Sodalite

Sodalite is a deep blue mineral found in igneous, metamorphic and sedimentary rocks. It's known for its beauty and potential energetic qualities.  
Geologically, it's a tectosilicate, a category of minerals with a framework structure. Sodalite's hardness makes it suitable for jewellery and carvings. 
Spiritually, Sodalite is associated with truth, communication and inner peace. Its blue colour is linked to tranquility and clear thinking. Some believe it can boost self-esteem, creativity, and logic. It's often linked to the throat chakra, supposedly promoting clear communication. 
Sodalite is used in meditation and carried for emotional balance. It's said to be a gentle stone, working slowly to dispel negativity and anxieties.
