I am pretty involved in the gem world and I would recommend people to wait another 5-10 years before buying a lab grown diamond. When they first became big, like early 2010s, they were $3400/ct for decent quality (natural diamond of the same quality about $6-7,000) you can get that same 1ct stone for about $1200-1500 today. The prices have come down most steeply in the last 5 years, I think they will become dirt cheap sooner than later, probably
No point in mining if no one's buying them De Beers failed to brain wash the newer generation and they killed their own product by making people think that you should only buy new. Makes them worthless as soon as they leave the jewelry store
@@Lazerecho...that, and despite only earning a laughably tiny fraction- because external factors and danger still make it a relatively well paid job locally, if you don't have alternatives.
The irony is that high quality mined diamonds aren't actually that rare but the diamond houses like DeBeers deliberately restrict the supply. Combine that with the incredible skill needed to polish high quality gemstone and that's why they're still expensive.
Artificial diamonds have been produced since the 1906... The same technology today is being used to make indestructible diamond encrusted bi-layer graphene superconductors... F-diamane.

I want one of the diamond cubes for my desk. Ideally about twice that size. No interest in them cut, but just a nice cube of diamond would be nice to have.

I had the same thought! Maybe a good market for any "seconds"?
For thinner slices, google "diamond optical window". This process actually uses such windows to transmit the microwaves into the growth chamber. I'm still waiting for one other application, a heat sink interface compound, you know, like heat sink grease or strips that are near the same thermal efficiency as the diamonds for heat sinks. Once the right compound is found and affordable, I suspect we'll start seeing diamond CPU's and GPU's hit the market.
Diamond is used for the window through which plasma heating energy is injected into fusion reactors like ITER. This is because diamond is incredibly transparent over a huge range of frequencies, and the thermal conductivity is required to for cooling. They're also used for windows in other vacuum applications, of course, but pushing tens of megawatts through a 180mm diameter, 2mm thickness diamond window has to be the most amazing one. of course, these diamonds are polycrystalline, but still transparent. There's also a company making 100mm wafers of monocrystalline diamonds using a unique technology where the diamond isn't grown on a seed crystal, but on a Ir/YSZ/Si wafer. AuDiaTech in Germany. Supposedly the largest monocrystalline diamonds in the world.
Whilst not Diamond, the windows on the SR-71 Blackbird were made of 1.25 inch thick clear Quartz slabs, this was to resist the extreme heat and pressure of going mach 3+ Just a history tid bit I thought I'd add.
the problem with these types of processes is the steel being used for the chamber they're made it can erode if you use the wrong kind then while crystals are growing BOOM it finally decides to open a crack and your neighbor gets hit with a chunk of pipe going 80mph
As a material sciencentist seeing a video from you being released is always a good day :) Especially because I am working at pacvd and pvd Now it is required for me to watch this video to the end! 😅
@@Charles-Darwin Well, I personally don't use AI at work, but a colleague does use it to analyze effects for Raman spectroscopy and is quite happy with it. What I am doing is more about creating new kinds of coatings that are electrically conductive, which is quite interesting.
It is VERY hard to get anything transparent, but it would be interesting to see if they can at least get some polycrystalline stuff without graphite all through it.
@@samheasmanwhite from my recollection, it comes down to gas flow being uniform and keeping the plasma uniform, any turbulence and one starts getting defects.
Years ago there was talk of using diamond for semiconductors directly, which was supposed to allow for chips running at 10GHz and very hot temperatures with no ill effect.
Your channel is a gem, pun intended. Every time I watch one of your videos, I get a glimpse of what the tech industry is doing or has been doing. You do such a good job at presenting information. When you brought up the heat dissipation application of CVD diamonds and mentioned Synopsis buying Ansys for heat transfer simulations, it kinda blew my mind to see a connection like that. Not a surprising connection, but one I didn’t think about until you mentioned it.
