Neodymium Glass

Neodymium glass (also known as Alexandrite glass), changes colour according to different lighting conditions. The glass appears lilac (or sometimes pink) in natural sunlight or yellow artificial light, and smokey blue in fluorescent/white light. This is due to the presence of Neodymium oxide (Nd²O³) in the glass. Glassware containing Neodymium was produced in several countries, including Scandinavia, Italy, and the Czech Republic. The shades of lilac, pink and blue can vary greatly depending on the glass mixture.
