Hello Frederick, I’m very glad that you chose Mearto for your online appraisal, Considering the photographs, overall pattern, glass quality and the colours, I concluded that this is an Entirely Hand Made Stained Glass Tiffany Style Lamp. The piece dates back to the period from 1980 to 2000. The piece is made by the company Meyda Tiffany, which is a contemporary American lighting company with a design reproducing in the original Tiffany style. The glass shade depicts hanging rose from above. The colours are vibrant and the quality is good for a contemporary piece. The company is still in production and new items are valued higher since this does not hold antique value. The piece has a metal body and base, not very detailed in term of decoration. The piece has a Meyda Tiffany label on it. The piece is in good condition without visible problems. Entirely hand made. Dimensions: Unknown. Condition: The piece is in good condition without visible problems. Provenance: Belongs to the current owner's mother. 200-300$.
