The article shows the diamonds are around 200nm in size.
While not enough for jewelry, this is great for industrial applications, like abrasive grinding wheels or diamond tipped saw blades

Trying to size that: That's 0.2 micrometers. Fine sand is 75 micrometers to 425 micrometers.
(1000 micrometers = 1 millimeter)
This just tells me that diamonds are even more worthless.
Folks like de beers hoard diamonds and jack up prices to make folks think they are more rare that what they really are. We gotta stop the cycle and buy lab grown or use an entirely different stone all together. Diamonds are for basic bitches anyhow
Vintage sapphire is where it's at. Nothing comes close to the magic blue of untreated sapphire.

Recommend looking into moissanite also if you like diamonds but don't want to support the industry. Very similar looking, better in some ways. And because it hardly occurs naturally at all, you can only buy synthetic.

They always were -- outside of engineering of course.

These diamonds are too tiny for jewelry but I don't care.
I want a diamond heat spreader for my CPU!

You already can.
Go bling up your heat spreading
Everywhere I'm looking says sold out unfortunately. I've been using Arctic Silver for over a decade with no issue though, but I'm curious.

One problem is that the diamonds grown with this technique are tiny
So the next we need is a way to shrink the women so that they fit.
Everyone always thinks the jewelry when they think of diamonds but I am excited for the prospects of what cheap lab-grown diamonds can do for manufacturing. Diamonds are electrically insulative and yet 10 times more thermally conductive than copper. There are a LOT of industries that would be VERY interested in that.
Hell, it would probably be useful in CPU substrate as well. Instead of silicon semi conductor doping if these could be made precisely enough you could use diamond for the insulation layers and gain that insane heat transfer efficiency to help with avoiding Hotspots. Maybe that's too thin to matter that much not sure
Heavily used in the building industry too. Concrete saws, tile cutters etc, all expensive as fuck
Diamonds are the hardest mineral known to humans, it's what we use for all deep sea drilling and excavation.

The picture is a bit misleading, they are super tiny! Very cool thought.
Looking forward to a future when fake rhinestones are just kinda shit manufactured diamonds.
Super tiny is fine for the things diamonds are used for besides sparkling on fingers.
So you're saying I could get a diamond tip nozzle for my desktop 3d printer?
You can already, and for quite some time. They claim to be superior to all others.
I have a tungsten steel nozzle on mine and it's been good for a long time, I imagine it'll run forever. Does anybody have experience with the diamond ones? Are they worth the extra expense?
I haven't tried them myself but they have (at least in theory) a lot of benefits speaking for them.
You won't wear them out, no matter how abrasive your filament is. At least until you print diamonds I guess.
Diamond conducts heat so much better than any other material you might make nozzles from it's hard to believe. You might (or will) run your prints way cooler, or faster.
Several other things I won't explain here because I have no idea and would have to make them up on the spot. But how cool would it be to print with a poly crystalline diamond nozzle? I bet you'd drown in panties.
Which could be a drawback.
Looking into it, these are very fragile nozzles. Even more so than the ruby ones. The Tungsten nozzles are the true robust nozzle. It will wear out if you're using filament with abrasive materials but it takes a lot to do it. I'm going to keep it in mind but probably won't consider it
Similar conditions are employed in the method currently used to synthesize 99% of all artificially created diamonds. Called high-pressure and high-temperature (HPHT) growth, this method uses these extreme settings to coax carbon dissolved in liquid metals, like iron, to convert it to diamond around a small seed, or starter diamond.
Cool. I don't know how expensive this process is right now, but it seems cheaper to do, at least on mass production.
Edit: I wonder if they could make a tether out of this thing.
“Bender, be careful! Thats the ship’s diamond filament tether. It’s unbreakable!”
“Then why do I have to be careful?”
“It belonged to my grandmother.”

Looks like the diamond industry just wrote a new hit list
However, the new method has its own challenges. One problem is that the diamonds grown with this technique are tiny; the largest ones are hundreds of thousands of times smaller than the ones grown with HPHT. That makes them too small to be used as jewels.
Not going to be wearing these any time soon
Just wear hundreds of thousands of them glued together, problem solved.
On a more realistic note though, the applications of this will probably be industrial for a good while. I found it interesting how the article mentions that they were able to develop a diamond coating over their growth substrate. That probably has some cool applications in industrial settings where diamond-plated materials are used.
Diamond saw blades are about to get cheaper
Not in a profit driven economy...
It depends; if a company can use this to make them stupid cheap, then selling them stupid cheap to undercut all their competitors could still make them more money than keeping the price the same and pocketing the saved production costs.
I was making a jab. I'm aware of market forces, but price memory is a thing and often the true cost of production isn't reflected in consumer pricing. Especially when an industry just decides they can keep prices where they are if not raise them, looking at you egg producers.
Not useful for jewelry, but possibly quite useful for many manufacturing or industrial purposes?
So... useful then?

Do we really want to use the word “groundbreaking” to describe advances in synthetic minerals?
Dad?
Hey hey hey, don't break the ground. Are they insane?
they are small, but the large diamonds are made from seeds, so still can be used for that, or techniques can improve for larger size production in the future, also, small diamonds are useful for cutting machines
DeBeers says wtf
Either JPL or LM (I can't remember which) was working on a HTHP system with the goal of being able to grow diamonds with ICs built in. I wonder if this has that potential.
Whut?
Defense contractors want to grow diamond computer processors. Because silicon breaks down at high temperatures.
