The problem wouldn’t be fixed even then. The jewelery companies have people convinced that the only diamonds that are worth it are mined from the earth by a real human slave. Fixing that problem has nothing to do with gemstones.
Me too. I’ve also heard synthetic gemstones can have colours and structures unlike anything that can form naturally. I want one of those, so that nobody would mistake it for a mined stone.
Yeah, the optical quality seems to be the main point. I assume there’s few fields where that level of precision is worth it though. I doubt we’re about to see it on an iPhone any time soon.
Not a catch, majority of diamonds are used in industries and need to be small.
It’s a catch when your perspective is hoping it will impact the negatives of the jewelry industry.

Is this still the case? I feel like I’ve seen “conflict free” as a selling point for (presumably labgrown) diamonds.

What’s the biggest synthetic diamond we’ve made so far? Has anyone made diamond spectacles or windows?
They’re quite brittle, so probably not a window like you’re thinking.

10mm diameter for just over £1000.
Ah, so still not quite Cullinan-scale yet. Optical quality is probably better though.
I’m surprised diamonds aren’t used more for lenses. Given its high index of refraction, it seems like an ideal material.
