Query: What is the biggest diamond?
The Cullinan Diamond is the largest gem-quality rough diamond ever found, weighing , 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.
Type I diamond has nitrogen (N) atoms as the main impurity, at a concentration of up to 1%. If the N atoms are in pairs or larger aggregates, they do not affect the diamond's color; these are Type Ia. About 98% of gem diamonds are type Ia: these diamonds belong to the "Cape series", named after the diamond-rich region formerly known as Cape Province in South Africa, whose deposits are largely Type Ia. If the nitrogen atoms are dispersed throughout the crystal in isolated sites (not paired or grouped), they give the stone an intense yellow or occasionally brown tint (type Ib); the rare canary diamonds belong to this type, which represents only ~0.1% of known natural diamonds. Synthetic diamond containing nitrogen is usually of type Ib. Type Ia and Ib diamonds absorb in both the infrared and ultraviolet region of the electromagnetic spectrum, from 320 nm. They also have a characteristic fluorescence and visible absorption spectrum (see Optical properties).
Diamond is a good electrical insulator, having a resistivity of 100 GΩ·m to 1 EΩ·m (10 to 10 Ω·m). Most natural blue diamonds are an exception and are semiconductors due to substitutional boron impurities replacing carbon atoms. Natural blue or blue-gray diamonds, common for the Argyle diamond mine in Australia, are rich in hydrogen; these diamonds are not semiconductors and it is unclear whether hydrogen is actually responsible for their blue-gray color. Natural blue diamonds containing boron and synthetic diamonds doped with boron are p-type semiconductors. N-type diamond films are reproducibly synthesized by phosphorus doping during chemical vapor deposition. Diode p-n junctions and UV light emitting diodes (LEDs, at 235 nm) have been produced by sequential deposition of p-type (boron-doped) and n-type (phosphorus-doped) layers.
There is a supplemental letter from the Gemological Institute of America stating that the diamond has been determined to be a Type IIa diamond. Type IIa diamonds are the most chemically pure type of diamond, and often have exceptional optical transparency. Type IIa diamonds were first identified as originating from India, particularly from the Golconda region, but have since been recovered in all major diamond-producing regions of the world. Famous examples of Type IIa diamonds are the 530.20 carat Cullinan I and the 105.60 carat Koh-i-noor.
The supplemental letter from the GIA is accompanied by a monograph from the Gemological Institute of America which features additional photographs, data collection charts and gemological research which details the rarity of the Elizabeth Taylor Diamond.
. The $100 trillion (10) banknote (Pick No. 91) is the largest denomination ever issued by the Reserve Bank of Zimbabwe and is accepted by most numismatists as a banknote with the most zeroes ever shown in the design. Before 16 January 2009 the 500 billion dinar (5×10) banknote of Yugoslavia (Pick No. 137) held such status.
Sam Carter (Nigel Patrick) is a jeweller's clerk who dreams of stealing a fortune in diamonds and eventually does so but kills a man in the process. He then embarks on the highlife but is pursued across Europe by Milo March (Jack Palance) a private detective who suspects that not all is above board. However, Milo is not alone in his pursuit as Trudi Hall (Anita Ekberg) has her own ideas as to how the money would be best spent. Also two thugs, Martin Lomer (Bonar Colleano) and Gerard Heinz (Robert Stone) are after the Largest Diamond in the stolen hoard. All of the main characters end up fighting and trying to outwit each other over the Largest Diamond worth $700,00 on a Train going to London. This Precious Diamond is described by Milo March (Jack Palance) as: "$700,000 of unhappiness" because people are willing to do anything, even kill, to get it.Alan Ladd was originally announced to play the lead. Then Victor Mature was going to play it.
The game takes place in no specific setting, combining some elements of fantasy such as elves and other magical creatures with more modern elements such as a prominent robot NPC. The story is that many years ago, an ancestor of the player embarked on a courageous journey to a faraway kingdom where they discovered what is considered to be the largest diamond in the world, the "Fantasia Diamond". This priceless heirloom was passed down from generation to generation, despite all manner of thieves that attempted to steal it for themselves. Although it was safe for generations, thieves were finally successful in taking the diamond from the player's home and whisking it away to a large castle on the other side of a river. To retrieve it, the master spy Boris was dispatched, but he was captured and is being held prisoner. Now, the only way to recover the diamond is for the player go into the castle themselves, attempt to retrieve the diamond, free Boris the master spy from his prison, and safely return home.
