The diamonds produced using this method are minuscule, hundreds of thousands of times smaller than those grown with the HPHT method. Hence, these diamonds are far too small for jewelry applications.
Ah, there’s the catch.
Not a catch, majority of diamonds are used in industries and need to be small.
It’s a catch when your perspective is hoping it will impact the negatives of the jewelry industry.
Will never happen until De beers exits the stage or is forced to.
We already have incredibly easy to make and cheap diamonds that can rival and surpass any natural sized ones.
They do not sell nearly as well because De beers has convinced everyone natural diamonds are a scarce resource, while they have a monopoly on the supply, of which there is no actual scarcity.

What’s the biggest synthetic diamond we’ve made so far? Has anyone made diamond spectacles or windows?
They’re quite brittle, so probably not a window like you’re thinking.

Ah, so still not quite Cullinan-scale yet. Optical quality is probably better though.
I’m surprised diamonds aren’t used more for lenses. Given its high index of refraction, it seems like an ideal material.
Yeah, the optical quality seems to be the main point. I assume there’s few fields where that level of precision is worth it though. I doubt we’re about to see it on an iPhone any time soon.
The problem wouldn’t be fixed even then. The jewelery companies have people convinced that the only diamonds that are worth it are mined from the earth by a real human slave. Fixing that problem has nothing to do with gemstones.

Is this still the case? I feel like I’ve seen “conflict free” as a selling point for (presumably labgrown) diamonds.
Me too. I’ve also heard synthetic gemstones can have colours and structures unlike anything that can form naturally. I want one of those, so that nobody would mistake it for a mined stone.
They should really start with this
For now. But diamonds are used for much more than simply jewelry. They have a vast number of industrial applications.
They do mention that. Likely have applications in industrial drilling and sandpaper
Shoe soles.
Really? That’s pretty cool.
No, see my comment above. It’s a reference to a Paul Simon song, “Diamonds on the soles of her shoes”. While they might make the shoe soles last longer, they would be abrasive to flooring materials, and so not really practical at any price.
Ah thanks for the clarification. What was the point (ha!) of the shoes in the song? Surely it wasn’t just scratching floors?
The song is a rich girl/ poor boy love song with some significant political commentary, made more palatable by the catchy tune. The rich girl is so wealthy she could afford to have diamonds on her shoe soles. This was released on Graceland in 1986. Diamonds were/are mined in South Africa - dug from the ground by poor South Africans. The whole story about DeBoers controlling the supply and price of diamonds may not have broken at that point. And even to this day we can’t synthesize large ‘jewelry’ grade diamonds.
Dang, and I was thinking it was time to put ‘diamonds on the soles of my shoes.’
Calm down Paul
Slip out the back, Jack
Get a new plan, Stan
Fuck off, Geoff
Keep an eye on your kidney, Sydney.
Diamond industry is just a scam, see the documentary " Nothing lasts forever ".
Just a thought, but could these tiny diamonds be used to coat the surface of car tires to lower the amount of micro plastics they emit?
The softer material will be chewed to pieces by the harder one. How much are you willing to spend on road maintenance?
Just cover the road in diamonds, easy. Or, as a more realistic approach, enhance railway infrastructure to minimise the need for cars.
I keep saying it, big, orange, hot wheels tracks.
Rail transport is the way to go. Hands down, my favorite way to travel.
