Energymuse.com tells us that, "Amethyst is thought of mostly as a protective stone. As it is linked to the crown chakra, it is helpful in purifying the mind and clearing it of negative thoughts. This includes the negativity of stress and anxiety, which is why many meditate with amethyst so as to rid themselves of that darkness. Amethyst healing properties are especially useful in regards to work-related stress, because the stone is also associated with abundance; therefore relieving stress while emanating prosperity. The amethyst properties which facilitate intuition and communication can also be applied to increased work effectiveness."
