Geodes: Yes, geodes are trendy right now, but this is one instance where I’ve liked them since I was a child more because I was a nerd than a trendsetter. When I was young I collected rocks, and I had a purple geode I loved to just pick up and stare at. (I also had a rock tumbler, and I tried to grow crystals from a box a few times, too.) Now I have new geodes, and one set into a pendant that I found in a crappy rock shop in Barcelona for 3 Euros. I highly endorse decorating with them — plants are not the only things that can bring a natural element indoors.
