Mana Crystals

Mana Crystal is the currency used by Mages across the human cities. In its raw form, they are harvested from places where the fabric between the Prime Material Plane  and the Elemental Planes are thin, allowing 'crystalised' shards of mana to grow. Where there are large volumes of Mana Crystals, there are almost always powerful Magical Beasts. While most mana crystals are non-elementally aligned, rare and precious specimens do exist as gems and precious stones. Examples include Jadeite, Citrine, Emerald, Zircon and Turquoise.
