It isn't just about diamonds, the famous blue box, or our favorite Audrey Hepburn flick. The Tiffany & Co. legacy goes beyond jewelry, and the iconic brand has had its hand in everything from cell phones to trophies. Here are 10 surprising things that Tiffany & Co. has made:

1. The Most Popular Engagement Ring Ever

Charles Lewis Tiffany was the first jeweler to elevate a diamond solitaire on prongs so light could show through the shimmering facets. Before that, diamonds were put into bezel settings. The Tiffany setting remains a worldwide bestseller.

2. The 925 Stamp for Sterling Silver

The 925 sterling silver stamp was started in 1851 by Charles Lewis Tiffany. The stamp was later adopted by the US government, and it has become a standard for all sterling silver.

3. The New York Yankees Logo

Louis B. Tiffany (son of founder Charles) originally designed the overlapping NY letters as part of a medal for an NYPD officer in 1877. The letter motif was later adopted by the Yankees. It seems befitting since Tiffany also makes the World Series Trophy.

4. One of the World's Largest Yellow Diamonds

Charles Lewis Tiffany purchased it in 1878 for $18,000. It weighed 287 carats originally, but it was reduced to 129 carats during the cutting process. It is on display at the company’s flagship store on 5^th Avenue.

5. The Vince Lombardi Super Bowl Trophy & Various Super Bowl Rings

This 7 pound sterling silver trophy has been made by Tiffany since 1967. As for the Super Bowl rings, the NFL has commissioned a variety of jewelers to make each year’s design. Tiffany & Co. most recently made rings for the New Orleans Saints after their 2010 win.

6. Lots of Other Trophies

Tiffany & Co. makes the PGA Fed Ex Trophy, which weighs an astounding 33 pounds. The company also makes the Triple Crown of Polo Championship Trophy and the Nascar Nextel Cup. Roger Federer, one of our all-time favorite tennis players, is seen above holding a US Open trophy made by Tiffany & Co.

7. Ceremonial Civil War Swords

These 19th century swords are intricately forged with various battle symbols. Tiffany & Co. was known as one of the better sword-makers of the era, and their blades were typically inscribed with the company's name and the year 1864.

8. An 18K Gold Bra

Created by famed designer Elsa Peretti, this mesh triangle top bra was made in the late 1970s, during the pinnacle of the disco age. It definitely suited Elsa’s club-going lifestyle.

9. The Great Seal of the United States

The Great Seal was redesigned by Charles Lewis Tiffany in the 1880s and it has become one of our country's best-known symbols. The original seal was designed by three of the founding fathers in 1776. Tiffany's revised seal graces the back of the $1 bill.

10. One of the World’s Most Expensive Cell Phones

The $94,000 flip phone was designed in 2008 for Japanese company SoftBank. The platinum phone was covered in 18.34 carats worth of diamonds. Only 10 were made, and they sold out within 3 days. The pricey phone has since been surpassed as the world’s most expensive. The new winner is the $8-million-dollar Diamond Rose iPhone.
