Decorative-arts specialist Lauren Anderson says authentic Murano glass must be made by artisans on the Venetian island of Murano, but signatures and labels alone are not reliable proof. Buyers should assess craftsmanship, research provenance and request detailed photos and condition information, especially for unsigned lighting.
A buying guide published by Veranda outlines how shoppers can assess whether a piece of glass is authentic Murano or merely made in a similar style, citing advice from Lauren Anderson, decorative-arts director at STAIR Galleries. Anderson says buyers should look beyond stickers and signatures to examine workmanship, ask about a piece’s history and check its condition before purchasing.
In Anderson’s account, the defining point is where the glass was made: to qualify as Murano glass, it must be created by artisans on the island of Murano in the Venetian Lagoon. “Murano-style” describes work made elsewhere using comparable materials or techniques; resemblance does not establish that an object was made on the island or carries the same provenance.
Handmade details can offer clues. The guide says a piece may have a pontil mark—a polished or concave scar left where it was detached from a glass-blowing rod—and slight variations associated with hand production. Anderson advises taking another look if a piece feels clunky, appears poorly designed or has visible imperfections. She says well-made layered glass can remain relatively lightweight, even when its decoration uses several layers or metallic materials.
Those signs are not a standalone authentication test. Anderson recommends comparing a signature with examples of the artist’s known work and asking the seller for provenance, or information about the object’s origins and ownership. Labels and signatures can be copied, she warns. For online listings, the guide recommends requesting photos from all sides, including the top and base, and asking directly about internal cracks or other damage.
Checks Before You Buy
Knowing the difference between island-made glass and an imitation matters to buyers weighing authenticity, condition and price. A piece can look like Murano work without having been made there, so appearance alone may not support claims about its maker or origin. Damage can also affect value: Anderson says glass may lose substantial value if it has damage, including internal cracks.
The advice is particularly relevant to lighting. Anderson says Murano glass chandeliers and sconces can be difficult to identify because they are generally unsigned, while makers elsewhere copy popular traditional designs. For a high-cost purchase, a seller’s account of where a fixture came from and how it was acquired may be more useful than a label by itself. The guide does not offer a formal certification process or a guarantee that any single visual clue proves authenticity.

Murano’s Island-Making Tradition
Murano is an island cluster in the northern Venetian Lagoon with a long history of glass production. The guide traces that role to 1291, when Venice’s Doge Pietro Gradenigo ordered glass furnaces moved to the island because of fire risks to the city’s wooden buildings. The island became a centre of Venetian glassmaking.
Anderson describes Murano glass not as one brand but as a tradition involving many artisans. She compares the geographical link to Champagne: the name refers to a place of production, while “Murano-style” can refer to similar work made elsewhere. The guide says wider availability through retailers, flea markets and antique shops has made it easier to encounter pieces presented in the style, increasing the need for buyers to check claims carefully.
““As with any popular work of art, imitations are a possibility.””

Limits of Visual Clues
The guide does not establish a single feature that can conclusively authenticate every piece. Pontil marks, signatures, stickers and visual quality can inform an assessment, but the source says signatures and stickers may be copied, and it recommends comparing signatures with known examples. It does not identify a certification authority or describe laboratory testing.
For unsigned lighting and pieces with limited sale records, the maker and exact place of production may remain difficult to establish. The source also does not provide market prices, a method for estimating value, or independent authentication of any specific object. Buyers may need additional expert review where the evidence from the seller and the object itself is incomplete.
Questions for Sellers and Dealers
Before buying, shoppers can ask the vendor about the object’s origin, ownership history, condition and maker, then request clear images of the base, top and sides. Anderson also recommends seeking reputable dealers who can explain their assessment and checking auction houses, where pieces may come from private collections. The guide does not identify a particular upcoming event or further reporting milestone; the next step for a prospective buyer is to verify the claims behind the specific item.
Key Questions
What makes glass authentic Murano glass?
According to Anderson, it must be made by artisans on the island of Murano in Italy. A similar design made elsewhere may be called Murano-style, but that does not establish island origin.
Does a Murano sticker or signature prove authenticity?
No. Anderson cautions that stickers and signatures can be copied. Buyers should compare signatures with known examples and ask about the piece’s provenance.
What is a pontil mark?
A pontil mark is a polished or concave scar that can remain where a hand-blown piece was detached from its glass-blowing rod. It may be a clue to how an object was made, but the guide does not present it as proof of authenticity on its own.
What should I request when buying Murano glass online?
Ask for photographs from all sides, including the top and base, and ask the seller about origins and damage such as internal cracks. The guide says damage can reduce a glass object’s value.
Why are Murano glass lights harder to identify?
Anderson says lighting pieces are generally unsigned, and makers outside Venice copy sought-after traditional styles. Buyers should ask where a fixture came from and how the seller acquired it.
