were poorly cut, even with good color, the price would drop.

Provenance: The origin can increase worth, especially if it is traceable to a closed source like Argyle. This hasn’t been made public for the Sánchez diamond.

Most pink diamonds at auction aren’t anywhere near this weight. One of the few to compare is the “Pink Star,” a 59.6-carat stone, which sold for $71 million. That was a record sale and is still talked about in jewelry circles.

Against Other Famous Rings

Sánchez’s ring is often compared to other engagement rings from famous couples:

Kim Kardashian: 15-carat cushion-cut diamond, $2 million.

Mariah Carey: 35-carat emerald-cut white diamond, about $10 million.

Jennifer Lopez: 8.5-carat pink diamond, over $2 million.

Beyoncé: 18-carat white diamond, about $5 million.

Sánchez’s ring is at the very top for carat weight and is the only one with a vivid pink at this level.

Where the Diamond Came From

There’s been no verified information about which jeweler sourced or cut the diamond. No one has come forward to claim authorship, and the couple has chosen to keep details private so far. That adds to the sense of rarity, with no shop or brand using the ring for wider publicity.

Pink diamonds like this tend to be traded quietly, often among collectors and investors, which may explain the secrecy. Auction houses such as Sotheby’s and Christie’s often handle similar stones, but none have claimed this ring as a previous sale.

Public Sightings: Where the Ring Shows Up

Lauren Sánchez wears the ring on special occasions. She has been seen with it at red-carpet events, formal parties, and in lifestyle portraits for magazines like Vogue and ELLE. The ring attracts attention as soon as she lifts a hand.

At her Venice ceremony in June 2025, Sánchez chose not to wear the engagement ring. She wore only a plain wedding band during the ceremony, then brought the pink diamond back for photos and later events. This choice seems to be about comfort and tradition rather than not wanting the spotlight on the ring. In the published photos, the ring is featured with her wedding band.

The Proposal

Sánchez spoke briefly to Vogue in November 2023 about the proposal itself. Bezos chose a private moment, putting the ring under her pillow on his yacht during a trip. Sánchez said, “When he opened the box, I think I blacked out a bit,” and called the moment “a total fairytale.” She said her partnership with Bezos is about being a team and sharing everything.

What Experts Say

Industry voices see the Sánchez engagement ring as one of the only modern stones that could sit next to auction-block legends like the “Pink Star” or the “Winston Pink Legacy” (an 18.96-carat vivid pink that sold for $50 million). Few experts have seen a stone of this size, color, and clarity outside of museum or state collections. Jewelers noted to ELLE that producing a 30-carat pink diamond with this clarity and cut takes years of work, a lucky find, and careful handling at every stage.

Setting the diamond was another area of expert focus. Keeping saturation while shaping a cushion cut at this size, then building a mounting strong enough to hold it, requires careful planning. Jewelers told InStyle the finished ring was “flawless”.

What a Ring Like This Means for Jewelry Trends

White diamonds are still the standard for most engagement rings, but pink diamonds at this level draw attention from collectors and those looking for a once-in-a-lifetime gift. At GoodStone, we get inquiries about creating rings inspired by these rare pieces. Many choose lab-grown pink diamonds because the natural versions are so hard to source. Some opt for colored sapphires or custom settings that mimic the cushion-cut silhouette and platinum band.

We build each piece to match the exact taste and comfort level of the client, using thick platinum bands, strong prongs, and hand-picked center stones. Most customer requests focus on bringing a sense of the original’s rarity into a ring they can wear daily, not keep locked away.
