This is a planet called 55 Cancri E I know name is catchy but what is amazing about this planets is that it is carbon heavy and it is extremely close to its parent star causing a lot of pressure on the planet which causes diamonds to form under its surface and there are a few images of what 55 Cancri E might look like

Also if it was possible to survive on the surface of the planet if you were to bring even the smallest amount possible you could completely destroy the diamond market making them completely worthless so this planet is best to be looked at from afar
