What are Saturn's rings made up of and where are they found?

Saturns rings are made up of really tiny particles and those particles are made up of mostly water ice and rocky material

The rings of Saturn are the most extensive ring system of any planet in the Solar System. They consist of countless small particles, ranging in size from micrometers to meters, that orbit about Saturn. The ring particles are made almost entirely of water ice, with a trace component of rocky material.
