Are Man-Made Diamonds Really Diamonds?

Natural diamonds take a long time to form and can be dangerous to harvest, but how hard is it to make some in a lab?

As James Bond has so sagely instructed us, diamonds are forever. Well, at least they take forever to form. The diamond on any given wedding ring is at least a million years old, and possibly more than a billion years old. The ones we can mine with current technology were formed deep in the Earth's mantle and spit up by ancient volcanic lava flows.

Artificial diamonds are another story. Incredibly, we can actually make diamonds in the lab that have the exact same structural and chemical composition as those mined from the Earth.
