I absolutley love this post and, am a secretly big fan of all things geology!
Being a keen metal detectorist and physical history hunter, I find all kinds of interesting rocks when extracting my finds.
I hold the find in my hand which can sometimes be hundreds of years old! but the real treasure is those amazing rocks and minerals that are millions of years old and have developed into a thing of astounding beauty! I can't say I've ever found any Geodes or Quartz but I usually bring home some of the prettier rocks for my two children who love them.
Thanks again for a really informative and interesting post.
Cheers
