Lapis Lazuli is great relieving anger and negative thoughts - these could be about yourself or feelings you have for others. A great stone for those who wish to call in more self-awareness, self-confidence, self-knowledge, peace, harmony, compassion, intellectual problem solving + creating new ideas.
It is also said to protect you from psychic attacks.
The chakra stones are for rebalancing the chakras. They help you to release negativity which results in emotional release - moving those energies through and out of your body so that you don’t hold onto and store them which would result in poor health.
