Neodymium? Colour changing glass also called Alexandrite was first discovered in 1885. The production process was perfected in the 1920's in England and Germany and became really popular. Neodymium glass looks purple in daylight and changes to a blue grey under fluorescent light. Derived from the Greek words 'neos' (new) and 'didymos' (twin).
