A red-and-green rock stuffed with "30,000 teeny-tiny diamonds" was unveiled this week at the American Geophysical Union's annual meeting. Though the sparklers are too wee to have value as gems, the unique rock, discovered in Russia's Udachnaya mine, may help geologists better understand how diamonds are formed.

The mineralogy behind how these kinds of ores form is indeed intriguing. There are still some big mysteries about how the Earth forms these kinds of rocks. And we'll learn more about our planet once we crack those mysteries.

But diamonds themselves? Not so much. Now that we can grow them in labs out of peanut butter we need to realize it's just carbon, like lampblack or charcoal.

Me, I'm waiting for when they put diamond particles into concrete mixtures or growing diamond bricks for building construction. Or growing diamonds as big as houses for industrial applications (Hard imagine for what though. Ultralight rocket motors?)

And that kids in Africa don't have to die for these artificially inflated lumps of carbon.
