Nobody knows exactly.
Normally, planetary rings are made up of rocks caused by impacts between planets, moons and asteroids.
However, Neptune is not a solid planet, so there is nothing for other space objects to impact on. Also, Neptune's rings are very faint and incredibly difficult to see.
Therefore astronomers think the rings of Neptune are made of micrometre dust (dust the size of a millionth of a metre) and ice particles.
Neptune has 13 rings and they are made up of dust particles
No they were discovered in 1968 by Edward Guinan
Neptune's rings are believed to be made up of fragments of dust and ice, as well as small rocks and boulders. They are darker in color compared to Saturn's rings and are thought to contain organic material. Additionally, Neptune's rings are relatively young in astronomical terms, likely formed from the breakup of one or more of its moons.

Yes, Voyager 2 did discover Neptune's rings during its flyby of the planet in 1989. The spacecraft's observations revealed several faint rings around Neptune, which were later named Galle, Le Verrier, Lassell, Arago, and Adams.
Neptunes rings are made up out of gas.
