How can you tell if a vase is Waterford crystal?

To tell if a vase is Waterford crystal, search for the maker's markings. Nearly all Waterford crystal vases feature an acid stamp on their bottoms or interiors. Because this marking has changed over the years, you can compare it to references available on trusted websites to get a rough idea of the age of your piece. Some Waterford vases also feature foil labels. However, these may fall off or be removed by previous owners. If you're still unsure if your vase is a Waterford, a certified appraiser or knowledgeable antique dealer can provide an expert opinion. Explore a selection of Waterford crystal wares on 1stDibs.
