Treasures of the Earth - Rocks and Minerals Picture Book for Kids

My next book is a non fiction picture book for children.

Treasure of the Earth Rocks and Minerals Picture Book for Kids.

I think I have all the pictures I need. Just putting them in the CreateSpace
template and adding text commentary.

I created a couple covers. I am leaning towards the one with the quartz crystals.
The amethyst is good, but the background does not blend in with the cover color as well.
