The Protection & Grounding edit brings the two together on purpose: stones that keep the day's negativity off you, and stones that keep you planted while they do it. Black tourmaline, hematite, black obsidian, smoky quartz, black onyx, sulemani hakik, red jasper and shungite, dark, earthy, root-chakra leaning, and easy to wear whether you want a boundary or a bit of steadiness.
How to use them for negativity
For a boundary you carry all day, wear black tourmaline or hematite on the wrist, or keep a pocket tumble on you. Black obsidian and sulemani hakik are worn to deflect other people's energy. Smoky quartz and red jasper lean grounding, they help you feel settled rather than shielded. Layer a protection stone with a grounding one and you get both at once.