Diamond type is a method of scientifically classifying diamonds by the level and type of their chemical impurities. Diamonds are separated into four types: Type Ia, Type Ib, Type IIa, and Type IIb. The impurities measured are at the atomic level within the crystal lattice of carbon atoms and so, unlike inclusions, require an infrared spectrometer to detect.
Type II diamonds have very few if any nitrogen impurities. Pure (type IIa) diamond can be colored pink, red, or brown owing to structural anomalies arising through "plastic deformation" during crystal growth; these diamonds are rare (1.8% of gem diamonds), but constitute a large percentage of Australian diamonds. Type IIb diamonds, which account for ~0.1% of gem diamonds, are usually a steely blue or gray due to boron atoms scattered within the crystal matrix. These diamonds are also semiconductors, unlike other diamond types (see Electrical properties). Most blue-gray diamonds coming from the Argyle mine of Australia are not of type IIb, but of Ia type. Those diamonds contain large concentrations of defects and impurities (especially hydrogen and nitrogen) and the origin of their color is yet uncertain. Type II diamonds weakly absorb in a different region of the infrared (the absorption is due to the diamond lattice rather than impurities), and transmit in the ultraviolet below 225 nm, unlike type I diamonds. They also have differing fluorescence characteristics, but no discernible visible absorption spectrum.
The dwarf planet Ceres is by far the largest asteroid, with a diameter of . The next largest are 4 Vesta and 2 Pallas, both with diameters of just over . Vesta is the only main-belt asteroid that can, on occasion, be visible to the naked eye. On some rare occasions, a near-Earth asteroid may briefly become visible without technical aid; see 99942 Apophis.
Cassius is a male saltwater crocodile ("Crocodylus porosus") recognized by the Guinness World Records as the world's largest crocodile in captivity in 2011. The animal measures in length, weighs approximately and is estimated to be more than 110 years old. Kept at the Marineland Crocodile Park, a zoo on Green Island, Queensland, Australia, Cassius was officially recognized by Guinness in 2011, but lost the title in 2012 to Lolong, a saltwater crocodile caught in the southern Philippines. Cassius again holds the record since Lolong's death in 2013.

The "World's Largest Dinosaur" is the name of a model "Tyrannosaurus rex" located in the town of Drumheller in the Canadian province of Alberta. Built of fiberglass and steel, has a height of and a length of , considerably larger than the largest known specimens of the actual dinosaur which reached up to in length, and was up to tall at the hips. The dinosaur was built while former mayor Phil Bryant was in his term.
In the United Kingdom, the medal, more properly known as "The Queen's Diamond Jubilee Medal", was designed by Timothy Noad, a calligrapher and illuminator. It depicts on the obverse the Ian Rank-Broadley effigy of the Queen crowned with a tiara and is circumscribed by the inscription "ELIZABETH II DEI GRATIA REGINA FID DEF" (Latin for "Elizabeth II by the Grace of God, Queen, Defender of the Faith"). The reverse shows a faceted hexagon with a crowned royal cipher, inscribed with the years 1952 and 2012.
Eight Commonwealth realms in the Caribbean—Antigua and Barbuda, The Bahamas, Barbados, Grenada, Jamaica, Saint Kitts and Nevis, Saint Lucia, and Saint Vincent and the Grenadines—have each issued a Diamond Jubilee medal. The obverse bears the same effigy of the Queen as does the British medal circumscribed by the words "DIAMOND JUBILEE HM QUEEN ELIZABETH II". The reverse shows the royal cypher of Elizabeth II with "CARIBBEAN REALMS" above and the years "1952–2012" below. The medal itself is rhodium plated.
There were larger dinosaurs, but knowledge of them is based entirely on a small number of fragmentary fossils. Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur "Argentinosaurus huinculensis", which is the largest dinosaur known from uncontroversial evidence, estimated to have been and long. Some of the longest sauropods were those with exceptionally long, whip-like tails, such as the "Diplodocus hallorum" (formerly "Seismosaurus") and the 33- to 35-metre-long (108–115 ft) "Supersaurus". The tallest was the "Brachiosaurus".
