Plants and Crystals

JennyFunk

I know I've seen a thread here before about what crystals you can put in your plants...but I'm wondering what type of stone I can sit on top of moss inside an enclosed terrarium, just for looks sake at least (as in not to promote growth specifically). This canister will have tons of moisture in it and I dont want to break down the crystal or anything. Suggestions? criteria = withstand humidity and slight bacteria in soil and stand out through glass sitting on top of moss.

Most quartz, agate or jasper stones should be fine.
