The frequency of Lapis Lazuli connects to the throat and third eye chakras. The energy of Lapis Lazuli helps one to connect to the higher dimensions to bring forth knowledge and understanding to allow one to move forward. It helps one to discover any belief patterns or blockages that are preventing one from moving forward in this lifetime.
It's connection to the throat chakra allows one to both discern and speak truths, and thus communicate those truths to others. The connection to the third eye will help to stimulate one's inner vision to bring forth guidance and knowledge in a visual manner. Lapis Lazuli can help stimulate one's memory and thus aid with one's learning skills.
