Ametrine is a mixutre of purple amethyst and yellow citrine.
Amethyst is associated with the crown chakra and the spiritual realm, especially in relation to personal guides, angels and sources of expanded awareness.
Citrine's golden yellow color connects it to the solar plexus, to the center of personal will.
The meaning of ametrine is the alignment of the human being with the spiritual "higher self," bringing both into harmony. In practical terms, this means listening to and following intuitive feelings, encouraging creativity and new directions, and applying the pracitcal mind to make things happen.
