How do you identify Orrefors?

To identify Orrefors, look for a signature on the bottom of the piece. All pieces made after 1930 typically show the Orrefors name, a serial number and the word "Graal," which refers to the technique used to produce the maker's crystalware. You may also see the word "Sweden" or "Suède" on some pieces. Prior to 1947, Orrefors also indicated the year of production under the signature. If you're still uncertain of the authenticity, consider using the services of a certified appraiser. Find a variety of Orrefors pieces on 1stDibs.
