💡Expert Tips

Tip 1

Genuine Tiffany Studios lamps (1895-1933) are extremely rare and valuable. The vast majority of "Tiffany-style" lamps on the market are reproductions — this does not make them worthless, but a genuine Tiffany lamp vs. a reproduction is the difference between hundreds and hundreds of thousands of dollars

Tip 2

Examine the shade glass from inside with a flashlight: genuine Tiffany glass is thick, rippled, and shows color variation within each piece. Reproduction glass tends to be thinner, flatter, and more uniform

Tip 3

Check the copper foil on the shade: genuine Tiffany pieces have irregular, hand-applied copper foil between glass pieces. Machine-made reproductions have uniform, perfectly straight foil lines
