Taylor Swift’s Perfectly Flawed Diamond

Taylor Swift’s engagement to Travis Kelce tells you everything you need to know about the diamond business.

And the timing couldn’t have been better for an industry that’s endured a particularly Cruel Summer — demand Down Bad, stuck in Don’t Blame Me mode, and struggling to Shake It Off. (Yes, those are song titles — forgive me, I don’t often get the chance to unleash my inner Swiftie).

And already, the announcement has given the industry a massive boost — far bigger than your average celebrity engagement.

Swift shared the news with her 282 million Instagram followers in a carousel of photos, one of which zoomed in on the unusual choice of diamond: an antique (old mine), elongated cushion-cut stone, estimated at 8 to 10 carats, set on a yellow-gold band.

The internet went into a diamond frenzy. Google Trends lit up with spikes in searches for terms like “diamond engagement ring,” “old mine diamond,” “cushion cut diamond,” while “old mine cut” exploded.

Looked at simply, these trends point to the gradual shift in consumer taste toward unique, antique-style stones and settings — something the trade can lean into, especially heading into the holiday season.

But there’s more going on beneath the surface. Credit here goes to Max Rosenblum, an industry outsider, and self-described armchair economic journalist, whose video The Economic Impact of Taylor Swift’s Engagement is the sharpest take I’ve seen on what this ring really means.

Max tries to unpack why shares of Signet Jewelers rose on the engagement news, while those of Brilliant Earth jumped 28%. He points to a seismic shift in consumer preferences that the couple’s choice of ring represents, calling it “a strategic masterstroke in the diamond industry’s proxy war against its own existential threat: lab-grown diamonds.”

If only it were that intentional, right?

Still, his explanation was so profound I almost want us to take credit for it. At the very least, it deserves to be documented verbatim:

“The lab-grown market has achieved near-perfect commoditization, offering flawless clarity and color at a fraction of the cost. In other words, they've weaponized perfection. And the natural diamond industry can't compete on price or flawlessness, so it's pivoted to selling the one thing a lab can't replicate: history. And the couple's choice of an antique hand-cut, centuries-old natural stone isn't just a preference; it's the ultimate market differentiator. Because it reframes value away from sterile perfection and toward character, provenance, and the romance of a one-of-one asset.”

The sterile perfection of a lab-grown diamond has no match for the rich story a natural diamond can tell. Where the D-Flawless once held the highest value — and still does in the natural diamond market given its real scarcity — synthetics have made them so common that it’s the quirks and flaws in Taylor’s stone that now stand out as the truly valuable feature.

It’s a poetic twist — one that mirrors the challenges we face with automation, artificial intelligence, the relentless news cycle, and the noisy, presumptuous world of social media. In that sense, synthetics are the diamond equivalent of all that noise — flawless on the surface, but predictable and forgettable. At the end of the day, humans need realness and crave authenticity. We're able to recognize ourselves through our flaws.

The irony, of course, is that both Signet and Brilliant Earth have embraced lab-grown as part of their growth strategies. Their respective share price pops may have reflected a short-term celebrity effect more than a structural shift. But the symbolism of Swift’s diamond highlights the tension at the heart of the industry: investors reward volume and accessibility, while long-term value lies in scarcity, story, and differentiation.

This time, as Max adds, it came through an “unintentional targeted campaign against the perceived soullessness of its synthetic competitors, executed by the world’s most influential consumer.” It was a welcome windfall. Now, it's up to the industry to pick up her refrain.
