A Tiffany Studios Wisteria table lamp headlined a 20th century design sale at Sotheby's New York on June 11, achieving $575,000 against a $500,000 estimate - an increase of 15%.
The design is considered the apex of the firm's output and is crafted from 2,000 pieces of coloured glass, each of which has been individually cut.
A wealthy family from Tennessee originally bought it during the early 1900s.
The studio began producing lamps in 1895, with the Wisteria costing around $400 (equivalent to $10,500 today when adjusted for inflation).
Tiffany was famous for its production of glass and developed a range of effects that are still used today, from pearlescence to innovations in texture and opacity.
A four-piece coffee set by modernist designer Paul Lobel (1899-1983) sold for $377,000.
The lot was conceived in the early 1930s and exemplifies the optimism and utopian ideals of the age in its smooth lines and gleaming execution.
There are only four known specimens extant, two of which are in museum collections. The only other set on the market made $449,000 at Sotheby's in June last year.
