Detecting Fakes in Person
Ask to see the holograph sticker which has a number on it, denoting the furnace the glass came from. Authentic Murano glass pieces have that sticker.
Ask for a certificate of authenticity showing the date of production and artists' information
Check for minuscule nicks in the surface or the glass. Real Murano glass will have no imperfections whatsoever.
Detecting Fakes Over the Internet
Examine the seller's other products. If the seller is selling the same piece over and over again, they're surely fake. Murano artisans do not make the same piece over and over.
Find out where the glass was made. Genuine Murano glass is made only in Murano, Italy. No exceptions,
Check their shipping costs. Some sellers on the Internet will sell their products for $1 to $5 and make most of their profits in high shipping costs: $20 to $30.
