Obsidian has been a great grounding tool for me in my spiritual endeavors. For some reason I find darker stones and crystals to be more effective to me personally while grounding -- maybe it's because they're less visually distracting to me than stones like sunstone or amazonite.
I've had great success with obsidian, Apache tears, hematite, snowflake obsidian, and blue tiger's eye. Snowflake obsidian is currently my favorite (right up there with hematite and normal obsidian). I find obsidian in whichever form to be grounding, calming, and stabilizing. I don't carry it around with me because mine's rather heavy, but it's still an amazing stone with wonderful capabilities.
