Heritage Auctions will lead its early 20th-century design sale on 11 November 2026 with a Tiffany Studios Wisteria table lamp estimated at $500,000. The house says that figure is the highest estimate it has placed on a Tiffany lamp. The lamp's clustered glass shade, built up from hundreds of small pieces in a falling wisteria pattern, is one of the studio's most recognisable designs, and the estimate signals how strongly collectors now compete for the best examples.

The rest of the sale is built around the same period's decorative arts. Other table lamps include a red and green dragonfly design estimated at $100,000 to $150,000 and a maple-leaf design with a high estimate of $120,000. Beyond lighting, the sale offers Springtime, a leaded-glass window from 1920 showing a barefoot figure in a flowering landscape, estimated at $60,000 to $80,000, and an iridescent Favrile vase estimated at $7,000 to $9,000. A Lalique centrepiece, a Frank Lloyd Wright bookcase from a house in South Bend, Indiana, and lithographs by Alphonse Mucha and Henri de Toulouse-Lautrec each carry estimates up to $50,000.

The headline estimate also reflects a wider run of strong Tiffany results. Global sales of Tiffany Studios work passed $40 million in both 2023 and 2024. In late 2024 the Danner Memorial Window became the studio's most expensive work when it sold for $12.4 million at Sotheby's in New York, and a magnolia floor lamp followed with $4.4 million at the same house a year later. The standing record for a Tiffany table lamp remains $3.7 million, paid at Rago/Wright in 2021 for a Dandelion lamp first shown at the Paris 1900 World's Fair.

Heritage's decision to put the Wisteria lamp at the top of the sale, rather than burying it among other lighting, shows how central Tiffany has become to the design market. Whether the lamp reaches its estimate will be a useful test of that demand, but even as a pre-sale figure, $500,000 marks a new high-water mark for how Heritage values Tiffany lighting.
