Decorative-arts specialist Lauren Anderson says genuine Murano glass is made by artisans on the island of Murano, Italy, but the term is also used for glass made elsewhere in a similar style. Handwork, a piece’s history, its condition and a seller’s documentation can help buyers assess authenticity; no single visual clue guarantees it.
Veranda has published advice from Lauren Anderson, decorative-arts director at STAIR Galleries, on how buyers can assess whether a piece of Murano glass is authentic. Anderson says the designation refers to glass made by artisans on Murano, Italy, while similar-looking work made elsewhere is more accurately described as Murano-style—a distinction that can affect a piece’s provenance and value.
Anderson advises buyers to examine how a piece is made, but not to treat any single feature as proof. Many Murano objects are hand-blown and hand-shaped, and may show slight variations associated with handwork. A pontil mark—a polished or concave scar left where the object was detached from a glass-blowing rod—can be one clue. Its presence alone, however, does not establish where or by whom the glass was made.
Workmanship and weight also matter in Anderson’s assessment. She says finely made pieces can combine layers and vivid patterns while remaining relatively lightweight. A clunky feel, poor design or obvious flaws should prompt a buyer to seek more information. At the same time, a piece that looks exceptionally uniform or machine-made warrants further research; handmade variation is a clue, not a guarantee of authenticity.
Anderson recommends asking for a piece’s provenance and comparing any signature with known examples by the artist. She warns that labels, stickers and signatures can be copied, so they should not be relied on by themselves. For online purchases, she advises requesting photographs of the object from all sides, including its top and base, and asking directly about internal cracks or other damage.
Authenticity Can Affect Value
The guidance matters to collectors because Murano-style glass can resemble work made on the island without sharing its origin. Buyers who mistake resemblance for provenance may pay for a piece on the basis of an attribution that has not been established. Anderson’s advice is to treat the seller’s account, documentation and workmanship as evidence to examine together, rather than assuming a decorative appearance or label confirms authenticity.
Condition also has financial consequences. Anderson says glass can lose value if damaged, making questions about cracks and close inspection of photographs relevant even when a seller describes an item as authentic. This is especially pertinent to lighting: Anderson says Murano chandeliers and sconces are often unsigned, and traditional designs are copied by makers outside Venice. Buyers may have to rely more heavily on documented history and the seller’s answers for those pieces.

Murano Means a Place of Making
Murano is an island in the Venetian Lagoon with a long glassmaking tradition. The source report recounts that in 1291, Venice’s Doge Pietro Gradenigo ordered the city’s glass furnaces moved to Murano because of fire risks to Venice’s wooden buildings. The island subsequently became a center of Venetian glassmaking.
Anderson describes Murano glass as a collective tradition rather than one brand, comparing its geographic meaning to Champagne’s connection with its region in France. Under that definition, where the glass was made is central: a similar technique or appearance does not by itself make a piece Murano glass. The report offers buying guidance from one expert, not an independent authentication of any particular object.
““Murano is also used to refer to a ‘style’ of glass which is emulated by artists outside of pieces created on the island of Murano.””
— Lauren Anderson, decorative-arts director at STAIR Galleries
What Visual Clues Cannot Prove
The report does not provide a definitive test, authentication service or checklist that can verify every piece. Features such as a pontil mark, layered color, light weight or a signature may help guide research, but the source does not say any one feature proves an object was made on Murano. It also does not identify a specific item whose authenticity has been disputed.
Provenance may be incomplete, and signatures and stickers can be copied. The report does not specify what documentation is sufficient in every case, how to resolve conflicting seller accounts, or how to estimate value. Anderson’s recommendations are expert buying guidance; authentication and valuation of an individual object remain dependent on its evidence and condition.
Questions to Ask Before Buying
Anderson recommends buying through a reputable dealer or another source able to discuss the craft, and asking about the object’s condition, origins and how the vendor acquired it. Online, request clear photographs of the top, base and all sides, then ask whether there are internal cracks or other damage. Compare any claimed maker’s signature with known examples, and seek additional advice if the object’s weight, finish or workmanship gives you pause.
The source report also points to local and online auction houses as possible places to find Murano glass, including pieces from private collections. Buyers should still ask for the available history and condition details; an auction listing or collection attribution does not, by itself, settle authenticity.
Key Questions
What does Murano glass mean?
Murano glass refers to glass made by artisans on the island of Murano in Italy. Similar glass made elsewhere may be described as Murano-style, according to decorative-arts specialist Lauren Anderson.
Does a pontil mark prove a piece is authentic?
No. A pontil mark is a scar left when a piece is detached from a glass-blowing rod, and it can be a clue to handwork. The report does not present it as proof of Murano origin.
Can a signature or sticker confirm authenticity?
Not by itself. Anderson warns that signatures and stickers can be copied. She recommends comparing signatures with known examples and checking the piece’s provenance and workmanship.
What should I request when buying Murano glass online?
Ask for photographs of the object from all sides, including the top and base. Ask about its history and whether it has internal cracks or other damage, which can affect value.
Are Murano chandeliers and sconces harder to authenticate?
Anderson says Murano glass lighting can be difficult to identify because these pieces are generally unsigned and similar styles are made elsewhere. She recommends asking the seller where the piece came from and how they acquired it.
