How do you date Waterford crystal?

To date Waterford crystal, look for the maker's mark. Since 1950, the brand has placed markings on discreet areas of its pieces. By comparing the mark on your crystal to images shared by trusted online sources, you can get a rough idea of how old your piece is. Alternatively, you can have a certified appraiser or experienced antiques dealer evaluate your piece. On 1stDibs, explore a wide range of Waterford crystal.
