- "Not only is it wrong to go against the laws of nature, such as prolonging the life of those who should die... The ÄRM 'Gem Life' is considered a forbidden ÄRM because the engraving process also involves playing with the souls of the dead."
- ―Iffy Pendleton
Gem Life (ジェムライフ, Jemu Raifu) is a Holy ÄRM that is listed in Caldea's Pandora Records. It has the power to negate life-threatening diseases so long as it's worn. It is banned because it contains negative power born from the souls of the dead.
