How to Identify Crystal Stemware

Look closely at the stem of the crystal or on the bottom of the base for a mark or signature from the manufacturer. If there is a mark or a symbol but not a full name, you may need to identify the mark first. For instance, Lenox may be identified by an "L" in a wreath, while Oneida has an intertwined "OC" and Royal Doulton has a crown symbol.

Look up the manufacturer in your reference book or on websites such as Replacements.com or MatchYourCrystal.com. You can then look up the pattern that matches the crystal stemware to identify the piece. (See Resources)
