You're welcome.

It's okay that you have crystals, as long as you don't use them for any spiritual purpose. I would also suggest not placing any meaning in them, because that comes from new age and it is false. God never gave crystals any spiritual purpose, they aren't good or evil, they don't have any "energy" in them (which you know), they are just minerals. Crystals in themselves do not open doors to the devil, and we shouldn't fear them like many do (fear opens doors to the devil), as if the devil created them somehow (which is idolatry, and it also opens doors to the devil). I like geodes, they are really cool.

God has created so much beauty in nature. As long as we don't worship Creation itself, it isn't idolatry to enjoy it. I am filled with awe when I study nature or science, or just look at an awesome rock or flower or butterfly or animals playing in the woods. God created all of that! He created the animals for us, and I would assume that He created beautiful sunrises for us as well, and He blesses the Earth with rain. To show His Glory so we can enjoy it.

Psalms 19:1 As long as we don't worship creation, but give all praise to God, then we aren't sinning.
