Lapis is a Enhancer Filter Crystal. Enhancers are minerals and crystals with internal crystal lattices of perfect cubic symmetry and internal harmony. They can focus and enhance our energy on the feelings of improvements we desire and help turn them to the thoughts that will produce the actions we need to improve.
Lapis, with its earth power of a Filter, is used to keep negative energy away from us. When we want help to see the best in others, to give others the benefit of the doubt, to see the good side of something, use a Lapis Lazuli.
It is too easy in life to see the glass half empty, the child as a poor student, or the spouse as a slob. Filters, like Lapis, help us see the glass half full, the child as a loving, well-meaning young lady, and the spouse as an excellent provider, devoted to his family.
Dark Blue Lapis is for enhancing respect and compassion in ourselves. Dark blue crystals teach us humanity, discretion, and honor. They help us act more charitably, and focus our efforts on service to others. They teach us grace, sensitivity to the needs of others, and tenderness in our dealings.
Blue is the color of the true birthstones of those born as the world awaits the vernal equinox and spring (February 19–March 19). This is a time when new life is about to burst forth, a time of faith and trust.
Blue Lapis Lazuli is associated with the Throat Chakra. The throat chakra is the voice of the body. It is a pressure valve that allows the energy from the other chakra to be expressed. If it is out of balance or blocked it can affect the health of the other chakras.
When it is in balance we can express what we think and what we feel. We can communicate our ideas, beliefs, and emotions. When the throat chakra is in balance and open, we can bring our personal truth out into the world.
