How do I identify a Murano glass fish?

To identify a Murano glass fish, first check the base for a maker's marking. Murano isn't one maker; it's an island located near Venice, Italy. Consequently, there isn't a single maker's mark that indicates a glass fish is Murano. However, you can research any maker's mark on the fish using trusted online resources to determine if the factory that produced it is based in Murano. Older Murano art glass may be completely unmarked, in which case experts generally recommend having a certified appraiser or knowledgeable dealer assist with the identification process.
