Tiffany & Co. is a jewelry company founded by Charles Lewis Tiffany and John B. Young in New York City in 1837. It is considered the world's finest jewelry company.

Tiffany & Co has stores in major cities all over the world.

The first store was located on Broadway and had a revolutionary policy where each item's price was non-negotiable. In 1853, Charles Lewis Tiffany assumed control of the entire company.

The company now sells high-end household items as well.

The Tiffany flagship store on New York's Fifth Avenue is a tourist attraction, largely as a result of the 1961 movie Breakfast at Tiffany's which starred Audrey Hepburn.

Tiffany & Co. offers a wide array of jewelry in many price ranges and guarantees its quality. According to their own website they designed the Great Seal of the United States in 1885.
