How do I identify my crystal manufacturer?

To identify your crystal manufacturer, look for the maker's markings, usually found on the bottom, back or inside of pieces. One way to use the mark is to take a photograph of it and then perform a reverse image search. You can also enter a description into a search engine and then consult trusted online resources to determine who made your piece. If you can't find a maker's mark or need further assistance, enlist the help of a certified appraiser or knowledgeable antiques dealer. On 1stDibs, find a wide range of crystal wares.
