The Power Gems are small stones used to store elemental magic energy. The gems have been passed down from heroine to heroine for generation, but only to those deemed worthy of possessing such great power.

Jade Lightning of the Superheroine Squad possesses the Green Power Gem of elemental electricity and was originally a member of the Gem Angels, a team of international heroines each entrusted with a unique Power Gem.

The known Power Gems (and their elemental powers) include:

Diamond (Ice)
Ruby (Fire)
Onyx (Thunder)
Jade (Lightning)
Crystal (Wind)
Topaz (Earth)
Sapphire (Water)
