How do I identify Waterford glass?

To identify Waterford glass, use its acid markings. You may need to use a magnifying glass while holding your piece up to the light to read them. Waterford began using acid marks in 1950 and has marked pieces with Gothic lettering, script word marks and its seahorse logo over the years. Older pieces usually had foil labels, which may have come off over the years. If your piece is unmarked, a certified appraiser or experienced antique dealer can help you determine if it's a Waterford. Find a wide range of Waterford glassware on 1stDibs.
