Neodymium glass (sometimes referred to as Alexandrite glass), changes color according to different lighting conditions. The glass appears lilac (or sometimes pink) in natural sunlight or yellow incandescent light, and smoky blue in fluorescent/white light. This is due to the presence of Neodymium oxide within the glass. On its own, Neodymium is not UV Reactive. Some manufacturers added Selenium into their glass matrix which resulted in the bright pink fluorescent glow under UV light.
