Wiener Werkstatte artisans studded this silver square brooch, based on a 1905 sketch by the architect Josef Hoffmann, with lapis, carnelians and coral. With its columnar bands, the piece echoes Hoffmann’s signature striped façades and slatted furniture. “And it powerfully evokes the whole Wiener Werkstätte circle: the female patrons who posed for Gustav Klimt wore just this kind of jewelry,” Garner says. $107,550 (est. $90,000–120,000) Christie’s New York, June 15, 2004.
