Yes, Paris Jackson's engagement ring is lab-grown. It's a roughly 3-carat portrait-cut diamond set in 18k yellow gold with a halo of pave accent stones, designed by Jean Dousset (the same designer behind Paris Hilton's ring, and the great-great-grandson of Louis Cartier). Justin Long proposed sometime before the couple confirmed their engagement in late 2024, and the ring drew attention for two reasons: the cut is rare, and the stone didn't come out of the ground. That second detail matters more than most of the coverage gave it credit for. According to The Knot's 2025 Real Weddings Study, 52% of couples married in 2024 chose a lab-grown diamond for their engagement ring, up from just 12% in 2019. Jackson's ring didn't start that shift. It's a clean, well-documented snapshot of where the shift landed.
Is Paris Jackson's Engagement Ring Really Lab-Grown?
It is, and it's documented well enough that I don't need to hedge on this one. Jean Dousset posted the design details himself, and outlets that actually called the designer's studio (not just the ones that ran with a caption) confirmed the stone is lab-grown. You can read Dousset's own account of the piece on his site, and see the original reveal on Instagram.
Here's the part worth sitting with: nobody had to spin this as a compromise. A decade ago, a lab-grown stone on a red carpet ring would have been treated as the budget option, the thing you mention quietly. Now it's the headline.
What Does the Ring Actually Look Like? (Correcting the Record)
A few blogs have gotten this wrong, so let's fix it. One widely shared post describes an 8-carat stone in rose gold with a bezel setting. That's not what's on her hand. Based on the designer's own account and reporting that actually cross-checked with his studio (Page Six, relayed in detail by InStore Magazine's Judge the Jewels column), the ring is a portrait-cut lab-grown diamond, roughly 3 carats, set in 18k yellow gold (not rose gold), finished with a halo and pave accent stones (not a bezel).
Comparable listings from Dousset's own line put a piece like this at $10,000 to $15,000, a fraction of what an equivalent mined stone in this rarity would run. The portrait cut itself is a deliberate choice, not a default: an old cut style, originally used so a thin, flat diamond could sit over a miniature painted portrait without blocking it. Halo and pave settings like this one add perceived size and sparkle around a center stone chosen for shape over brute brilliance.
Why Did Justin Long and Jean Dousset Choose a Lab-Grown Diamond?
Neither Jackson nor Long has explained the decision publicly, and I won't pretend to know what was said in that meeting. What we do know: Jackson has spent years attached to sustainability-minded brands, and a custom lab-grown stone lets a designer like Dousset build a large, rare-cut diamond without the sourcing headaches (or price tag) of finding a natural stone in that shape and size. Portrait cuts are already uncommon in mined diamonds, since rough crystals rarely split into that flat, elongated shape without a lot of waste. Lab-grown material sidesteps that problem. You grow the crystal to the shape you want to cut, instead of hoping nature cooperates.
That's why unusual cuts (portrait, elongated cushion, antique-inspired shapes) are becoming realistic custom requests instead of six-figure novelties.
Is This Really Lab-Grown's "Biggest Celebrity Moment"? (The 52% Question)
I'll make the case, then argue with myself a little, because the honest answer isn't a straight line.
The case for "biggest moment yet": CNBC reported on The Knot's 2025 Real Weddings Study, which surveyed roughly 17,000 couples married in 2024. Fifty-two percent chose a lab-grown diamond, up from 46% in 2023 and just 12% in 2019. Average total ring spend also dropped, from about $7,600 for a mined stone to around $4,900 for lab-grown, while average carat weight purchased climbed from 1.5 to 1.7 carats. Buyers aren't settling for less. They're buying more diamond for less money. Fortune's coverage of a McKinsey study puts it plainly: adoption among Gen Z and millennial couples has gone well beyond what the mining industry expected. Axios has tracked the same pattern from the cost side. Against that backdrop, a public figure with a large diamond and no apology attached to it reads as confirmation, not novelty.
Now the counterpoint. JCK reported that wholesale lab-grown prices have dropped 90 to 95% since 2015, and some retailers are souring on the category as margins (once 80 to 90%) compress fast. Analyst Paul Zimnisky predicts lab-grown stones eventually become a $200 impulse buy, not a $20,000 investment piece. If that plays out, a five-figure portrait-cut lab diamond might look unusual in five years, not because lab-grown loses appeal, but because it gets cheaper, not rarer. I don't think that undermines the "big moment" framing. It just means we're closer to the middle of the story than the end of it.
