Alexandrite |
 |
Alexandrite glass changes colour according to different lighting. Glass appears lilac in natural sunlight, yellow in artificial light, and blue in flourescent/white light. This is due to the presence of Neodymium oxide (Nd²O³) in the glass. Glassware containing Neodymium was produced in several countries, and is particularily common in Czech glass. Technical name is Neodymium glass. (Source: 20th Century Glass) Shop for Alexandrite Glass |

Essentially, the glass was combined with copper or copper salts. When the glass melted and cooled, these mineral deposits would clump together to created a gold-flecked and shiny appearance on the glass. As is common with most glass, the glass itself had no color, but the additional minerals added could create varying colors like green and blue, although the most common color is a rich, ruddy brown.
