Founded by Charles Lewis Tiffany and John Burnett Young in New York City in 1837, Tiffany & Co. is an American jewellery and silverware company whose legacy is filled with prestige and fine craftsmanship.

In 1902, Louis Comfort Tiffany, son of Charles Lewis Tiffany, became the company’s first official design director. He was a prominent figure in the Art Nouveau movement, and his naturalistic aesthetic and use of colour still remains an inspiration for Tiffany designers today. Inspired by the disorder of nature, Louis Comfort Tiffany became known for his organic designs. He incorporated flowers, fruit and insect motifs into his designs, and used gemstones such as garnets to portray berries and green enamel for leaves.

The company’s aesthetic blossomed through the Art Deco era, and later became a huge success at the 1939 World’s Fair with their cocktail styles. This followed with the opening of the Tiffany flagship store, on the corner of 57th Street and Fifth Avenue, establishing the area as New York’s premier shopping destination.

This ring is in excellent condition.
