Lab-made diamonds: It’s a giant scam, but you’re still going to buy one

I only want a synthetic diamond if it is monoisotopic and has 10x the usual heat conductivity.

when i was younger, i hoped that in the future lab-made diamonds would make it feasible to buy one the size of a baseball for not that much money.

Mined diamonds. It's a giant scam but you're still going to by one.
