They're quite brittle, so probably not a window like you're thinking.

10mm diameter for just over £1000.

10mm diameter

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.

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.