What's the Story Behind the Number 7?
According to Page Six's original reporting (again relayed by InStore), Long asked Dousset to work hidden references to the number 7 into the design, a number with personal meaning to the couple. Neither party has detailed exactly where those references live in the ring, and I'd rather not guess at specifics that haven't been confirmed.
What I will say: this kind of built-in symbolism is one of the real advantages of working with a custom designer instead of buying off a shelf. It's also something I'd encourage more couples to ask for, even on a modest budget. A hidden detail (a stone count, an engraving inside the band, a shape choice with a private meaning) costs very little to add and means more over time than most of the visible upgrades people pay for. If that's a direction you're considering, we've written more about designing a ring that tells your specific story, not just a generic one.
What Does This Mean If You're Ring Shopping Right Now?
If Jackson's elongated silhouette has you rethinking the standard round brilliant, good. Round brilliants get recommended constantly mostly because they're the easiest stone for a jeweler to sell off a tray, not because they suit everyone's hand or budget. An elongated cut in a halo or pave setting gives more visible size per dollar, the exact trade every buyer in that 52% statistic is already making.

Whatever shape you land on, ask for IGI or GIA certification on the stone itself, not just a receipt. GIA's own reporting confirms lab-grown diamonds share the same chemical and optical properties as mined stones, which is why a proper grading report matters more than the carat number on the tag.

Moissanite runs another 10 to 20% below lab-grown pricing at a similar size, worth knowing even if you choose diamond anyway.
Mined vs. Lab-Grown at This Carat Weight: Side by Side
| Factor | Mined Diamond | Lab-Grown Diamond |
|---|---|---|
| Avg. total ring spend (2024, The Knot) | $7,600 | $4,900 |
| Avg. carat weight purchased | 1.5 ct (2021 baseline) | 1.7 ct (2024) |
| Certification | GIA, AGS | GIA, IGI (distinct lab-grown reports) |
| Origin | Mined from the earth | Grown via CVD or HPHT |
| Resale consideration | Holds some secondary market value | Minimal resale value currently; buy for wear, not investment |
That resale line is where I won't sugarcoat things for a sales pitch. Lab-grown diamonds aren't an investment vehicle, and given the price trajectory JCK reported, I wouldn't bet on that changing. Buy one for the size and the ethics at a fair price today, not because you expect to sell it for more later.
This is the eighth post in our celebrity engagement ring series. If you missed it, we just graded Mila Kunis's engagement ring, and before that, Ciara's 16-carat cushion cut. Different budgets, different decades, same underlying question: does the ring actually fit the person wearing it.
FAQ
Is Paris Jackson's engagement ring a real diamond?
Yes. It's a real diamond, just not a mined one. Lab-grown diamonds have the same carbon crystal structure, hardness, and optical properties as mined diamonds. The only difference is where the crystal formed: a lab using CVD or HPHT technology, instead of underground pressure over a billion years.
What is a portrait-cut diamond, exactly?
A portrait cut is a flat, elongated diamond shape with minimal faceting, originally cut centuries ago so the stone could sit over a miniature painted portrait without hiding it. Today it's chosen for its glassy, transparent look rather than heavy sparkle, and for covering more finger for the money than a brilliant cut of the same carat weight.
How much does a ring like Paris Jackson's cost?
Based on comparable listings from the ring's designer, a similar 3-carat lab-grown portrait-cut diamond in an 18k gold setting runs somewhere between $10,000 and $15,000. A moissanite version of the same look typically runs 60 to 80% less.
Are lab-grown diamonds "real" diamonds, or something else?
They're real diamonds. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds, both are pure carbon crystallized in the same structure. Moissanite, by contrast, is a different mineral (silicon carbide) that looks similar but isn't a diamond at all.
Why did Paris Jackson and Justin Long choose a lab-grown diamond?
Neither has spoken publicly about the specific decision, but Jackson has a long, public track record with sustainable and ethical brands, and lab-grown diamonds avoid the mining footprint of natural stones while costing significantly less for the same size and quality.
What does the number 7 symbolize in Paris Jackson's ring?
According to Page Six, designer Jean Dousset worked hidden references to the number 7 into the ring's design at Justin Long's request, since the number holds personal significance for the couple. Dousset hasn't detailed exactly where those references sit in the design.
