Vivianite is a photosensitive crystal that will darken on exposure to light; when it is mined it is colourless, but darkens to a greeny blue. Large and well defined crystals are highly desirable, and they can also form in thin needle spray

 Vivianite enhances harmonious communication, making it easier to express oneself effectively and it stimulates compassion, which can be useful for individuals who wish to cultivate a greater sense of empathy towards others. It is also useful in emotional healing by helping to release trapped emotions. Vivianite has a revitalising effect on both the body and the mind, making it an excellent choice for anyone who needs a quick energy boost.
