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).

UV sea glass, glows under UV black light, vaseline light green opaque sea glass ...UV glass was very popular around the 1930s and it is very likely that this piece of sea glass has been tumbled in the North Sea for the last 80 years or longer...

Seaham is on the East Coast of England, near Durham and Newcastle. During the Victorian times until 1890s fabulous art glass artisan manufacturing took place in Seaham. At the end of each day small amounts of coloured glass was melted together and given to the Sea... nowadays these end of day pieces of sea glass get washed ashore. Some pieces have shades of the same colour, others are rainbow coloured.
