Proof, in the form of a diamond Snoo:

I am a diamond geek, Stanford CS grad, and the accidental founder and CEO of Ada Diamonds. We pressure cook carbon into diamond at a million PSI and 1500°C, and then we make custom made-to-order jewelry with the diamonds. In addition, we supply diamond components to Rolls-Royce and Koenigsegg (maker of the fastest production car on Earth @ 284mph)

Here's a recent CNBC story about my startup and the lab diamond industry.

I believe laboratory grown diamonds are the future of fine jewelry, but also an important technology for a plethora of functional applications. There are medical, industrial, scientific, and computational (semiconducting and quantum!) applications of diamonds, and I'm happy to answer any questions about these emerging applications.

I also believe that industrial diamond mining is now an unnecessary evil, and seek to accelerate the cessation of large-scale diamond mining. We are well past 'peak diamond' and each year diamond mining becomes more carbon-intensive and less sustainable.

Edit - I'm throwing in the towel. Thanks for all the 'brilliant' questions! #dadjokes

What effect would the man-made diamond industry have on the price of diamonds as a whole?

Would it make them more cost effective for the consumer or will it remain similar?

Thanks for the AmA!

Ada_Diamonds14890 karma

This is a really important question - please upvote!

IMHO, the price of mined diamonds is about to fall precipitously. Why? It's not because of synthetic diamonds, but instead because a diamond is forever, but Baby Boomers are not.

Think back to WWII and the decades that followed. The massive improvement of machinery during WWII resulted in a massive increase in diamond mining production. Then you had the 'diamond is forever' campaign result in a massive increase of purchases of diamonds by Baby Boomers.

Almost every car, fridge, and radio from the 1950s has long been destroyed, but virtually every diamond bought in the 1950s has the exact same utility today. Those diamonds are about to flood the market, in significantly more quantities than lab diamonds ever will.

There is a joke in the diamond industry that the biggest diamond mine in the world is in Florida and Arizona, but the mine is the pawn shops, not the Earth.

So Econ 101 - demand for diamonds is relatively stable, but supply is about to shoot up. Thus I believe we're going to see a sharp fall of diamond pricing.

The mined diamond lobby wants to blame millenials, lab diamonds, rent prices in NYC and SF, or anyone else, but the real answer is that the problem is that a diamond is forever, but humans are not.

AgnieszkaXX509 karma

Wow, that sure gave me something to think about. I guess I just assumed all these diamonds would be passed down as heirlooms or something, but that's true for only a portion of them and the other half would get sold!

Rashaya966 karma

Even if it did get passed down in the family, it would still affect the industry. Every time a guy proposes with a ring that used to belong to his grandmother, that's a newly mined diamond that isn't being bought.

Ada_Diamonds69 karma


enigmahack826 karma

Thoughts on moissanite? My wife has a moissanite ring because she is heavily against DeBeers, the artificial scarcity of diamonds, blood diamonds, and so-on.

Is what you're doing similar? How are ADA Diamonds different?

Ada_Diamonds473 karma

I admit my biases, but I am not a big fan of moissanite. I guess it's because it makes my head hurt the same way a chess grandmaster gets completely discombobulated if you show them a board that is not physically possible.

We do not sell moissanite or CZ, we only sell diamond.

Lastly, I genuinely believe in the positive externalities of lab diamond gemstones, hence my enthusiasm for them.

pulpbear749 karma

How large can the diamonds get? How did technology improve in order to create diamonds larger than 0.40 carat?

Are you able to recycle the diamonds?

Can/will you make colored diamonds, aka those with impurities?

Ada_Diamonds1169 karma

The record for a diamond gemstone is 15 carats. The record for a diamond plate is 92 carats IIRC.

The driving goal of the industry is *not* a 100 carat gemstone, but instead 4" wafers of diamond to replace silicon as a semiconductor substrate... blue diamonds are the best semiconductor know to man!

Not sure I understand recycling a diamond, what do you mean?

