The onix you found was a very VERY rare one. It is called a shiny Pokemon and the star represents that it is a shiny Pokemon.
Onix evolves into Steelix when it is holding a Metal Coat and traded to someone else.

Unfortunately, you can't get an Onix in Pokemon Emerald. To have your own Onix, you need to trade it from FireRed or LeafGreen. Hope I helped :)
