Ethereal Gem

Ethereal Gems determine an item's particle effect. They can only be used on custom couriers of quality. Adding a Prismatic Gem to the same courier will alter the color of most effects.

Socketing
Ethereal Gems can only be extracted with a Master Artificer's Hammer. Doing so will destroy the courier. To socket an Ethereal Gem into an item, the new gem is placed "on top of" the old ethereal gem. This results in the old gem being destroyed.
