This year we were done Christmas shopping in August. See, we went on a geode dig in Utah this summer and decided to make the geodes our gifts. We included a printout with geological information about how the geodes formed. Plus we made a Christmas card with a photo collage of the dig.
I know everyone can't go on a geode dig, but you can still get a geode and break it open yourself. So here's a nice Break Your Own Geodes Kit. It comes with 12 geodes, which I think is a good amount in case you get a couple without nice crystals. By the way, did you know that if the geode feels light, it has more hollow space inside and therefore the crystals are likely to be larger.
