Diamond prices are down 60% since a 2011 high, and they are still falling. It’s not all down to lab-grown diamonds, demand is down too, especially in China.

No one can lab-grow gold yet, so its rarity and scarcity protect its value, but that will end too. It’s just a question of when. China launched an asteroid touch-down mission this week, which will make it the 4th country/region to do so, after Europe, the US & Japan.

How soon will it be feasible to mine asteroids? Who knows, but a breakthrough in space propulsion might mean the prospect happens quickly when it does. It’s possible gold has twenty years or less of being high value left.

          They are talking about not returning mined material from asteroids but about changing the trajectory of asteroids so that they collide with Earth. But if you do so, the asteroid would likely be destroyed, leaving little to mine, so it would have to be stopped (or slowed down) before reaching the ground.

    Ah, yes, the notoriously accessible and inexpensive field of launching rockets, landing said rocket on a giant sized bullet so a robot can go drill in it for weeks to dig up thousands of pounds of rock, lifting the robot that now weighs significantly more off of the giant bullet, and safely returning it to our larger, slightly slower bullet.

    It’s good to see diamond mining being replaced by artificial diamond manufacturing, which appears to be better envitonmentally and socially.

    But I wouldn’t compare diamonds to gold. Because gold is an element that can’t be manufactured (without a particule accelerator and an insane amount of energy).

    Asteroid mining is still science fiction.

      Would that really help though? Gold is super soft so I think it would need to get frequently coated/plated again — and we already have pretty good and resistant marine paint.

      Titanium is very corrosion resistant, not to mention plastics/fiberglass/carbon fiber, as I understand.

      But yeah, cheap gold would be be great, just seems to me that the market would more be in e.g. electronics, where both corrosion resistance and electrical conductivity are required (something gold is fairly unique at).

        Yeah, well maybe ships weren’t the best example.

        Low wear resistance of gold is a significant issue, which definitely limits the number of potential applications, but I guess gold alloys could still be useful. For example, titanium has a bunch of alloys for different purposes, some more corrosion resistant than others, while others were optimized more towards wear resistance.

        Titanium can also catch fire, which makes it a very tricky metal to use. Putting out a fire like that is pretty much impossible, so if your titanium cladded reactor catches fire, all you can realistically do is try to prevent the rest of the building from burning down. The reactor itself is gone at that point, so all you can do is wish you had paid for the gold cladding instead.

        Also, the electrical conductivity of gold is amazing. If gold was as cheap as iron, we would definitely use lots of it in various electrical appliances.

        If you can mine gold from asteroids, you’re probably also going to find silver and platinum. Those two have some amazing properties too, so I think asteroid mining has great potential to permanently revolutionize a bunch of industries.

          Creating a debris field in orbit? You want this thing fully enclosed before you start messing with it in ways that cause it to break up.

          I suppose in a very low orbit you could consider messy options if it will all burn up in a few months. But doesn’t seem ideal.

          Asteroid miners are going to have more in common with spiders than anything else; find a tasty roid, wrap it up in cling wrap and set off bombs inside of it until it’s a bag of gravel, then get the whole mess spinning and just let go of the stuff you don’t want to keep. Hell when you’re done you can re-harvest the angular momentum to propel you over to the next roid and start the process over again.

          Why would that be a problem? The drilling platform would have to be tethered to the rock, but that’s doable and I’m pretty sure they drill all the time on the ISS. Actually, didn’t we drill into a comet or asteroid for samples sometime recently? The explosives would require no modification at all.

              Barbed harpoons were the approach with the comet. Putting a band around the whole thing could also work for a small body. If you’re going for gold, the asteroid is also going to be paramagnetic if I’m not mistaken, so you can just electromagnet on.

              It’s slightly more problematic than on Earth, but I’m basically going to need some citations if I’m ever going to believe it’s sticking to the chosen landing site that’s the hardest part. A lot of proposals sidestep on-site processing, even, and rely on delivering a whole small body to Earth.

            Yeah, that’s what I mean. People have been overpaying for diamonds for a very long time, mostly because they buy a diamond specifically because it’s expensive.

            A diamond isn’t 1000x better at being a shiny piece of glass on top of an engagement ring than e.g. a cubic zirconia. But it’s about 1000x better at showing that you paid 1000x the amount of money that you would have paid for a cubic zirconia.

