8 Clean Emeralds.
There are ten stages for every type of crystals :
Crystals can be obtained from the mines, one mine for each type of raw crystal. They can be upgraded three times with the tiers of crystals going up as you upgrade, all the way to being able to obtain fine crystals. Mining takes gold and works just like growing food.
It takes 5 raw crystals to make a clean crystal, 5 clean crystals to make a pure crystal, and so on. This is done through the crafting station, and it takes platinum to fuse crystals.
