Victoria,

Thank you so much for confirming!

The company Dale Tiffany reproduces leaded lamps first developed by Louis Comfort Tiffany between 1890 and the 1920s but there is no family relationship and the name often confuses people. Dale Tiffany lamps are hand-make reproductions following the designs of LC Tiffany (and Tiffany Studios, Tiffany & Co.,) but there is a SIGNIFICANT difference in value, whether buying retail or at auction, the latter of which are the values Mearto provides.

Based on the photographs and information provided, and subject to examination, this is:

A pair of American Art Nouveau style bronze table lamp with “dragonfly” leaded and slag glass shade
Made and labeled by Dale Tiffany, numbered 5012/12000
23 inches tall; diameter of shade 16 inches; diameter of foot 10 inches
PROVENANCE: gift
$ 400-600 for the pair (would be $200-300 if a single lamp)
*represents a fair-market value for auction purposes; retail or asking price (such as seen on 1stDibs, Replacements, Chairish, Etsy, eBay or RubyLane) may vary. The following recent auction sales of similar Dale Tiffany lamps have been used to research the value of your lamps; you may find it useful to look at the estimates as well as the prices realized, which i have put in parenthesis:
