What's the profit margin on a 0.6 gram chunk of fancy carbon being sold for three grand?

Not much, production cost is closer to that of RAM or a CPU than to a graphite pencil, as it's usually produced in the same way as semiconductors are.

The margin is in cutting and faceting. The Swiss make a CNC diamond cutting machine that can cut and facet a diamond in about an hour vs days for manual cutting.
