This is an attractive piece of glass made in purple, with blue outlining at the bottom, cased within clear glass. I have not been able to positively identify the maker, but I believe that it is of Murano origin - if not Murano, it is still a quality piece of glass. The underside is hand polished as quality glass of the period was finished.
It measures 8 by 10 across its top opening and has a height of 6 1/4.

It is in very good condition - a few light scratches on the underside due to surface contact.

This is a beautiful piece of glass - lovely colours!
