Decorative-arts specialist Lauren Anderson says authentic Murano glass is made by artisans on Italy’s Murano islands, but labels, signatures and stickers alone do not prove origin. She recommends examining craftsmanship, checking provenance and asking sellers for detailed photos and condition information.
A buying guide published by Veranda outlines how shoppers can assess Murano glass authenticity, with Lauren Anderson, decorative-arts director at STAIR Galleries, advising buyers to look beyond labels and examine craftsmanship, provenance and condition. The distinction matters because “Murano-style” glass can imitate the look without having been made on the Venetian island associated with the craft.
Anderson’s central distinction is about where a piece was made: to qualify as Murano glass, it must be created by artisans on Murano, an island group in the Venetian Lagoon. The term describes a tradition and community of makers, not one company or brand. Glass made elsewhere using similar materials or techniques may be described as “Murano-style,” but that wording does not establish Murano origin.
Buyers can examine a piece for signs of handwork. Many hand-blown objects have a pontil mark—a polished or concave scar left where the glass was detached from its blowing rod—and may show slight variations consistent with handmade production. Anderson cautions that both machine-like uniformity and poor workmanship warrant closer investigation: a piece that feels clunky, is badly designed or has conspicuous flaws may not be a convincing example of skilled Murano work.
Weight and layered decoration can offer additional clues, but they are not proof by themselves. Anderson says finely made pieces can remain relatively lightweight even when they have multiple layers, which may include fused gold, silver or platinum. She advises buyers to compare signatures with documented examples by the named artist and to seek a credible account of the object’s history. Signatures and stickers can be copied, so a mark alone cannot verify origin.
How Buyers Can Reduce Risk
For shoppers, the practical risk is paying an authentic-Murano price for a piece whose origin is only described as similar in style. Anderson’s advice points to a combined assessment rather than a single tell: workmanship, the object’s physical details, supporting documentation and the seller’s account should be considered together. None of the visual clues described in the guide, on its own, confirms where a glass object was made.
The stakes may be higher for lighting and older pieces. Anderson says Murano glass lighting can be difficult to identify because such pieces are generally unsigned and makers outside Venice copy sought-after traditional designs. Damage also affects value: the guide advises buyers to ask about internal cracks and other condition issues before committing to a purchase.
That makes basic due diligence useful whether a shopper is buying online, at an antiques shop or through an auction. Requesting photographs from several angles and asking direct questions about origin and condition can help reveal what a listing does—and does not—support. If the seller cannot substantiate a claim, the buyer may have to treat the attribution as uncertain rather than verified.

Murano’s Place in Glassmaking
Murano refers to islands in the northern Venetian Lagoon. The Veranda guide says glass furnaces were moved there in 1291, after Doge Pietro Gradenigo ordered their relocation because of fire risks to Venice’s wooden buildings. The island subsequently became a center of Venetian glassmaking and remains associated with a long-running craft tradition.
Anderson describes Murano glass as a collective tradition involving many artisans, rather than a single maker. The guide compares the geographical designation with Champagne: the name refers to a place and its established production tradition. That helps explain why a similar-looking object made elsewhere can be “Murano-style” without being Murano glass.
The guide also notes that Murano objects are now found through retailers, flea markets and antique shops, not only by traveling to Venice. Wider availability gives buyers more ways to encounter the work, while also making it more important to distinguish a documented origin from a description based on appearance.
““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 Appearance Cannot Verify
The guide does not provide a definitive test that can authenticate every object. A pontil mark, a signature, a sticker, layered color or a light feel may inform an assessment, but the source does not say any one feature conclusively establishes origin. Anderson instead recommends considering quality alongside provenance and comparing an object with known examples.
The supplied report also does not identify a formal certification system, list independent authentication services, or give a method for resolving disputed attributions. It does not provide prices or quantify how frequently imitations are encountered. Buyers should not treat a seller’s description, or the visual clues alone, as conclusive documentation.
Some objects, particularly lighting, may lack signatures, according to Anderson. In those cases the maker and history can be harder to establish. The guide recommends asking where the seller acquired the item, but it does not say that a seller’s answer by itself verifies the account.
Questions to Ask Before Buying
Before purchasing, ask the seller where the piece came from, whether its maker is known, what documentation supports the attribution and whether it has been repaired or damaged. For online listings, request clear images of all sides, including the top and base, and ask specifically about internal cracks if photographs do not show the interior clearly.
Anderson recommends seeking reputable dealers who can discuss the craft and answer questions about condition and provenance. She also points buyers toward local and online auction houses as possible places to find pieces, including objects from private collections. The source does not identify particular dealers or upcoming sales, so buyers will need to evaluate each seller and listing individually.
Key Questions
What makes glass authentic Murano glass?
According to Lauren Anderson, it must be made by artisans on the island of Murano in Italy. Similar-looking glass produced elsewhere may be called “Murano-style,” but that does not make it Murano glass.
Does a pontil mark prove a piece is authentic?
No. The guide describes a pontil mark as a common sign of hand production, but it does not present the mark as definitive proof of Murano origin. Buyers should also examine quality and seek provenance or other supporting information.
Can a Murano sticker or signature confirm authenticity?
Not by itself. Anderson warns that signatures and stickers can be copied. She recommends comparing a signature with known examples and asking about the object’s history.
What should I ask before buying Murano glass online?
Ask for the piece’s provenance and condition, including whether it has internal cracks or other damage. Request photos from all sides, including the top and base, so you can inspect the glass surface and construction.
