Tiffany & Co., often simply called Tiffany, is an American luxury jewelry and specialty retailer known for its platinum and diamond jewelry、The company was founded in 1837 by Charles Lewis Tiffany as a stationery store on Fifth Avenue in New York City.

The iconic Tiffany Blue box, which has become synonymous with the brand, dates back to the early 20th century when it was introduced as a way to protect and present the jewelry、The color blue was chosen because it was believed to be calming and soothing, making it ideal for a highend retail environment.

Tiffany's most famous product is undoubtedly the Tiffany engagement ring, featuring a single round brilliantcut diamond set in a sixprong setting atop a platinum band、This design, created by Charles Lane in 1961, became the standard for engagement rings worldwide due to its simplicity and elegance.