However, the Guinness World Records recognises the Hungarian 1 billion b.-pengő (10) banknote (Pick No. 137) as the world's largest denomination, although the 100 million b.-pengő (10) (Pick No. 136) was the largest denomination to be issued.
In 2006, the Guinness Book of World Records certified Katlinel and Les Hartness of California as having the largest hand-carved wooden rocking horse on record. This rocking horse was built in 2000 and is 7 feet 8 inches tall and weighs 1,200 pounds. It can be seen at renaissance faires, faerie festivals, and at private parties and events where up to 3 adults or 4-5 children can ride it together at one time. According to Les and Katlinel, the youngest rider has been six weeks old and the oldest, 94 years.
Many of the conflicting versions about the origin of the "Spoonmaker's Diamond", a major treasure of the Topkapi Palace in Istanbul, link it with Ali Pasha – though their historical authenticity is doubtful.
The heaviest known cephalopod, and the largest living invertebrate, is the colossal squid. The largest recorded specimen of this species, caught in the Ross Sea in 2007, weighed . However, its beak is not the largest known from this species; even bigger colossal squid beaks have been recovered from the stomachs of sperm whales, indicating that this species can grow larger still.
The dollar coin is a United States coin worth one United States dollar. It is the second largest U.S. coin currently minted for circulation in terms of physical size, with a diameter of 1.043 inches (26.5 mm) and a thickness of .079 inches (2 mm), coming second to the half dollar. Dollar coins have been minted in the United States in gold, silver, and base metal versions. Dollar coins were first minted in the United States in 1794. The term silver dollar is often used for any large white metal coin issued by the United States with a face value of one dollar, whether or not it contains some of that metal. While true gold dollars are no longer minted, the Sacagawea and Presidential dollars are sometimes referred to as golden dollars due to their color.
While it is difficult to tell exactly what status the Pumpkin Diamond currently enjoys, the official GIA web site reports it as "one of the largest Fancy Vivid orange natural color diamonds in the world." The Color Diamond Encyclopedia, on the other hand, terms it "the world's largest fancy vivid orange diamond." In 1997, when it was purchased by The House of Harry Winston, the Gemstone Forecaster referred to it as "the only vivid orange ever graded by the GIA" (which is incorrect as there are several other vivid orange stones graded by GIA and offered for sale on websites, past and present).
Today, annual global rough diamond production is estimated to be about , of which 92% is cut and polished in India, mostly in the city of Surat. Some 85% of the world's rough diamonds, 50% of cut diamonds, and 40% of industrial diamonds are traded in Antwerp, Belgium—the diamond center of the world. The city of Antwerp also hosts the Antwerpsche Diamantkring, created in 1929 to become the first and biggest diamond bourse dedicated to rough diamonds. Antwerp's association with diamonds began in the late 15th century when a new technique to polish and shape the gems evolved in this city. The diamond cutters of Antwerp are world renowned for their skill. More than 12,000 expert cutters and polishers are at work in the Diamond District, at 380 workshops, serving 1,500 firms and 3,500 brokers and merchants.
The theme of the museum is the alluvial diamant diggings of this region 1925–1935, then the richest public diggings in the world. The biggest pure red diamond (flawless) ("pigeon blood red") in the world was found here in 1927. The stone was of . It was sold for 66 pounds and was later valued at $150,000. The stone would be worth more than $6 million today and is the purest red diamond in the world.
The biggest diamond rush in history took place in March 1927 on the farm Grasfontein near Lichtenburg, when 25,000 runners took part to peg their claims.
The town accommodates a Social-historical museum and an Agricultural museum with a big collection of antique tractors and many other interesting objects, and the new Digging Museum.
In 2017 the company set a new record at Christie's Magnificent Jewels sale in Geneva when it sold the world's biggest-ever emerald cut diamond offered at auction. The 163.41-carat D Flawless stone, which was cut from a 404 carat rough, was incorporated into a necklace designed by Fawaz Gruosi. It fetched 33.5 million Swiss francs, beating the previous record for a D Flawless diamond by nearly five million Swiss francs.
