# Refinement (Crystals)

Only Refined Genotype Crystals can be used as ingredients for Alchemy (crystal-based crafting). Unrefined crystals cannot. Unrefined crystals must first be refined via a Habitat's Laboratory, transforming them into tokenized game assets with direct utility in the form of Refined Crystals; only then can they be used by the player for gameplay.

Requirements for crystal refinement:

* Unrefined crystal
* KI (10 required per crystal)
* Habitat Laboratory

An unrefined crystal is not a tokenized asset until it is minted and refined. Refined Genotype Crystals can be traded between players on the marketplace.
