I was curious too Xeven, so I did a little searching on the net:
* What are Saturn's rings made of?
The rings are made of dusty water ice, which range in size from boulders to sand grains. Saturn's gravitational field constantly disrupts these
ice chunks, keeping them spread out and preventing them from combining to form a moon.

Hers is another interesting site about the color of Saturn's rings. Kind of an old article though:
Most people don't know that Saturn's rings aren't white but have a faint salmon color, which hints that a few percent of complex organic molecules
are mixed in with the water ice the rings are mostly made of," Cuzzi said.
Saturn's seven small icy moons don't have such a reddish color, but many icy objects in the frozen reaches of the outer solar system do, he
explained. This leads scientists to suspect that, unlike the moons, the rings were formed from an outer solar system object.
This object, they think, careened too close to Saturn and -- like comet Shoemaker-Levy 9 in 1994 -- was torn apart by the massive planet's gravity,
leaving a trail of debris.
This info I got from this
website
This gives some info on Saturn's ring structure and it's divisions:
Saturn's ring system is divided up into 7 major divisions with alphabetic designators in the order of discovery. From the innermost ring to the
outermost ring the designators are D, C, B, A, F, G and E. Each major division is further subdivided into thousands of individual ringlets. The F and
G rings are very thin and difficult to see while the A, B, and C rings are broad and quite visible. Between the A and B rings is a gap called the
Cassini division named after Giovanni Cassini who discovered the Gap in 1676. Between the A and F rings lies the Keeler (Encke) gap.

Hope this answers some of your questions on Saturn's rings.
