Siegelson is the most important dealer of 20th-century jewelry in the world. A third generation American gallery, Siegelson has amassed the greatest collection of iconic jewels for sale. Vogue Paris proclaimed “Lee Siegelson, New York's King of Jewelry.” The Financial Times said that “Lee Siegelson is at the vanguard . . . bringing antique and period jewelry out from its exquisitely carved ivory tower, and presenting it in a contemporary context . . . making it more relevant to fashion, style and today's international design and art‑collecting community.” President of Christie’s Asia Francois Curiel said, “Siegelson demonstrates that at this level, the traditional barriers between jewelry and art disappear, and jewels which are one-of-a-kind become true works of art.” Martin Chapman, Curator in Charge of European Decorative Arts and Sculpture, Legion of Honor, San Francisco said, “Lee Siegelson has the most impressive array of historical jewelry, with pieces that not only show great design, but also are associated with great names. For me, going through his booth is always a thrill—like going through Aladdin’s cave.”
