How Are DIAMONDS Formed?

Diamonds are like super-hard, shiny rocks that take billions of years to grow deep underground.

Deep inside Earth, there’s a place called the mantle, it's like a thick layer of hot rock. In this hot, tight space, tiny pieces of carbon (the same stuff in pencils and your body) get squeezed super hard for a very long time.

Imagine being squished inside a giant hug that never lets go, that’s what the carbon feels like. Over millions of years, the pressure turns those tiny bits of carbon into something amazing: diamonds.

It's like how sugar can turn into rock candy if you let it sit in hot syrup for hours. The more time and pressure, the bigger and shinier the diamond gets.

Sometimes, Earth shakes or opens up, and these diamonds get pushed all the way up to the surface, just like when a bubble rises from the bottom of a soda can to the top. Then we dig them out and polish them so they sparkle in our rings and bracelets!
