Rare 1970s Gorgeous purple Crystal glass drink set By Ivat. Made In Italy ~ Alexandrite glass

Super rare set of Italian 1970s purple glasses by Ivat.

Some wonderful information I’ve found online about the type of 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 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 set consists of 4 larger glasses, 5 slimmer and 1 pouring jug which is super rare. 

all in excellent condition. No chips at all.