We do offer fancy-colored lab diamonds, and they are significantly less expensive than fancy colored natural diamonds. While a natural blue or pink diamonds can sell for millions of dollars per carat at auction, lab grown yellow, blue, pink, red, green, and black diamonds are only a small premium over the price of colorless lab diamonds.

pulpbear269 karma

Hey thanks for answering! That's interesting about boron, and makes me curious if you could create never-before-seen diamond colors to increase possible conductivity or even for other uses. Seems like quite the expensive alternative to silicon. I'd take a purple, though!

By recycling diamonds, I guess I meant if there was a quantity of discarded gems or a mass of industrial stones no longer used, could you "melt" them and regrow it back into something gemmy and more valuable? Like aluminum recycling or something.

Ada_Diamonds532 karma

You are correct, there is one color of lab diamonds that is not possible in mined diamonds: gray diamonds.

Why is this possible in a lab but not nature? These diamonds are grown via CVD in a vacuum, and the resulting crystal of carbon can intentionally be grown with voids in the crystal, almost like freshly fallen snow has air between the H20.

You can then heat the diamond, and the carbon atoms around the voids revert to graphite, leaving billions of nano-graphite particles in the crystal.

The optical effect is a smoky, sexy diamond with all the fire and brilliance of a white diamond.

Here's two pieces we've done with gray diamonds:

We also did an awesome two stone ring with purple diamonds.


No need to 'recycle' diamonds to grow diamonds - it's much more efficient to use readily available graphite or natural gas as a carbon source.

rdavidson24689 karma


So, here is a memento of my late grandfather that I have on my desk at work. I think it's from the 1970s, possibly the 1980s. "Shock synthesized polycrystalline diamond" embedded in some basically indestructible plastic from the same company, DuPont. What I've been told is that the silvery lumps in the copper section are diamonds, but I have no way of verifying that.

What can you tell us about that process? Is that what you use? If not, how is yours different?


Ada_Diamonds1103 karma

Basically an explosion creates very high temperature and very high pressure for a very brief moment. If done correctly, diamond can grow in these conditions, but their size remains quite small, due to the short time. The HPHT (high pressure high temperature) process creates similar temperatures and pressures to your grandfather's shock process, but sustains those conditions for days or weeks at a time, allowing the diamonds to grow into gemstone sizes.

Fun fact - there is an entire city in Europe filled with diamonds in the streets, steps, etc. because of an asteroid impact shockwaved the forest into diamonds.

theviqueen587 karma

Hi! Is this cost-effective? Like, I imagine it must be way cheaper than mining diamonds.

Also, would it be possible to make rubis or emerald or other precious stones in a lab as well? And could we extend this to other natural stones such as lapis lazuli, jade or tiger’s eye?

Ada_Diamonds1062 karma

It's not way cheaper, and it will never be cheaper IMHO. Source: De Beers mines diamonds at $107 per carat IIRC.

Diamonds are not like iPhones. There will not be a Moore's law for diamonds where it gets exponentially cheaper to grow diamonds. Why? There is a *speed limit* to how fast you can grow a diamond crystal. Grow it any faster and the crystal will get inclusions/microfractures in the diamond.

Yes, rubies, sapphires, emeralds and other stones can be grown in a lab as well, but not all types of gemstones can be grown. AFAIK you cannot grow lapis lazuli, jade, or tiger's eye.

GlyphGryph287 karma

I mean, there must still be economies of scale though.

How long do the diamond making machines tend to last? If they've got high turnover, maybe not. But if they last a long time you'd expect diamonds to get cheaper and cheaper as older models continue churning.

Ada_Diamonds371 karma

Yes, there are some economies of scale coming, but we're talking marginal, not exponential.

Why? This *is* a mature technology. GE grew the first diamond in the early 1950s. De Beers has been commercially selling diamonds since 1960.

De Beers is investing $94m to grow 200,000 carats of gemstones (by 2020). If they invested $1Bn instead, they would not get 100x the production, they *might* be able to get 12-15x. (just a WAG, no data to back that up)

s0rce63 karma

Why is there a speed limit? This would seem like a limit of current technology not a fundamental physical limitation. There is a lot we don't know about crystal growth.

I have a PhD in materials science and am genuinely curious.

