8 Pc. Tiffany & Co. "Shell & Thread" (Circa, 1905) Sterling Silver Forks. Measures - 7" long. Weight - 16.09 troy oz. Shell & Thread was first introduced by Tiffany & Co. in 1905. Its design is typical of patterns made in England during the long reign of King George III. The raised-border edges, which accentuate the Classic Â“fiddleÂ” shape of the pattern, along with the superbly balanced shell motif give Shell & Thread the great advantage of being at home practically anywhere. This versatility and the beauty of Shell & Thread make it Tiffany's most popular Classic pattern.
