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

Yeah hexagon in fake 3D things Have a look at TEDx fourth phase of water.. just the same as graphite in structural terms. We were so blind.

Inarguably perhaps 🙃

@@goldnutter412 diamond mining companies will argue and I welcome them to, I will employ very childish arguments and waste their time 🤣

I think that a really awesome gift would be a DIY CVD diamond. The process feels like it's right on the edge of where DIY is possible.

Those AuDiaTech diamond wafers are just what I need to defrost my hamburgers on the kitchen counter!

How well would diamond heat sinks work

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.

@@reviewchan9806 I could cut one now and find out. I have large diamond wafers.

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

Sapphire is not good enough?

@@Vatsek lolz talk to Apple bout that one hahahaha

What is still not discussed here -- because it is out of context -- is how the cartel fights back or tries to survive.

@@Vatsek Good question: Optical-grade synthetic sapphire is well known for its excellent optical properties from IR to UV wavelengths, particularly UV. There is a strong absorption band from F-centres at 200 nm, but this can be removed with suitable treatment, extending the optical window to 150 nm. Sapphire also has excellent mechanical properties; however, it is still not hard enough to resist rain-impact damage at high velocities. Diamond is the _only_ known material which can do this. Also note that sapphire is a birefringent crystal, which can complicate optical design.

@@JohnnieWalkerGreen I agree, you are off-topic.

But jobs? 😂 If I know miners they'll fight to keep mining.

Let them go back to collecting bannanas and tribal stuff or w/e​@@Lazerecho

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.

I'm more worried about the exploitation of grooms in the wedding industry.

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. "Henri Moissan's method involved using a tube furnace to heat a mixture of fluorine and carbon to high temperatures, causing the carbon to sublime and recrystallize as diamond. This process was later refined and improved upon by other scientists, leading to the development of the chemical vapor deposition (CVD) method for diamond synthesis." How long have they been making SYNTHETIC DIAMONDS (1950's according to mainstream sources)? That would seem like a crucial tid bit of Intel to know.

@@neveralonewithchrist6016 I have a specimen that produce natural cvd diamonds.

@@neveralonewithchrist6016 the magic trick with thin films is uniform thickness. That was absent until fairly recently.

I've been dreaming of asking a local company that makes industrial monocrystalline diamonds if they have any QC rejected pieces like that for this same reason

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.

Okay, snowflake.

Ahhh, good one

Your preference means nothing to these engineers and scientists. Sheesh. I prefer you wash your hands.

Based, as one may say

@@benruniko ‘Based’? Who would say? You? The one who dropped out of school? One would say you are foolish.

any new directions with ai models you are willing to share?

You are a tech priest.

​@@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.

Took me a few seconds to realize that. Such a dry humor..

Happen to all of us 😂😂😂

Indeed only q matter of time!

Single entendre.

I can think of a few ways to inject an electron in, but they'd all introduce lattice defects, which would be double plus ungood. :/ What energy level is the outer shell electrons at? Maybe resonate them a bit in the presence of an electron donor?

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.

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

The fact that ppl want a piece of glass on a hoop is beyond me

@@bot7845 It's because SHINY! Some people identify as magpies.

The fact you think everyone should think like you is just ridiculous.

@@gravityissues5210 I do not think that everyone should think like me. I just think you are ridiculous

IPA fails in KZfaq comments; the comment is rejected and vanishes. 😞

Don't get me started on water, it's just weird anyway. Go any distance away from STP, find yet another phase for the stuff. As in there's evidence to support the existence of ice inside the earth's mantle. It'd drive me to drink, but I already beat them to the punch. ;)

@@spvillano Yes, I believe water (ice) has more known crystal phases than any other pure material. Its strange properties are in part a consequence of the cooperative nature of hydrogen bonding. Then we have matters such as proton disorder and the Bernal-Fowler rules in normal hexagonal ice!

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!

Like Al Jolson.

wahlet

@@KingLich451 It just hit me! It's the same way Thumper says "violet" in Bambi

Very few people have such concerns outside of niche markets frequented by the heirs to vast fortunes or the occasional irresponsible clout seeking middle class future divorcees.

Nowadays, manufactured diamonds are indeed cheaper monetarily than mined diamonds. And many people do seem to want the natural diamonds due to the perceived romanticism of it. But that said, other than Canadian diamonds, mined diamonds are not very traceable and are implicated in human rights violations. Not very romantic IMO.

@@benjamindover4337 In some cases yes, in some cases no. It depends on the situation. If you're a more experienced and older seller, you have a clientele built up over years that will come in and buy anything that they fancy. I'm of course speaking from experience I had over a decade ago. The diamond industry was a lot different even then. That shows you how little time it takes for technology to catch up. I was there for only 9 and 1/2 to 10 months but in that time I sold a few nice pieces to be sure. The one carat diamond was our main focus. The only issue I see is that you cheapen the experience and the symbolism is lost if you make diamonds, particularly those for engagements, so cheap. It's something you should have to strive for and it's something that she should have to appreciate. Or else you get another scene like in the movie Baron Munchausen, where she just tosses the diamonds into a growing pile

@@benjamindover4337yeah yeah _you_ don’t see value in it so it must be only a handful of people on the earth who have some esoteric interest. Meanwhile I’ll trust the word of the actual salesman who made a living working for a large corporation who actually made money marketing these.

@@gravityissues5210 Access denied. Do not pass go. Go directly to jail. 🤷🤷🤷

Well, the microwave plasma was used in physics labs for decades too. Hell, the fusor uses that tech to initially ionize deuterium.

He already did... Sort of. Did you see the one on atomic layer deposition?

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.

They also decorate their home with furniture...

@@_general_error what homes?

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.

@@gravityissues5210 the people have spoken

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

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.

Correct

I don't know. I think Jon is more of a 9N purity silicon kind of guy.

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.

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.

I believe there is research that is seeking to do just that.