Ada_Diamonds79 karma

I'll admit I'm out of my element to definitively answer your question, as I'm just a computer scientist, but I'll try my best.

If you grow CVD too fast you get voids in the crystal structure, not really a big deal for most functional applications, but it give an undesirable brownish/grayish/yellowish tinge to the crystal the way that light interacts with the voids.

For HPHT, the crystal is grown at ~7GPa and 1500C, which is right on the verge of the melting point of carbon at that pressure. You're convecting liquid carbon by the seed and adhering the carbon atom by atom, and my understanding is if you try to grow the crystal too fast, you'll get stress cracks in the crystal.

Again, sorry I'm a bit over my skis on a definitive answer here.

PS - I do know that if you grow nitrogen containing diamonds, you can grow the crystal faster :)

SpecialistCoconut16 karma

The "speed limit" you mention is kind of similar to proof of work in blockchain technology. Would it be possible to grow a diamond slowly while encoding information in it to serve as an indisputable ledger?

Ada_Diamonds126 karma

Turns out that pink lab diamonds are the best 'hard drive' known to mankind.

First you put the lab diamond in complete darkness, then you can use a laser to put a photon in the nitrogen-vacancy defects in the diamond.

That 0 or 1 will last for eternity, and is potentially the future of long term data storage that is currently decaying on HDDs, SSDs, DVDs, etc.


kingshmiley437 karma

What timespan to you foresee before diamond mining is for the most part phased out? What sort of pushback do you expect from the mining industry and how do you plan to combat it?

Ada_Diamonds952 karma

Somewhere between 20-50 years from now. I've pulled all the public filings from all the major diamond miners and there are about 1.6Bn carats of diamonds in known reserves, while ~6Bn carats have been dug out of the Earth in the last 150 years. So we are well past 'peak diamond' at this point.

If there were a carbon tax levied on mining, the cessation of diamond mining would happen a lot sooner than otherwise.

De Beers and the other diamond miners have invested $133m in PR and lobbying to fight lab diamonds, largely unsuccessfully. I don't know what's next for them, given that De Beers announced last week that they will start to sell lab diamond jewelry.

How do I combat it? I don't need to. My clients are too smart to buy the 'fake news' that a lab diamond is 'fake.' They view grown diamonds as a paragon of human achievement and proudly tell all their friends about the origin of their diamonds as a feature, not a bug.

I'm far more supply constrained than demand constrained at this point.

Grandpas_Spells384 karma

De Beers will sell lab-grown gems at a huge discount in an attempt to destroy the market for lab grown diamond jewelry.

Ada_Diamonds623 karma

That is the general consensus in the industry.

That being said, I fully support De Beers entre into the market ( and encourage everyone to consider purchasing a lab diamond from any of the purveyors, including De Beers.

Why? Every lab diamond gemstone purchased directly funds the medical, industrial, scientific, and computational applications of diamonds.

Brothernod362 karma

I bought a lab grown diamond 4 years ago for an engagement right and the company no longer exists. I’ve tried searching for a similar company that lets you buy loose stones and did not come up with much. Is the lab grown industry floundering?

I was hoping lab grown would be an affordable way to get a set of large brilliant yellow diamond earrings.

Ada_Diamonds490 karma

The lab diamond industry is not floundering, in fact every major producer of lab diamonds is currently doubling or tripling their production.

We are often supply constrained, not demand constrained. I don't want to get commercial here, but we will happily sell you loose yellow diamonds, or a custom pair of earrings - our website is in the initial post.

HitTheBaby205 karma

Is it possible to make a diamond fleshlight?

Ada_Diamonds698 karma

We are in the business of saying yes to our clients. While we have yet to make a diamond sex toy, we gladly would. I personally think a diamond cock ring would really jazz up any marriage.

