A blue stone named for sodium, hiding glow-in-the-dark cousins and a habit of turning purple in sunlight.

means Sodalite is a deep-blue mineral, often streaked with white veins, prized as a semiprecious stone and named for the sodium locked inside its crystal structure.

from The name was coined in the early 19th century by joining 'soda' — the old word for sodium compounds, itself from the medieval Latin 'soda' (possibly via Arabic 'suwwad', a salt-rich plant burned for its ash) — with the Greek 'lithos', meaning 'stone'. So the word reads quite literally as 'sodium stone', a nod to the chemistry rather than the color.
