When it comes to antique lamps, the Dale Tiffany brand is one of the most well-known and sought-after. Dale Tiffany lamps are characterized by their intricate designs and elaborate craftsmanship. However, because of their popularity, counterfeit and fake Dale Tiffany lamps have flooded the market, making it difficult to determine their authenticity and value. In this article, we will guide you through the process of identifying genuine Dale Tiffany lamps through markings and other indicators.

History of Dale Tiffany Lamps

The Dale Tiffany Lamp Company was founded in 1979 by Louis Comfort Tiffany’s great-great-grandson, Charles Lewis Tiffany. Inspired by his ancestor’s love of stained glass, Charles began making Tiffany-style lamps with intricate designs and hand-cut glass pieces. Over the years, the company has expanded and now produces a wide range of lighting fixtures and home decor products.

What Are Dale Tiffany Lamp Markings?

Dale Tiffany lamps are marked in several ways to indicate their authenticity, including:

  • Signature
  • Label
  • Etching
  • Certificate of Authenticity


Many of Dale Tiffany’s lamps are signed by the artist who created them. The signature is usually located on the metal base of the lamp and may be accompanied by a date. If a lamp is signed, it’s a good indication that it’s a genuine Dale Tiffany lamp.


Dale Tiffany lamps also feature a label on the bottom of the base. The label will usually have the Dale Tiffany logo and the lamp’s model number. Some labels will also have the artist’s name and the year the lamp was made.


Some Dale Tiffany lamps feature an etched mark on the glass. This mark usually consists of the Dale Tiffany logo and the artist’s name. The etching can be difficult to see, so it’s important to inspect the lamp closely under good lighting.

Certificate of Authenticity

For some of their higher-end lamps, Dale Tiffany provides a certificate of authenticity. The certificate will have the lamp’s model number, the artist’s name, and a statement of authenticity.

How to Identify Counterfeit Dale Tiffany Lamps

Counterfeit Dale Tiffany lamps are unfortunately common and can be difficult to identify. Here are some things to look out for:

  • Missing markings or labels. If a lamp doesn’t have any markings, it’s likely not a genuine Dale Tiffany.
  • Poor craftsmanship. Dale Tiffany lamps are known for their intricate designs and high-quality materials. If a lamp looks cheaply made or has uneven cuts, it’s probably not genuine.
  • Price. Genuine Dale Tiffany lamps can be expensive, so if a lamp is being sold for significantly less than its market value, it’s worth being cautious.
