How does sodalite glow?

Sodalite can exhibit a glow under ultraviolet (UV) light due to the presence of certain minerals and impurities within its structure. When exposed to UV light, some of these impurities can fluoresce, emitting visible light in response. This phenomenon is often seen in specific varieties of sodalite, enhancing its visual appeal and making it popular in decorative applications. However, the glow is not inherent to all sodalite stones and depends on their specific mineral composition.