Indeed diamonds have a bright future a head of them. Next to all of the other stories in the comments, Some time ago it was found how to make a P-fet on diamond filament, and recently also the N-fet. thus making it possible to make full IC's in diamond filament.
Didn't hear of the N-FET. Yeah, that paves the way, assuming the defect rate can be lowered enough to make the things affordable. Looks like Moore's Law is back in business!
The fact that people would want to have “natural” diamonds instead of “synthetic”, if optical, mechanical, and other physical properties are essentially equivalent, is just ridiculous
people don't care, look at perls, the diamond mining monopoly is the one complaing, they know they gonna lose, they're trying to shift the people vision that lab grown diamonds are inferiors, that why they complained, when FTC removed that requiriment, now they can't use that to shift public opinion, they are losing
Hey dude. I love your channel and it’s absolute science. Respect. Keep being you(making science videos) and I will keep being happy(watching your science videos) as a man can possibly be. Respect
There was a cool article by Wired in 2003 called The New Diamond Age that talked about CVD diamonds and the possible future of "diamond semiconducting"
Diamond has also popped up for the quantum computing community. As mentioned there can be nitrogen defects introduced. Nitrogen vacancy defects in the diamond have come out as a means for qubit generation
People like diamonds. What is absurd about that? Or are you going to next say that it is absurd that people buy gold for non-industrial purposes as well? These things are market-dictated. People pay as much as something is worth to them. Although, in the case of diamonds, as he alluded to, De Beers holds a near monopoly, and can thus artificially manipulate the price. But, they can only do so much; there still has to be a market.
So youve never bought anything just to show it off? Not a tshirt with a band logo on it, some nerdy computer shit, nothing? If you have, you should be able to understand why people buy jewelry. Anyway stop being a loser
Crazy you mentioned heat spreaders, that is what the CVD machine was originally used for, literally to wick the heat away from stacked laser bar arrays used in welders and higher power DPSSLs. We eventually did runs of DUV phodiodes with it.❤
As a jeweler thats a amazing, a lot of tools needs diamonds to cut and polish, but eventually lab diamonds will be just like glass, and the natural ones will probably be mutch more expensive because mining will not be viable anymore, the cool thing is that other gems will get more visibility, personally, clear diamonds are kinda boring.
At which point the value is pfft. The original value was in the scarcity and difficulty in obtaining them. All this has done (aside from the industrial benefits) is dilute the value of every other diamond on the planet, each time one is created. If you just like them for the look, that's fine, it's not like there's something wrong with wanting or owning the stones... just remember the numbers seen at the counters are artificially higher and only more so as time goes on as a result of this "ability".
For me, as nerd, grown diamond is even better thing! "look honey! Our technical culture made this possible! Nanometers in smartwatch, diamonds in ring" ;D
A few days ago I saw an article about making diamonds at ordinary pressure and reduced temperature in liquid metal. They are still experimenting though.
I think there is already an exclusive application for CVD diamonds in anything that needs to be very wide, like 20mm or more. Can't get the thickness but you can get the width. Very difficult and expensive though, so that market won't carry CVD on it's own without some common technology that needs and can afford wide diamond windows or such.
How are the diamond wafer pre cursors made? Is it possible to buy the unprocessed diamond cubes? They would make an interesting industrial curiosity without the distraction of being formed into jewelry.
In most cases, a diamond engagement ring or other diamond jewelry will have a resale value of between 20 and 60% of the amount it cost when it was new.
That sounds good in theory for scratch resistance, but my brain immediately throws up other concerns. sapphire glass is already a thing, and I'm not sure about the actual durability of a diamond thin enough to be a screen over a digitizer. I also don't know how the conductivity of a diamond would interact with the capacitance.
It's called money laundering, so your corporation can add value without making a profit, in effect declare a loss. Think about it. Completely legal too.
I believe he is referring to the Synopsys agreement to acquire ANSYS here, but I could be mistaken in that. That deal still hasn’t completed due to navigating regulatory hurdles (anti-trust things is what my understanding is). ANSYS has lots more software to offer, but Synopsys probably is primarily interested in just that one piece.