SpecialistCoconut202 karma

Do you only make jewelry? Are there any medical applications for your diamonds? (I am a doctor)

Ada_Diamonds500 karma

Here's a few medical applications I'm tracking:

  • diamond scalpels for surgeons: in addition to being extremely sharp, have the benefit of being optically transparent and you can actually shine a laser through the tip of the blade for ultra-precise medical procedures.
  • diamond vertebrae and hip replacements:
  • Drug Delivery via nanodiamonds:
  • Diamond optics for more precise lasers (surgery, etc.).
  • Histology - studying biological samples and tissues, use diamond blades for ultra-thin slicing during sample prep and can cut samples as thin as 100 nanometers

And my personal favorite:

  • Early detection of Alzheimer's, ALS, cancerous tumors, etc. via very precise magnetic field detection.

Also, it is much more efficient than the status quo to generate ozone with boron doped diamonds, making sanitation and water purification much better. De Beers is a big player in this space:

haahaahaa177 karma

My understanding is that diamonds are just the result of pressure, heat and time. How long does it take to create a diamond? Is there a size limit to what you can create?

Ada_Diamonds363 karma

Size limit: maintaining the correct pressure and heat is one of the most precise and difficult processes that humanity has ever harnessed. It took 60+ years to get to the point that we could grow 1 carat diamonds. The biggest growth cell today is about the size of an egg. I don't see that going to a baseball or volleyball anytime soon.

The goal that is driving the entire industry is 4" wafers of diamonds, as diamond is the ultimate semiconductor and the future of computing. I do see that happening in my lifetime (I'm in my 30s).

It takes 7-10 days to grow a 1 carat lab diamond, and about a month to grow a 3 carat diamond. If you try to grow a diamond any faster, the diamond crystal will fracture. Thus, there is a physical speed limit to how fast you can grow diamonds.

brokenha_lo75 karma

Business idea: "Donate" blood over the course of several months/years. Harvest the carbon from the blood, and turn it into your own diamond for an engagement ring. Romantic or creepy? You decide.

Ada_Diamonds189 karma

We have a patent pending to grow diamonds from your breath, as you exhale 4-5% CO2 with every exhalation.

Same net result of your spirit encapsulated in a diamond, but a lot less creepy IMHO.

Maladjusted_Jester73 karma

What are the costs of the materials involved in the process and the machines used? Do you think it will eventually see home versions like 3D Printers, Crisper, etc?

Also, is it only more costly because the slave wages are so inexpensive in other countries?

Ada_Diamonds166 karma

For gemstone quality diamonds, you are talking about *massive* machines. Our largest diamonds are made in machines that weight ~70 tonnes. Thus the concrete slab required to hold the machine is 1+ meter thick.

In addition, the 'recipies' to grow the diamonds are actually more important than the 'ovens' if that makes sense. Those recipies take decades to perfect and are as closely guarded at the KFC and Coca-Cola recipies.

Now there are esoteric ways to make small diamonds with explosives that you can do at home. IIRC Mythbusters did this a few years ago.

Brothernod70 karma

Can you make a diamond out of a human’s cremated remains?

How big would it be?

Also, can you add to it later?

Ada_Diamonds134 karma

Yes, you can make diamonds of of cremated remains. That being said, we have made a business decision to not make these diamonds. We instead focus on diamonds grown from life's greatest memories, not life itself.

likethesearchengine47 karma

Is there any ethical diamond mining, in your opinion?

Ada_Diamonds90 karma

It's a tough question, especially given the wealth of the people mining diamonds artisanally in Africa. So you stop that and you unethically hurt a lot of vulnerable people, but you keep it going and you damage a lot of riversheds, pollute a lot of water, and hurt a lot of animals.

Now I strongly believe that there has been and continues to be a lot of unethical behavior by large diamond mining corporations, well documented by the UN, the US State Department, BBC, Human Rights Watch, etc.

Let me ask your opinion - say we applied a proper carbon tax to the large diamond mining corporations, and industrial mining were to phase out over the next 20 years - would that not be a good thing for the price of diamonds and the livelihoods of artisanal miners?

To be clear, most mining is necessary: the human race needs lithium for our batteries, iron ore for our buildings, oil for our transportation, metal for our power lines, and rare-earth elements for the device on which you are reading this article. Diamond mining, by contrast, has now been made unnecessary and obsolete by modern technology. Humanity can culture diamonds in laboratories that are objectively superior to the diamonds cultured in the chaos beneath the Earth’s surface, neatly avoiding potential corruption, conflict, and ecological damage at the same time.

