Yes, both the Swirling Sphere of Color and the Shattered Emerald of Corruption can be MQed. Both are turned in to NPCs each with a type of sword you will have in your inventory. Have the person with the sphere/emerald turn that in first and then turn in the sword which you possess.

Mairee Silentone gives you the "Dwarven Smiths Hammer," which identifies as Hammer of an ancient dwarf.
Head to Island Four of the Plane of Sky and kill an essence tamer which drops the Swirling Sphere of Color.
Give Mairee Silentone the Hammer and the Swirling Sphere of Color.

Give Xanuusus the Refined Mithril Blade and the Shattered Emerald of Corruption.
I also MQed both of these items and was not in a group either time, FTR.