Observe the classic marketing pivot from "natural = pure, you can't do it like nature does" to "natural = impure, and the impurities are what makes the thing unique" once technology catches up.
Im more interested in getting some of the off cuts, or flawed cubes to some electrical testing with. I wish though that i had the appropriate skills to use onenofbthose deposition machines. Might be nice to work with a micron to micron layers or wafers.
Personally I'm not into bling at all, but if I were I'd much rather have a grown diamond, since I know it wasn't be mined at gunpoint in miserable conditions in one of Wagner Groups "protected" diamond mines somewhere in Africa.

If you like commercial microwaves being dissected for development tools you may not be aware how strained silicon divices were tested. Stick a small spacer under one side of a wafer and press down and observe the device speed and Vt’s
@@fredfred2363 it is surprising how much you can test with such simplicity. Obviously straining silicon for production took orders of magnitude more engineering, but while bringing up electroplating I was using back grind tape to ensure there wasn’t oxidation between layers. Only to find out there was a nist test with a specific model of scotch tape and adhesion pressure to do the same test. The end result was we could use my test to guarantee passing the nist tast and get zero voids after reflow instead of an ‘acceptable’ level. I’m not a degreed engineer I just apparently have an abundance of common sense apparently. I worked with a team of phd’s but was the simple solution person. You need a couple million dollars for an advanced cvd tool, I can do it with a hot plate and a blast off a liquid n2 supply. Tested with a home depot sprayer. Every manager in the building had gold foil hanging on their office wall in the shape of a wafer because I could delaminate it on demand. I also made the anniversary wafers with a uv cure tool instead of a stepper or aligner and in any color desired instead of just purple poly on silicon.

Waiting for diamond heatsinks to be sold at Mouser and Digi-Key, for only a couple of bucks each ! Wonder if that will happen before I'm staring at the ground, from the wrong side.
The grit used in those applications was mentioned in his other video on creating diamonds. The equipment and process is less complex, since impurities aren’t a big factor and since the size is intended to be tiny.
So, in a limit they could possibly make diamond that costs as low as an input carbon and power, right? I can only imagine pure diamond computer with heatsink from diamond and diamond PCBs and diamond case. Completely transparent beauty, with copper wires being only opaque parts.
A lab at a local school is growing diamond spirals using ethanol/methanol and lasers, potentially for terahertz-wave communication or whatever they want really
I heard Boris Derjaguin, mentioned here, give a talk in 1977. He was a polymath most famous for formulating the "DLVO" theory of colloidal stability during WWII with his buddy Lev Landau (see his appallingly difficult "Course in Theoretical Physics").
BROOOOOOOOOO no way you are nailing it but I haven't even finished the hard drives yet LOL Damn this is great ! haha I remember buying some stuff on eBay over 20yrs ago from a mine. Made a good amount and two of the sales were to jewellers. Colour changing stones and a ruby ring. Amazed me how cheap they were. Those days are long gone now its just a shidhole with a poor, duct taped together website, total mess. Amazon if it was on fire. And I still have some raw emerald somewhere. Nice.
I flew as a passnger in a High wing glider piloted by the brilliant GE scientist that made first commercial artificial diamond process which apparently is still used today. Great guy although the glider flight was a bit scary since the glider was winched at more then a 45 degree angle up into the air using an old car that had a large drum attached to a very old car engine that pulled us both up into the air !
Less well-known is that one of the pioneering researchers responsible for this was a woman, Judith Milledge (1927-2021). She also worked with Catherine Lonsdale of londsdalite fame, the hexagonal form of diamond.
07:25 2.45 GHz is preferable for use in microwave equipment for reasons beyond magnetron availability. You need to pass tests for radio frequency interference in every country in which you want to sell your equipment. "The frequency of 2.45 GHz is chosen because it falls in one of the bands not reserved for communication purposes." (Physics Stack Exchange) See also Wikipedia's Industrial, Scientific, and Medical (ISM) Radio Band.
