Crystal Trees are a type of tree in the Aether II: Genesis of the Void. They often generate on small islands of Holystone and Aether Dirt by themselves. They give off a particle effect similar to Golden Oaks, but light blue. Breaking this tree's Crystal Fruit leaves will always drop a White Apple that stops the symptoms of poison.
These trees have since been changed and are now known as Purple Skyroot Trees.