            And because of that, if the price of raw diamonds drops, the price of processed diamonds won’t change significantly, because the production cost of e.g. a diamond ring doesn’t matter for the asking price.

      Lab grown diamonds are much better quality than natural diamonds. So now natural diamond companies are moving to the “imperfections is what make a diamond perfect” strategy. But nothing’s stopping labs from growing diamonds with imperfections if that’s what the people are after.

      All in all, diamonds have always been mostly a scam and it’s showing more and more.

        Well, you can make gold atoms (see here), but it takes many times more energy per atom because the energy contained in the bonds between neutrons and protons in the nucleous of atoms is many-fold the energy contained in the bonds between atoms (just see the difference in potency of conventional explosives - which release energy contained in the links between atoms - and fission and fusion bombs - which release the energy contained in the bonds within the atomic nucleous) hence it’s not really an economic viable way of making gold.

      I totally get where you’re coming from—on the surface, it does seem absurd that so much effort, money, and even space tech is being directed toward chasing a shiny yellow metal that, in practical terms, doesn’t do much for human survival. It can’t feed us, shelter us, or cure disease. And yet, we’ve built entire economies and mythologies around it. But the strange part is, this isn’t unique to gold. It’s part of a much deeper pattern in human economic systems, especially in capitalism, where markets need some way to store and measure value—and that almost always leads societies to latch onto something rare, durable, and symbolic, whether it’s objectively useful or not.

      In early societies, people used cowrie shells in the Pacific Islands, huge stone disks in Yap, salt in ancient Africa, and even tulip bulbs in the Dutch Republic. These weren’t chosen because they had immense utility, but because they were scarce, hard to replicate, and symbolically powerful. They allowed people to trade across time and space. Capitalism, being based on decentralized exchange, competition, and accumulation, basically demands a store of value that everyone can agree on—even if the object itself is more symbolic than practical. Gold just happens to check all the boxes: it’s rare, doesn’t tarnish, can be melted and divided, and most importantly, it’s extremely hard to counterfeit or mass-produce without massive energy investment.

      If gold didn’t exist, we’d be doing the same thing with something else. In fact, that’s basically what happened with Bitcoin. People wanted a store of value outside the control of central banks, and they turned to something even more intangible—just math and energy. It’s the same pattern: we create artificial scarcity and give it value, because we need a common reference point to coordinate vast, impersonal economies.

      Now, the asteroid mining thing? Yeah, it sounds wild. But from a capitalist perspective, it actually makes sense. If gold remains valuable, then any untapped supply—even in space—is a business opportunity. The fact that this seems grotesque when we think about all the hunger and suffering here on Earth is a painful contradiction, but it’s also part of the logic of capitalism. Capital doesn’t naturally flow toward moral priorities like feeding people; it flows toward returns. And unless there are incentives or systemic shifts to redirect that flow, people will keep pursuing things like asteroid gold, because that’s where the value signal points.

      So yeah, it’s kind of maddening. But it’s not really about gold being useful—it’s about human systems needing anchors of value. And gold, for all its impracticality, happens to be an anchor that capitalism can rally around.

      It’s universally obtainable but not in ridiculous volumes and not without effort and once obtained it’s incredibly durable. It’s essentially perfect for the job.

      While I agree it is overvalued, what really put it into perspective for me is that all of the known gold in the world would fit into a cube with a side length of 20-25m.

      So a fair price would be lower than what it is now, but it is scarce and its uses (corrosion resistance, conductivity, malleability, reflectivity, etc.) probably would still warrant a relatively high price.

      Gold has plenty of uses, besides being shiny and easy to work with. Imagine if all your electronics used gold traces because they were so cheap. Imagine if the windows of your car were coated in gold like on an airplane so you could easily defrost them in the winter rather than blowing air at it in the front and potentially distracting lines in the back. Imagine if gold was the filling of choice since it has a similar expansion rate to teeth. Gold has a number of applications in space. Ever wonder why the JWST is that color?

      There are plenty of things gold would be excellent for if it wasn’t so expensive.

        It’s abundant though. We have thousands more times gold in circulation than used as jewellery. So if it were just jewellery then it’s be dirt cheap.

        The reason its so expensive is people use it as investment. Like they hold massive amounts of it. It’s like a made up commodity.
