Refinement Crystals are used for Refining player equipment, that is re-rolling the bonus stats assigned to any player-worn equipement (except white). They are are obtained from Recycling but can also be bought for (bound) balens.
As of Patch 8.0, equipment has been drastically overhauled; as a result, Lvl. 1 and 2 Refinement Crystals are no longer available. In addition, Lvl. 3 Crystals are now used to refine Novice and Novice (Legend) equipment, while Lvl. 4 Refinement Crystals are used to refine Advanced equipment. In addition, Elite Refinement Crystals are needed to refine Advanced (Equipment) and Knighthood Equipment, and Pure Refinement Crystals are needed to refine Artifacts and Halidoms.

Each kind of equip needs a different amount of these crystals to be refined according to their quality, and players can use Refinement Locks to protect some of the stats obtained to prevent losing them.
The refinement crystals can not be used to refine Sylph, Eudaemon or Mythic (red) equipment.
