The title says it all. I found this stone, or crystal, in my yard, and I really like it. I like crystals and interesting rocks. But I would like to know what it is. My best guess, based on its shape, it that it is a geode that had been in running water. It definitely has crystal properties; it sparkles when looking at it from various angles, though the photos don't show it. I'm also guessing that it is smoky quartz. I'm not going to break it open, it is a great stone to hold and play with. It is slightly smaller than a big bic lighter.
Any geologists out there?
