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.

Humanity has utilized salt for thousands of years, dating back to ancient civilizations. The U.S. alone consumes more than 48 million tonnes of salt per year.

In this graphic, we break down global salt production in 2023, measured in tonnes. These estimates come from the U.S. Geological Survey’s latest commodity report on salt.

Ample Supply

Salt is essential for human life, serving various purposes including food preservation, flavor enhancement, industrial processes, and health maintenance. The good news is that the world’s continental resources of salt are vast, and the salt content in the oceans is nearly unlimited.

China is currently the top producer of salt, with almost 20% of the output, followed by the U.S. (15%) and India (11%).
