Alexandrite Neodymium Crystal Ashtray Solid 800 Silver Overlay

A large Heavy alexandrite neodymium lavender glass ashtray with silver 800 overlay. Measures 15 cms x 15 cms x 4.5 cms.
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 smoky 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.
This ashtray was sourced in Italy and dates from circa 1970s. Condition is as seen, no chips or cracks to glass, some wear to silver overlay, 800 silver hallmark is stamped on silver.
