A really nice quality Art Nouveau style vintage glass shade, could be used for ceiling or table lamp or standard lamp, its mottled glass with a flared rim, some tiny little flecks which I think are in the manufacture, some slight wear where they were hung on a ceiling but only marks from the hardware, I think these are from around 1980s - 90s, commensurate with age and mentioned for complete accuracy otherwise in very good condition. Measuring 31 cm in diameter x 16 cm high or deep, x 3 cm in diameter where the hardware would go approx 
This auction is just for 1 but I have 8 of them if anyone is interested in more than one, they came from a restaurant and were used on the ceiling but I think they could be used for any type of lamp 
they are heavy so if used for the ceiling they would probably require a ceiling rose
