Ethereal Gem

Ethereal Gems give the item an Unusual particle effect. As of now they can only be used on Unusual couriers. Particle effect colors can be further altered with a Prismatic Gem. It is unknown if Valve will decide to let Ethereal gems work on non-unusual couriers but many have said an Artificer's Brand is required.
