How much charcoal does it take to make a pound of diamond?

diamond is nothing more than carbon. So in theory you just need a pound of carbon to make pound of diamond. There are two methods to make a synthetic diamond. The first method is using high pressure, high temperature and uses graphite. These diamonds are typically not as pure as natural diamonds. read more

So in theory and roughly estimated you could make ca 2000 carat of diamonds out of one pound of charcoal. diamond prices per carat increase as you jump up to higher weight categories but I doubt you could put a pound of charcoal in the pressure equipment. So, lets say you could make a 0.50 carat diamond for each lump. read more

Coal is a product of preserved organic matter, exposed to moderate temepratures and pressures within the crust. It is mostly carbon. And yes, diamond is an ultra-high pressure allotrope of carbon. read more
