Restless? Try aragonite!
Aragonite is a stone of grounding, emotional stability, and deepening environmental connection. Known as a "stabilizing stone," it is often employed to reduce stress, anger, and anxiety while promoting patience and mental clarity. It is commonly used for root chakra healing to foster security and to enhance patience and acceptance. Aragonite is also a great stone for meditation - just look at those calming brown stripes and let the energies of aragonite carry you to a calmer state of mind.
Can dissolve in water, so it is best to cleanse with sunlight or moonlight.
