— Description, Sonic the Hedgehog (2006)[1]

The Red Gem (レッドジェム Reddo Jemu?) is an optional Level Up Item for Sonic the Hedgehog in Sonic the Hedgehog (2006) and is one of the seven customized Gems that can be obtained in the game.


The Red Gem is a red emerald cut gem, similar in appearance to a Sol Emerald, that can be equipped on Sonic's Custom Shoes. When used, it allows Sonic to perform Slow, which slows down time.

While having set Sonic's Custom Shoes to utilize the Red Gem's ability, the Red Gem changes their appearance into a red pair of shoes resembling Sonic's 2G Hi-Speed Shoes.


The Red Gem becomes available at the local Shop, once the player clears Tails' version of Wave Ocean in the main story. It can then be bought for 5,000 Rings.


  • In addition to slowing down objects and enemies, the Red Gem also slows the timer, making it much easier to get S Ranks in Acts.
