Gem of Eternal Density (ProjectE)

The Gem of Eternal Density is a tool added by ProjectE. It is used to turn. It does this only while active and on the user's hotbar. If placed in an Energy Condenser, Alchemy Bag, or Alchemical Chest it will convert 10 items per second.

It can be used to create the Black Hole Band as well as the Gem Leggings.
