How can you tell if glass is Steuben?

To tell if glass is Steuben, look for the maker's mark. Many pieces feature a fleur-de-lis logo as well as the Steuben name written in capital block letters. However, Steuben markings did evolve over the years, so it's a good idea to compare the mark on your piece to images of logos and wordmarks shown on trusted online resources. If you need help with identification, use the services of a certified appraiser or knowledgeable antique dealer. Find a variety of Steuben glass on 1stDibs.
