I find it quite amazing that something that hard can be cut with such precision. The only thing that can touch and mark it is diamond, so to carve it would take working with a cut and mounted diamond point or rotating diamond dust wheels. That - and optics to see what you are doing.
And to say that was achieved 2000 years ago is simply amazing.
