3.5 inches tall Fluorite is known as the "Genius Stone" for boosting mental clarity, focus, and decision-making, while also absorbing negativity and promoting balance, making it great for study or work. It's prized in crystal healing for its calming, protective, and harmonizing effects, aligning chakras (especially with its varied colors: purple for intuition, blue for communication, green for heart) to support emotional and spiritual growth.
