Rainbow Zirconia

I must admit, I am impressed at the name you chose for this. I would not have expected you to know what a zirconia was.

Don't sound so shocked! I had to know a thing or two about rocks to help Shulk with gem crafting.

Ah, so it isn't simply because your head is as hard as one?

Oi! That's real low of you, Melia.

This skull's way harder than a zirconia - I'd rate it more like diamond!
