The stories and histories of the most famous diamonds
You may have heard of the Cullinan Diamond or the Hope Diamond before, but do you know the stories behind these legendary finds?
Today’s infographic looks at the history and characteristics of six of the most famous diamonds.
A Diamond Primer
Every diamond is unique, and as a result the value of a particular diamond is partially determined by the eye of the beholder. The diamond industry generally uses a set of criteria called the Four C’s to help evaluate the potential value of a diamond: Clarity, Cut, Carats, and Color.
Most diamonds found have major deficiencies in one or more of the above categories. For example, while a diamond may be clear and large in size, it may have a less desirable color and shape. In a previous infographic, we explain the importance of these characteristics in more depth, and we’ve also previously posted on the significance of rare-colored diamonds.
The most famous diamonds in the world are exceptionally rare: they tend to excel in all four of the above categories. They are a desired color and shape, have great clarity, and are giant in size.
The Most Famous Diamonds
The stories behind six of the most famous diamonds in brief:
The Cullinan Diamond: Perhaps the most well-known, the Cullinan Diamond was discovered in 1905 in South Africa. Weighing in at 3,106.75 carats, the Cullinan is the largest rough gem-quality diamond ever discovered. The diamond was ultimately cut into nine smaller stones including the 530.20 carat Star of Africa, which is valued at over $400 million alone.
The Hope Diamond: The Hope Diamond is a grayish-blue diamond that was discovered in India at an unknown date. It has a long history, in which it changed hands numerous times between countries and eventually ended up at the Smithsonian Institute in Washington, D.C.
The Centenary Diamond: The Centenary Diamond is considered to be one of the most flawless diamonds, both internally and externally. Discovered in South Africa, it was unveiled in its final form by De Beers in 1991. The current owner is unknown.
The Regent Diamond: This pale blue diamond was discovered by a slave in India in 1698. After eventually making it to the crowns of Louis XV and Louis XVI in France, it is now on display at the Louvre in Paris and weighs 140.64 carats.
The Koh-i-Noor Diamond: Meaning “Mountain of Light” in the Persian language, this diamond was discovered at a mine in India. It is of the finest white color, and made its way from a Hindu temple eventually to the Crown of Queen Elizabeth in 1850.
The Orlov Diamond: Discovered in India at an unknown date, this jewel retains its traditional Indian rose-style cut. The Orlov, which weighs in at 189.62 carats and is white with a faint bluish-green color, now rests in the Kremlin in Russia.
The world’s most famous diamonds all have intriguing stories behind their discoveries. However, a diamond prospector doesn’t need to find a diamond to strike it rich: check out the infographic story of Diamond Fields, a diamond company that ended up finding and auctioning off one of the world’s richest nickel deposits for billions.

While India and China dominate the demand for gold, both countries face different scenarios when comparing supply gaps.
With its huge jewelry industry, India’s consumption is 50 times higher than its domestic supply. Meanwhile, China produces more than one-third of the gold it demands.
This graphic compares gold demand (in tonnes) versus domestic gold production in 10 selected countries. The data comes from the World Gold Council and was compiled by The Gold Bullion Company as of 2023.
India’s Massive Gold Market
Gold holds a central role in India’s culture, considered a store of value, a symbol of wealth and status, and a fundamental part of many rituals. The metal is especially auspicious in Hindu and Jain cultures.
With a population of over a billion, India tops our ranking with substantial gold demand, primarily for jewelry and gold bars.
Country | Gold Production in Tonnes (2023) | Gold Consumer Demand | Deficit or Surplus |
---|---|---|---|
🇮🇳 India | 15 | 748 | -733 |
🇨🇳 China | 378 | 910 | -532 |
🇹🇷 Turkey | 37 | 202 | -165 |
🇺🇸 United States | 167 | 249 | -82 |
🇧🇷 Brazil | 86 | 17 | 69 |
🇮🇩 Indonesia | 133 | 45 | 88 |
🇲🇽 Mexico | 127 | 15 | 112 |
🇨🇦 Canada | 192 | 24 | 168 |
🇷🇺 Russia | 322 | 71 | 251 |
🇦🇺 Australia | 294 | 24 | 270 |
China ranks second, with demand driven primarily by gold’s role as a store of value, especially by the People’s Bank of China. Central banks seek gold as a hedge against inflation and currency devaluation. Since 2022, the People’s Bank of China has increased its gold reserves by 316 tonnes.
