Diamonds cost significantly more than coal because they contain a lot of gold. In terms of price, a one pound diamond can range from 2 million to 6 million. A pound of coal is worth a few pennies. Despite the fact that diamonds are more expensive than coal, coal is more valuable. In many ways, diamonds are more similar to coal than coal.

Coal Doesn't Play A Role In Diamond Formation! Contrary to what people assume, diamonds do not form from coal in any way. A comparison of the age of Earth's diamonds and the age of the earliest land plants is the most convincing proof that coal did not play a role in the formation of most diamonds.
