The name Tiffany evokes quality, tradition and artistic innovation, mainly in jewelry, sterling silver, art glass and bronzes. Even a stamp indicating that something such as a porcelain dinner plate or a water glass is only just retailed by Tiffany, rather than made by Tiffany, serves as a mark of approval and good taste. Charles Lewis Tiffany started the dynasty selling jewelry in 1837, gradually retailing other items such as ceramics and glass. In 1851, Tiffany introduced to America the elevated sterling standard of silver used by the English for centuries, at a time when "coin" silver was the prevailing standard. His son, Louis Comfort Tiffany, revolutionized the art glass industry in the latter part of the 19th century and into the 20th century, with his beautiful Favrile glass vessels and bronze and glass lamps, candlesticks, candelabra, clocks, desk articles and stained glass windows. Later in the 20th century, hiring famous designers such as Paloma Picasso and Jean Schlumberger to design jewelry and tableware elevated many functional items to the status of art.