In third place for gold demand, the U.S. consumed 249 tonnes in 2023, against a domestic supply of 167 tonnes.
Turkey ranks fourth, with mine production in 2023 at 37 tonnes, which is five times lower than its demand of 202 tonnes.

Visualized: China’s Steel Demand Through Time
China’s steel demand remains robust, but the breakdown on a sectoral level has shifted since 2010. Which sectors are driving steel consumption?
Visualized: China’s Steel Demand Through Time
As the world’s manufacturing powerhouse, China has the highest global demand for crude steel, with the market experiencing remarkable growth since 2010.
In 2023, China’s crude steel demand reached 911 million metric tons. This is up an estimated 50% from 609 million metric tons 13 years earlier. When adding in exports and changes to inventory, China surpassed 1 billion metric tons of steel production for the fifth year in a row.
However, the growth in demand for the metal has not been even across industries. In this graphic, we’ve partnered with BHP to visualize how demand for steel on a sectoral level has shifted between 2010 and 2023.
The Sectors Driving Steel Demand
We observed demand for crude steel across the following sectors:
- Machinery: machinery used in power, construction, metals and mining, agriculture, tools and parts, etc.
- Infrastructure: roads, railways, subways, pipelines, etc.
- Construction: urban and rural housing, office buildings, industrial buildings, WRAC buildings (wholesale, retail, accommodation, catering), etc.
- Transport: light-duty vehicles, trucks and buses, auto parts, shipbuilding, etc.
- Consumer Durable Goods: refrigerators, washing machines, air conditioners, microwaves, etc.
- Metal Goods: containers and hardware, etc.
- Other: smaller categories, statistical change, etc.
In 2010, the largest share of Chinese demand came from the construction sector. Construction accounted for an estimated 42% of the country’s total steel needs. Machinery (20%) and infrastructure (13%) were the industries with the second- and third-highest demand, respectively.
Over the past 13 years, however, demand has shifted towards the machinery and infrastructure industries.
Sector | 2010 (%) | 2023 (%) |
---|---|---|
Machinery | 20 | 30 |
Infrastructure | 13 | 17 |
Construction | 42 | 24 |
Transport | 12 | 9 |
Durable Goods | 7 | 8 |
Other | 6 | 12 |
The demand for steel from the construction industry is estimated to have dropped from 42% of total demand to 24%, as construction firms purchased 37 million metric tons less steel in 2023 compared to 2010. This slump can, in part, be attributed to the Chinese real estate crisis and developer bankruptcies. Both of these factors led to a slowdown in residential building starts.
The machinery sector, on the other hand, has witnessed incredible growth. It rose from an estimated 20% share of overall Chinese steel demand in 2010 to 30% by 2023, boosted by an influx of equipment renewals. Infrastructure saw approximate growth of 13% to 17% over this timeframe.
Steel Demand for Transportation and Durable Goods
The share of steel used by the transport sector is estimated to have falled from 12% in 2010 to 9% in 2023. However, there was an uptick in the amount of steel used by the industry. It rose from around 73 million metric tons in 2010 to 82 million metric tons 13 years later. And, with more than half of all new electric vehicles (EVs) sold worldwide made in China, the sector could receive support if EVs continue to gain in popularity.
In fact, the green economy needs the steel industry—it remains vital for the production of emerging technologies. As such, it is important that nations take steps towards “cleaning” their steel industries. China is doing so with its focus on carbon capture, utilization, and storage technologies, employing green hydrogen metallurgy, and introducing electric furnaces.
Steel demand for durable goods rose slightly from 2010 to 2023. However, the relatively steady share masks the near-doubling of absolute steel purchased by this sector—up from 43 million metric tons to an estimated 73 million metric tons.
The Path Forward for Steel
The Chinese steel industry remains robust—growing by an estimated 50% from 2010 to 2023—despite significant shifts beneath the surface.
As the energy transition progresses, further changes in industry demand for steel are likely, especially with the increasing prominence of clean technologies, such as EVs. Conversely, demand from the construction industry remains closely tied to the outlook of the country’s housing sector.
