Anyone hidden mana crystal resource image name?

[Dougletron]

You know how theres that hidden blue crystal image used as a possible resource instead of gold or lumber, anyone know the name of it?

Edit:

I need the non-tooltip icon of that image, did they make one or will i have to make it myself? I just like to save map space if i can.

So i guess im asking for the path of the image if it exists.
