Why do diamonds sparkle? When light enters the dense matrix of a diamond, it gets bogged down. The light photon becomes trapped in a maze, and it takes a lot of pinging back and forth amidst a thicket of carbon atoms in order to find an exit. This action is what gives diamonds their sparkle. They actually change the way light behaves.
The rocks are alive! Ok, not really. But scientists do say that more than half of all the mineral species on Earth owe their existence to life. Back when the earth was young, it had only around 250 or so different minerals. But as life transformed the planet, it also changed the rocks. New elements mixed together, and gave way for the creation of new minerals, such as rhodonite, turquoise, aragonite, calcite, or hazenite, among others.