What was the context of the question on Physics SE? Diamond production or why 2.45 GHz is used in general? If some other frequency was found to be orders of magnitude more effective for this purpose somehow, I'm sure you could solve the regulatory issue. Apply for a special license and/or build a giant faraday cage around the equipment. If there's a will (and money to be made) there's usually a way.
@@Gameboygenius the microwaves are just used to generate the plasma. There's no magic microwave frequency for that. Other frequencies might need a little more or less power, but avoiding the regulatory headache of using a protected frequency (there's always microwave leakage) means everbody just uses 2.45 GHz unless they really, really need something different and can really, really shield against any RF leakage.
Arguably cooler to have a manufactured diamond, anyone can just find one, manufacturing one is way more of an achievement

He didn’t specifically name ANSYS there, but I concur that this seems to be what he is getting at.
I believe he is referring to the Synopsys agreement to acquire ANSYS here, but I could be mistaken in that. That deal still hasn’t completed due to navigating regulatory hurdles (anti-trust things is what my understanding is).
ANSYS has lots more software to offer, but Synopsys probably is primarily interested in just that one piece.
I love this progress.
If you like commercial microwaves being dissected for development tools you may not be aware how strained silicon divices were tested.
Stick a small spacer under one side of a wafer and press down and observe the device speed and Vt’s
I enjoy watching the results of that experiment...
@@fredfred2363 it is surprising how much you can test with such simplicity. Obviously straining silicon for production took orders of magnitude more engineering, but while bringing up electroplating I was using back grind tape to ensure there wasn’t oxidation between layers. Only to find out there was a nist test with a specific model of scotch tape and adhesion pressure to do the same test. The end result was we could use my test to guarantee passing the nist tast and get zero voids after reflow instead of an ‘acceptable’ level.
I’m not a degreed engineer I just apparently have an abundance of common sense apparently. I worked with a team of phd’s but was the simple solution person. You need a couple million dollars for an advanced cvd tool, I can do it with a hot plate and a blast off a liquid n2 supply. Tested with a home depot sprayer. Every manager in the building had gold foil hanging on their office wall in the shape of a wafer because I could delaminate it on demand. I also made the anniversary wafers with a uv cure tool instead of a stepper or aligner and in any color desired instead of just purple poly on silicon.
9:36 This is very similar to that time when aluminum pass from the "precious" metal category to "common".
A link to the sponsor's business offering would be nice - great content!
Diamonds are the Girls best Friend. Dupdupdidu. There are a old sing with this phrase in it. First in my mind when Diamond is involved. Good Video as always! The most are totally over my head and not my Mother language, but your Voice and professional to make it easy to watch! That's are really rare in Space of Since because it's Since! Thanks for your hard work to teach a noob like me so extremely hard complex topics! Thanks 👍😎‼️
Mind blowing :D excellent as always!
You are a diamond
Correct
I don't know. I think Jon is more of a 9N purity silicon kind of guy.
I thought this video better have some plasma in it, wasn't disappointed :) Everything is better with plasma.
Given the tetravalence of both carbon and silicium could it be possible to make carbon based circuit with the deposition technology ?
I believe there is research that is seeking to do just that.
The university where I studied has a lab for growing diamonds :)
Fact: Women love diamonds for their wide range of industrial applications.
oh ya.. lasers.. you should do a presentation just on the laser use of manufactured diamonds and then on on diamonds in photo-optical circuitry
Waiting for diamond heatsinks to be sold at Mouser and Digi-Key, for only a couple of bucks each ! Wonder if that will happen before I'm staring at the ground, from the wrong side.
Don't forget the construction industry - diamond cutting disks and tile drill bits
maybe they just use the floor sweepings for these applications
The grit used in those applications was mentioned in his other video on creating diamonds. The equipment and process is less complex, since impurities aren’t a big factor and since the size is intended to be tiny.
