If the holder uses a damage-dealing Ice-type move, then the holder consumes this item and the power of that move is increased by 50%. One-time use.
In single battles, Ice Gem is not typically a useful item, unfortunately. While the one-time boost to Ice-type attacks is nice, most Pokemon using Ice-type attacks would rather have the more reliable power of Life Orb or Choice items.
Typically Gems are more valuable in the VGC and similar environments, and Ice Gem is often used here to boost the power of Ice-type attacks such as Icicle Crash from Pokemon such as Mamoswine. The one-time power boost can come in very useful in such a fast-paced metagame, especially as it comes without any drawbacks. In addition, it can be of great use to hail-based offensive teams, in order to boost the power of Blizzard from Pokemon such as Rotom-F, Froslass, and Lapras.
