This Bud Vase was made with Neodymium glass or known as Alexandrite glass. The glass appears lilac or smoky blue depending on lighting (see pictures).
Dimensiond are 6" x 2 1/2" with a no signature on flat polished base, I'm believing it is Muranise by Cesare Toso because of a similar vase I found for sale that is 2 smaller with a label attached. We try to describe each item as well as we can but please be sure to view our photos for an accurate description.
