normally Free don't interest much about jewelry, just a few bit from fantasy properties.

recently Free found video about aftifical diamond, as it hardest item in the world, demand of it from industry that not care about origin.

to make it feel so easy process, just put carbon (pencil core) in press machine, press it in safe metal box just in case. then you got diamond.

Free seem to like some heavy industry machine lately.

a lot of humanity progression in it.
