The Tiffany Yellow Diamond is one of the largest yellow diamonds ever discovered. Its carat weight was originally 287.42 carats (57.484 g) in the rough when discovered in 1878 in the Kimberley mine in South Africa. It was cut into a cushion shape of 128.54 carats (25.108 g) with 82facets—24 more than a traditional round brilliant—to maximize its brilliance. The facet pattern features eight needle-like facets pointing outward from the culet (bottom) facet. Jewelry and diamond historian Herbert Tillander refers to this as a "stellar brilliant cut", and lists the gem in his book, Diamond Cuts in Historic Jewelry – 1381 to 1910 (1995), among other such diamonds: the Cullinan Diamond, the Koh-i-Noor, the Polar Star, the Wittelsbach, and others.
The gem has been displayed across the United States. Its permanent home is at the Tiffany & Co. flagship store in Midtown Manhattan, New York City.
Discovered in South Africa in 1877, the stone was purchased by New York jeweler Charles Tiffany. His gemologist, George Frederick Kunz, studied the gem for a year before beginning to cut it; reducing it from 287 carats (57.5g) to its current size. The cutting was carried out in Paris. It was later mounted by Jean Schlumberger.
In 1879, the Tiffany branch in Paris obtained the Tiffany Diamond, which weighed 287.42 carats in the rough. It was the largest yellow diamond found up to that time. The task of supervising the cutting of this stone was the responsibility of one George Frederick Kunz (1856–1932), a twenty-three-year-old gemologist who had just joined the firm. Kunz modified the accepted square antique brilliant cut, bringing the total facets to ninety. The result is a cut that returns a great deal of light to the eye. Large diamonds of comparable brilliance were not fashioned until well into the 20th century. 3–4:
The gem was on loan from Tiffany & Co. to the Smithsonian National Museum of Natural History in Washington, D.C., from April 18, 2007, until September 23, 2007. At the time, Jeffrey E. Post, the museum's gem curator, said that this was the largest diamond on display in the U.S. The famous Hope Diamond is only 45.5 carats, which is about one-third the mass of the Tiffany Yellow Diamond.
The diamond is known to have been worn by only four women during its lifetime. It was worn by Mrs. E. Sheldon Whitehouse at the 1957 Tiffany Ball held in Newport, Rhode Island, mounted for the occasion in a necklace of white diamonds.It was subsequently worn by Audrey Hepburn in 1961 publicity photographs for Breakfast at Tiffany's . In 2019, Lady Gaga wore the diamond at the 91st Academy Awards. Beyoncé wore the necklace in a collaboration campaign with Tiffany in 2021, becoming the first Black woman to wear the yellow diamond.
As of the 21st Century, the Tiffany Yellow Diamond has proven to be a source of controversy on the internet. It is widely assumed that the diamond was obtained through slave labor, thus making it a blood diamond. A notable incident would be when Beyoncé wore the diamond in 2021 and the subsequent backlash on social media.
Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium and/or sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor. Emerald is a cyclosilicate.
A gemstone is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks and occasionally organic materials that are not minerals are also used for jewelry and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity is another characteristic that lends value to a gemstone.
The Hope Diamond is one of the most famous jewels in the world, with ownership records dating back almost four centuries. Its much-admired rare blue color is due to trace amounts of boron atoms. Weighing 45.52 carats, its exceptional size has revealed new findings about the formation of diamonds.
Diamond cutting is the practice of shaping a diamond from a rough stone into a faceted gem. Cutting diamond requires specialized knowledge, tools, equipment, and techniques because of its extreme difficulty.
The Cullinan Diamond is the largest gem-quality rough diamond ever found, weighing 3,106.75 carats (621.35 g), discovered at the Premier No.2 mine in Cullinan, South Africa, on 26 January 1905. It was named after Thomas Cullinan, the mine's chairman. In April 1905, it was put on sale in London, but despite considerable interest, it was still unsold after two years. In 1907, the Transvaal Colony government bought the Cullinan and Prime Minister Louis Botha presented it to Edward VII, King of the United Kingdom, who had it cut by Joseph Asscher & Co. in Amsterdam.

A diamond cut is a style or design guide used when shaping a diamond for polishing such as the brilliant cut. Cut does not refer to shape, but the symmetry, proportioning and polish of a diamond. The cut of a diamond greatly affects a diamond's brilliance; this means if it is cut poorly, it will be less luminous.
A diamond simulant, diamond imitation or imitation diamond is an object or material with gemological characteristics similar to those of a diamond. Simulants are distinct from synthetic diamonds, which are actual diamonds having the same material properties as natural diamonds. Enhanced diamonds are also excluded from this definition. A diamond simulant may be artificial, natural, or in some cases a combination thereof. While their material properties depart markedly from those of diamond, simulants have certain desired characteristics—such as dispersion and hardness—which lend themselves to imitation. Trained gemologists with appropriate equipment are able to distinguish natural and synthetic diamonds from all diamond simulants, primarily by visual inspection.
Harry Winston was an American jeweler. He donated the Hope Diamond to the Smithsonian Institution in 1958 after owning it for a decade. He also traded the Portuguese Diamond to the Smithsonian in 1963 in exchange for 3,800 carats of small diamonds.
