Our sun sign governs our fundamental nature and Cancer are caring, sensitive and generous. Cancer is the first Water Sign of the Zodiac, ruled by the Moon and symbolized by the crab. The healing crystals found below bring out the best qualities in Cancer. This list of crystals can also be useful when Cancer is located anywhere in a person’s astrological chart, including the Moon Sign (our emotional nature), Rising Sign (how we appear to other people), Mercury Sign (communication style), Venus Sign (love/feminine energy), Mars Sign (action/masculine energy), and Jupiter Sign (luck and abundance). The outer planets Saturn, Uranus and Neptune move more slowly through the zodiac and so affect our entire generation.
