It has long been a symbol of eternal love, given as an engagement or wedding ring or as an anniversary present.  Learn all about the diamond’s history, meaning, and symbolism!

Diamond’s Color

While sparkling and clear diamonds are the most recognizable, the gem comes in a range of colors, including brown, yellow, red, pink, blue, and green. Blue, green, and red are the rarest. The color of a diamond is dependent on the impurities in the gem.

Diamonds can be transparent, translucent, or opaque, but most diamonds used as gemstones are transparent and colorless.

History of Diamond

  • The oldest diamonds were formed more than 3 billion years ago.
  • It’s believed that the infatuation for diamonds originated in India, where they were collected from rivers and streams. According to historians, India began trading in diamonds as far back as the 4th century B.C. The gem was originally reserved for India’s most wealthy. Soon, though, India’s diamonds made their way to Western Europe and, by the 1400s, became fashionable among Europe’s high society.
  • In 300 B.C., diamonds were used to engrave other gems in India.
  • The first diamond engagement ring was given to Mary of Burgundy by Archduke Maximillian of Austria in 1477.
  • The origin of the blue Hope diamond has been traced back to India’s Golconda mining area in the 1600s. It was then sold to King Louis XIV of France. It currently can be found at the Smithsonian Institution in Washington, D.C.
  • The largest diamond ever found was unearthed from South Africa’s Premier mine in 1905. Weighing in at 3,106 carats, the gem produced the Cullinan I diamond, also known as the Great Star of Africa. The 530-carat drop-shaped diamond is set in the Sovereign’s Sceptre with a Cross and housed with the other Crown Jewels in the Tower of London. Cullinan II (the Lesser Star of Africa) cut from the same diamond is also part of Great Britain’s crown jewels.

Where are Diamonds Found?

Diamonds form under extreme temperature and pressure conditions found more than 75 miles under the Earth’s surface. 

A gem-quality diamond is more than 99.9 percent carbon, making it one of the purest of all gems. It’s the only gem made up of a single element, while trace elements make up the remaining percentage. Its crystal structure is isometric, meaning that its carbon atoms are bonded together the same way in all directions, creating its incredible hardness.

Once formed, diamonds are pushed upward by volcanic activity until they reach the Earth’s surface or just below. Diamonds are found in a few different locations: rock, alluvial deposits, glacial tills, and kimberlite pipes.

But diamonds are hard to come by, evident by the fact that the average yield from a diamond mine is 1 part diamond to 1 million parts rock.

It’s believed that diamonds were first discovered in India before Brazil became an important factor in the gem’s supply chain in the 1700s. Other deposits were discovered in South Africa in the late 1800s. In addition to South Africa and other African nations, locations like Russia, Australia, and Canada play a role in today’s supply chain.

Diamonds in Jewelry

It has long been stated that a diamond is a girl’s best friend. For hundreds of years, diamonds have been used for engagement and wedding rings, but they are also fashionable for everyday wear. The gem is used for necklaces, broaches, rings, and bracelets.

It is believed that the first engagement ring that contained a diamond was given in 1477 by Archduke Maximilian of Austria to his fiancee, Mary of Burgundy. Today, diamonds are the most popular choice of stone for an engagement ring.

Diamonds can be found in a variety of cuts—round, oval, princess, and heart, to name a few. The diamond has a Mohs Hardness rating of 10, and is so hard that the only thing that can scratch it is another diamond.
