The geoengineering scheme, known as stratospheric aerosol injection, would not be cheap, but scientists say it could buy us some time until we reach net-zero carbon.
That amount sounds like total bullshit. Diamonds can be manufactured and once that is done at scale, it won’t be all that expensive. Even at $10000 a ton, five million tonnes would cost just 50 billion.
That number is for doing it anually for 65 years. It lists roughly 18 billion per year for the cost.
But besides that, I think you are greatly underestimating the cost of the diamonds. Synthetic ones are way cheaper than natural ones, yes, but there’s a lot of room between “natural diamond expensive” and “actually cheap”.

It’s $2.5 million per tonne. I assume you could get a cheaper price per weight if you’re buying five million tonnes of anything, but it’s still two orders of magnitude more expensive than you are guessing
These are not good ideas. Remember that global warming is just an overarching effect of pollution which we will still have. What diamond dust pollution effects will be, no one knows, but I doubt we want to find out.

The fossil fuel oligarchy would prefer to give all mammals on Earth emphysema than stop burning fossils, and do it for 10x the price.
