If you are taking the crystal piece to an appraiser, it is best to send along prints or digital images of the pieces before showing the appraiser the actual piece. Some appraisers like to begin the process by looking over these photos before seeing the piece. It is also possible for individuals to view examples of distinguishing features of crystal pieces on some appraiser websites. As an alternative, an individual can visit a public library or bookstore to look at reference guides that show these identifying features.
In most cases, the manufacturer's mark is on the bottom of the stem of each crystal piece. Most crystal has an etching, sticker or symbol that serves as the marker. If the symbol is difficult to see, an individual may want to shine a light on the bottom of the stem to make it easier to see. Using a magnifying glass may also help to make the emblem more visible. Before buying new antique crystal, experts also recommend that individuals learn some of the most well-known markers, especially from manufacturers such as Lenox and Fostoria.Learn more about Tableware
