New geode for ice caves

Since the next Game Drop will be about ice Caves, i thought that a new type of geode which only spawn in ice Caves would be nice. In general i would like to see more Geodes, it ads to the Caves in my opinion.

The chrysocolla geode looks the most like turquoise which would be a new and unique color for Armor. 

If someone has another idea to add please feel free to share it in the comments, i think there could be more uses for this new crystal.
