amethyst is strongly associated with the zodiac signs Aquarius and Pisces. However, many believe that amethyst is a universal gemstone whose calming and healing properties can benefit almost any sign, including Capricorn and Virgo. 
Spiritually, amethyst symbolizes calmness, spiritual protection, and wisdom. Its purple color is associated with the crown chakra, which connects to higher consciousness, intuition, and spiritual awareness. Ancient beliefs linked it to sobriety and clarity, and today it is used to promote inner peace, aid in meditation, and foster spiritual growth.
