You have to hack the game cause the rainbow gem was unfinished. so hacking is the only way to get it.
you cant.
Its a red gem
Yes and No. If you are wondering if there is a Super Sonic final boss, then yes. Complete all three stories to unlock the last story, then get to the end of the last story. Super Sonic, Super Shadow, and Super Silver will fight Solaris (Mephiles and Iblis combined). If you are wondering if you can get Super Sonic, Shadow, or Silver in the actual levels, then no (sadly). Ever since Sonic The Hedgehog 2, one had to collect all the Chaos Emeralds by beating special stages, and after that, one had to collect fifty rings in an actual level. In games like Sonic Adventure, Sonic Adventure 2, and Sonic '06, there are no special stages because the emeralds are used as plot devices in the story. If you know how to use the Gems/Custom Actions, then you'll find this interesting. SEGA had planned to include a special "Rainbow Gem" in the store, which allowed Sonic to go Super. However, '06 is an incomplete game, and the Gem's coding is hidden away in the game's files. It can be accessed through complicated hacking, but all it does is run through a super sonic transformation animation (without any pretty colors of effects). It is completely useless. If you want to try some hacking, many youtube users have made hacks that allow you to play as an in-level Super Hedgehog. Just search "Super Sonic 06." Hope this helps!
In Sonic Universe 50 we see Shard the worst for his battle against Metal Sonic and his Power Gem is cracked. However, while it is conclusive that he is offline/unconcious, it is not conclusive that he is dead. With that in mind, I say: No.
The rainbow gem is an incomplete gem that's supposed to let you transform into super sonic but it doesn't work. You can only get it by hacking.

try buying the sky gem again
you have to beat the game in all story modes and beat the extra boss
you cant.
First, Gain All S Rank's on Every single mission, Town stage, Act, and Boss stage's. Then, Collect every single Soleanna Medal (Silver One's).You will then gain another Gold medal. By now you Should have got every single Gold medal there is to get. Finally, Get All the Acheivement's, then buy it from the store! Cost: 30,000 Ring's.ORJust hack your Xbox 360 Console.
If you are referring to the yellow gem, it is purchasable only at the very end of Sonic's story. If you mean Super Sonic it is accessed during the ending sequence unlocked by beating all three story modes.
First,progress to a certain point in the game.Check the Soleana store often.Then get enough rings and buy it.Is it really that hard to figure out?
After you beat Aquatic Base, go to a computer or the store clerk. You have to buy them, and they are pretty expensive. So after you beat Sonic's story, you can replay the last part to get more money/rings.
Sonic the Next Gen is only available on Xbox360 and Playstation3.
