What scientists found trapped in a diamond: a type of ice not known on Earth
Trapped in the rigid structure of diamonds formed deep in the Earth's crust, scientists have discovered a form of water ice that was not previously known to occur naturally on our planet.

Ice-VII is about one and a half times as dense as the regular ice
