What do you know about geodes? They're a great gift-store get at natural-history museums. Sliced thinly, they make for a mean coaster. Glued on unfashionable kitchen shoes, they're instantly chic. And they are probably something one of your mom's friends is really into for their healing properties, although you've never really pushed her on the issue. Today, there are many ways people are incorporating stones into their looks, lives and routines: From minimalist jewelry to cosmetic infusions, it seems like everyone, and not just the fringe/hippie set, is getting on board.

Whether you're using them as a catalyst for your spiritual awakening or just an accessory for the season, one thing's for sure: Geodes are stone-cold cool.
