Sodalite is a dark blue gemstone that sometimes has yellow lines due to the sulphur content throughout. It can be confused with Lapis Lazuli and was used by the Ancient Egyptians. Use warm soapy water to clean Sodalite, not ultrasonic cleaners. Sodalite is said to boost the immune system and cleanse ones’ internal organs. It’s found in Namibia, Brazil, Canada, Russia and the U.S.