So, in a limit they could possibly make diamond that costs as low as an input carbon and power, right? I can only imagine pure diamond computer with heatsink from diamond and diamond PCBs and diamond case. Completely transparent beauty, with copper wires being only opaque parts.
Also, I would only imagine how thin and light glass lenses can be made from diamond. And camera lens?
A lab at a local school is growing diamond spirals using ethanol/methanol and lasers, potentially for terahertz-wave communication or whatever they want really
It sounds like diamond needs to be cheap enough for use in many applications and make the world better. I hope the day would come soon.
How do you tell an artificial diamond? Its too perfect. That means the diamond mining industry is on its way out.
I hope that the mpcvd method drops the market price of diamonds into the 20$per carat range for jewelry grade diamonds. Put debeers into recievership!
Great, so now we can put Diamonds on our GPUs to bling them out and to also act as heat sinks?? They would really go well with RGB.
I heard Boris Derjaguin, mentioned here, give a talk in 1977. He was a polymath most famous for formulating the "DLVO" theory of colloidal stability during WWII with his buddy Lev Landau (see his appallingly difficult "Course in Theoretical Physics").
Vanity, Vanity , Vanity .
Did you make this video on news of Anglo American offloading De Beers ?😊
how are the diamond seeds made?
a sufficiently tall diamond square but cut diagonally?
Just to clarify my doubt , the substrate maintained at high temperature is the same diamond seed thing that entered the reactor.Right?
BROOOOOOOOOO no way you are nailing it but I haven't even finished the hard drives yet LOL
Damn this is great ! haha I remember buying some stuff on eBay over 20yrs ago from a mine. Made a good amount and two of the sales were to jewellers. Colour changing stones and a ruby ring. Amazed me how cheap they were. Those days are long gone now its just a shidhole with a poor, duct taped together website, total mess. Amazon if it was on fire.
And I still have some raw emerald somewhere. Nice.
Odd, but I want a Diamond block. Can you buy them?
I flew as a passnger in a High wing glider piloted by the brilliant GE scientist that made first commercial artificial diamond process which apparently is still used today. Great guy although the glider flight was a bit scary since the glider was winched at more then a 45 degree angle up into the air using an old car that had a large drum attached to a very old car engine that pulled us both up into the air !
Less well-known is that one of the pioneering researchers responsible for this was a woman, Judith Milledge (1927-2021). She also worked with Catherine Lonsdale of londsdalite fame, the hexagonal form of diamond.
More videos on this, if not possible can you tell me where can I educate myself on this topic, For free ofcourse.
Imagine buying a diamond heatsink for your cpu, it's coming
I have a bottle of heatsink paste with micro-diamonds in it.
Will come back to this comment in 10 years
Can you make a video on Atomic Clocks?
Thanks
I wonder if diamonds could eventually be used to make camera lenses?
07:25 2.45 GHz is preferable for use in microwave equipment for reasons beyond magnetron availability. You need to pass tests for radio frequency interference in every country in which you want to sell your equipment. "The frequency of 2.45 GHz is chosen because it falls in one of the bands not reserved for communication purposes." (Physics Stack Exchange) See also Wikipedia's Industrial, Scientific, and Medical (ISM) Radio Band.
What was the context of the question on Physics SE? Diamond production or why 2.45 GHz is used in general? If some other frequency was found to be orders of magnitude more effective for this purpose somehow, I'm sure you could solve the regulatory issue. Apply for a special license and/or build a giant faraday cage around the equipment. If there's a will (and money to be made) there's usually a way.
@@Gameboygenius the microwaves are just used to generate the plasma. There's no magic microwave frequency for that. Other frequencies might need a little more or less power, but avoiding the regulatory headache of using a protected frequency (there's always microwave leakage) means everbody just uses 2.45 GHz unless they really, really need something different and can really, really shield against any RF leakage.
Good for industry
