Hi Daniel,

Thank you for contacting Mearto with your appraisal inquiry.
Tiffany Studios lamps, crafted by Louis Comfort Tiffany in the late 19th and early 20th centuries, are renowned for their exquisite artistry and innovative use of stained glass. Featuring intricate designs inspired by nature, such as floral motifs and dragonflies, these lamps exemplify the Art Nouveau style. Each piece is unique, meticulously handcrafted, and often highly valued by collectors. Tiffany Studios' distinctive approach transformed ordinary lighting into luminous works of art.
The company was so influential that many companies copied their designs and there are a lot of early "knockoffs" on the market that may be nearly as beautiful but not nearly as valuable as an original Tiffany shade, which are marked, usually on both the outer rim and also the brass collar at the top of the shade.
I am very familiar with both Tiffany originals and reproductions and suspect this is a reproduction rather than an original.
Based on the photos and information provided, and subject to examination, this is:

An antique/vintage Tiffany style leaded glass and bronze chandelier shade
Lilypad pattern, early/mid 20th Century
Of circular section and conical form, with pierced ceiling mount. Presumed to be unmarked.
12 inches high; 24 inches diameter
CONDITION: This shade appears to be in good condition.
PROVENANCE: Acquired from an early 1900s home remodel
$ 150-200*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, or questions/concerns, and thank you again for using Mearto.
