I inherited my grandmother's curio cabinet. I gave it a good cleaning and put all my rocks and books on it.
The big rock on the wooden branches is a geode. The baseball sized rock in front of it is a fluorite crystal. Fluorite crystal are protection from Evil and bad things in your life. The rest are quartz, iron, a little quartz/granite geode, and pyrite (fool's gold).
If I only had my Grandmother's rock collection. She had it all from volcanic ash to petrified wood.
