Tiffany & Co.
Jeweller and silver firm in New York. Adopted in 1851 the English sterling standard of 925/1000 as its standard in the United States.
Charles Lewis Tiffany and John B. Young opened a stationery and gift shop in New York. It became a jeweller and silver firm, and Edward C. Moore led the silver workshop.
Tiffany won a prize for its silver at the Paris Exposition of 1878, and the six-prong ring setting of 1886 became the standard for engagement rings. The blue colour and the boxes became symbols, and Tiffany has been part of LVMH since 2021.
TIFFANY & CO. and STERLING, often with pattern and order numbers that can be dated.