Unfortunately, the unsustainability of diamond mining is accelerating; each marginal carat mined is more difficult to extract and more energy intensive than the last. Despite the best efforts of the mining industry to expand diamond mining operations around the world, humanity has already passed ‘peak diamond,’ extracting 25% fewer carats in 2016 than we extracted a decade ago. Quite simply, all the easy to get diamonds have already been extracted.

Here's a great read by a former BBC reporter about the industry: Glitter & Greed (Amazon)

_afikomen_47 karma

What is the most interesting thing you have turned into a diamond?

Ada_Diamonds167 karma

My favorite that I have made to date: We made an engagement ring for a client that met his now fiancee skydiving. He gave us *grass* from the drop zone where they met for the first time, pictures of the couple, her favorite flower, and their favorite beer.

We graphetize the material, like a wine reduction sauce, and then pressure cook it into a priceless diamond.

Here's the donor material:

Here's the finished ring:

The thing I am most looking forward to making? A diamond for myself from the S-1 filing when we IPO or the contract when a luxury conglomerate acquires us :)

Your fiance is awesome. It was such a pleasure to work with him.

cahaseler39 karma

How much is that proof worth?

Ada_Diamonds118 karma

We put it together quickly without weighing all the diamonds, but I would guess it's about 3 carats total, so set in platinum we'd probably sell it for $4-6k.

That being said, we can make it as big as you want and price would go up from there. You want a diamond Snoo the size of a Flava Flav Clock, we can make you that for ~$100k.

cahaseler68 karma

Hey everyone, hear that?

Get over to our Patreon, we can get the $100k one if you all donate!

tubnotub138 karma

A lot of watches and even now some phones are using sapphire crystal in order to protect their faces/displays because of how durable it is. Is there anything preventing diamonds from being grown and used in a similar way beyond cost-effectiveness?

UltrafastFS_IR_Laser76 karma

I can answer this. In applications for protection and what not, sapphire is much cheaper than diamonds, something which even lab manufactured diamonds will not be able to touch. Diamonds and sapphires have quite a lot in common too, with sapphires being just slightly less hard. The main prohibitive thing is the cost. It takes a lot more for labs to make the diamond compared to the sapphire and the gain in durability/scratch resistance is minimal.

Even in our lab, diamond isn't really that great and we prefer sapphire for nearly all applications besides cutting. Sapphires also have a cleaner optical window than diamonds.

Ada_Diamonds52 karma

^ I'm with this guy.

You'll see diamond heat spreaders in your phone first, and the diamond semiconductors. Probably not going to see diamond crystals for a few decades if ever.

Nakedstar34 karma

In your opinion, are memorial diamonds going to get more popular as lab created diamonds become more popular?

Drunken_Economist25 karma

How much for the diamond snoo?

Ada_Diamonds32 karma

$4250 in platinum :)

WaffleSparks24 karma

So if you sell a man made diamond for lets say $1000, how much of that $1000 did you spend on energy costs while producing that diamond?

Ada_Diamonds43 karma

Good question. The most efficient growers are around 250 KwH per carat and the least is around 750 KwH per carat. So a decent amount, but not a dominant amount of the cost.

The fixed costs and the price of PhDs in physics, material science, etc. to run the equipment are the two largest costs.

Wobblycogs21 karma

If I wanted to get into diamond making what would I need to learn and how much would it cost? Asking for a friend, obviously.

Ada_Diamonds42 karma

A *lot* of materials science. There are academic institutions around the world growing diamonds that would gladly work with you :)

Michigan State is doing some amazing work with diamonds!

RocketHammerFunTime19 karma

What is your favorite cut and weight for diamonds?

What other gems would you be interested in making (that either you arent now, or only in smaller amount)?

BluePinky6 karma

From what I understand, the reasons diamonds are expensive is because they are rare, and the more of the 4 C's they have, the rarer they are, hence the higher cost. If lab diamonds flood the market, and companies can manufacture them, wouldn't the price of diamonds tank?

