Reply to comment by punk_rancid in It's weird that diamonds are so valuable. They're just shiny objects. by SenorDipstick

That's probably partly because tools containing diamond are made with synthetic diamonds instead of mined diamonds.

Some jewelry are also made with synthetic diamonds, they are a tad bit cheaper but still cost an arm and a leg.

Yeah because they know people will pay for it whether the diamond is synthetic or not, the marketing has done its job. I'd be interested to see the profit margin they take in for natural vs synthetic jewelry diamonds.

For the natural one the profit margin is already huge(read it like trump says it) i imagine that for the synthetic ones is even huger(?)

A big difference is tool diamonds are polycystalline (atom are different directions) where lab grown diamonds are single crystalline (or attempted to be) so the clarity is different.

Also, tool diamond are normally created by HPHT process where jewelry is normally CVD process. Different time and cost per stone.

Very interesting. Out of curiosity, how do you know that about synthetic diamonds and its processes?

I work at a place that makes the diamonds using CVD.