Ada_Diamonds19 karma

Combining data from the Gemological Institute of America (GIA) and the Kimberley Process, approximately 6 billion carats of diamonds have been mined out of the Earth since antiquity. According to GIA, “The total global production from antiquity to 2005 is estimated to be 4.5 billion carats valued at US$300 billion, with an average value per carat of $67.” From that 6 billion carats of mined rough diamonds, there are approximately one billion carats of diamond gemstones that were cut and polished and are now owned by individuals all over the world.

In 2017, approximately 142 million carats of diamonds will be mined out of the Earth and approximately 2.3 to 4.2 million carats will be grown (according to a recent global survey). Thus, lab diamonds only make up 1.6 to 2.9% of annual global diamond production today. Morgan Stanley predicts that portion of lab diamond sales will rise to 7.5 to 15% by 2020.

Ada believes the much larger threat to the value of mined diamonds is the recycling and resale of previously mined diamonds, a space that De Beers recently entered. Experts estimate that the Baby Boomer Generation in the United States owns over 500 million carats of diamond gemstones which will be inherited or resold in the next few decades. These diamonds will be gifted or sold. These ‘used’ diamonds are often recut and reset, then sold as ‘new’ mined diamonds.

Mortymoose693 karma

I have lived on a diamond mine in Namibia for the past 45 years. The mine is a DeBeers mine and has been operational since 1936. In that time, the mine has provided employment, education and contributed massively to the fragile economy of countries like Namibia and Botswana. These are not blood diamonds and the revenues generated have benefited many. Do you consider it a positive thing to see these two countries in particular lose their primary revenue stream once the age of diamond mining ceases due to artificial stones?

Ada_Diamonds5 karma

No, I don't think that there are blood diamonds in Namibia (other than the seal hunt on the Namibian beaches, but that's something of a tangent).

However, let's talk jobs and Namibian diamonds. My understanding is that the on-shore mining in Namibia is winding down because all the diamonds have been extracted, no? IE Namdeb is shutting down and Debmarine is growing, correct?

De Beers is spending $600m+ right now to build another deep-sea mining vessel. It will only employ 140 people when operational IIRC. It's being built in Norway, so most of the construction jobs are *not* going to Namibians.

Say De Beers instead spent ~$100m on a solar plant and ~$500m on a diamond 'gigafactory' in Namibia:

  1. The facility would employ more people than the vessel
  2. The construction would put far more dollars directly into the Namibian economy
  3. The spare electricity could be donated or sold at a low cost to the local communities
  4. The gigafactory could be built where the land has already been disturbed by the mining process, minimizing the environmental impact

The way I see it, this course of action would be far more beneficial to the people of Namibia than the current trajectory of Namdeb and Debmarine.

But I'm obviously not plugged into the true happenings of the Namibian economy.

Can you please give your honest thoughts on my proposal? I'd genuinely appreciate it!

iamsubhranil2 karma

what's more costlier - lab grown or mined?

Ada_Diamonds11 karma

It's counterintuitive, but it is far more expensive to *grow* a diamond than it is to dig one out of the Earth.

That being said, we have a very efficient supply chain so we are able to sell lab grown diamonds for around 30% less than comparable quality mined diamonds.

BigStickPreacher1 karma

How are you going to combat the huge stockpiles of diamond keeping the markets artificially high? They will be released at some point, maybe expressly to destroy business like yours and it would be wise to have a game plan.

Ada_Diamonds8 karma

AFAIK, there *was* a big stockpile, but that was released to the market when the Russians broke the De Beers monopoly in the 1990s.

They can try to destroy our business, but I believe that today's consumer is too smart to fall for the fear, uncertainty, and doubt spread by the Diamond Industrial Complex (DIC)

I'll bite and defend myself.

I've spent years working in philanthropy. I've put my own life in danger to help others less fortunate than me.

President Clinton loves my work, and Stanford teaches a case study about my Philanthropy Engineering efforts.

Lab diamond gemstones are *not* useless. They, in fact, fund the future of technology:
