How are diamonds made?

Diamonds are one of nature's most celebrated creations, adored for millennia by lovers everywhere and often seen as symbols of commitment or wealth - diamonds have long been treasured relics! But have you ever asked yourself: How are diamonds made? Their formation involves amazing natural forces as well as cutting-edge technological processes! We will explain this journey here on Pompeii3 - from their birth deep within Earth to becoming sparkling gems that grace wedding ring sets or other jewellery items!

How Diamonds are Formed at Great Depths of the Earth

A process that takes place in the mantle of the Earth at a depth of between 240 and 390 kilometres, or 150 to 75 miles below the surface of the Earth, is used to produce diamonds. The temperature of the carbon atoms in these depths will reach up to 1000 degrees Celsius (1832 Fahrenheit) and a pressure of more than 725000 psi (5 GPa). The molecules of carbon under such pressure combine to form crystals, and this results in the hardness that is characteristic of each diamond.

Over millions of years, diamonds slowly move toward the Earth's surface via volcanic eruptions and are transported in rocks known as kimberlites and lamproites; once nearer its surface, these rocks erode, allowing the diamonds to be mined for mining purposes.

Process for Mining Diamonds

Diamonds come to earth via different processes and mining methods in different deposits and different types of diamonds (primary kimberlite or secondary alluvial).

• Primary Deposits: The primary deposits are subject to both an open-pit and underground mine, whereby kimberlite pipes are mined, crushed and refined to recover the diamonds.
• Secondary Diamond Deposits: This would involve the mining of diamonds that have been flown away by some natural forces such as rivers and streams; these types of diamonds are usually found in the river banks, beaches or offshore and retrieved by panning or dredging.

In the UAE, all our diamonds are responsibly mined at Pompeii3, in line with industry-grade standards.

Cutting and Polishing Process

Just like all glass cuts, these also go through the cutting and polishing process.

Even after mining, diamonds are not immediately produced as beautiful jewels that adorn gold engagement rings and cross necklaces; they need to undergo cutting and polishing to reveal their full glory and glow.

• Cleaving or Sawing: This is a rough diamond that is sliced along its natural lines of the grain into smaller and easier to handle sizes using cutting tools or saws.
• Bruting: Diamonds that undergo this technique have their shape altered into round forms, the most preferred shape used in jewellery such as wedding ring sets.
• Faceting: The process is the one where the diamond is cut to provide a few faces or flat surfaces which reflect the light in the most opportune manner.
• Polishing: The diamond is sliced to bring out clear sparkling cuts to the diamond and make it appear as smooth as possible.

Diamond as a Sign of Commitment

The use of diamonds as a symbol of rings has always been associated with engagement as it has long been held as a sign of love, commitment, and promise of future togetherness. At Pompeii3, we offer a spectacular collection of gold engagement rings with exquisitely cut diamonds appropriate for marking the milestone occasions in life.

Diamonds have always been used as engagement rings, but now they have shown their glitz and classiness in other types of jewellery like gold chains and even cross necklaces, where smaller diamonds can also be incorporated to provide extra shine and dazzle.

Final Thoughts

How are diamonds made? From its formation deep beneath the Earth to being set into jewellery pieces like wedding ring sets or gold chains to commemorating special moments in your life, each diamond's journey is remarkable. At Pompeii3, we take great pleasure in offering stunning diamond jewellery, including wedding ring sets, gold chains, cross necklaces, and engagement rings that showcase their natural beauty and charm - ideal pieces to commemorate some of life's most unforgettable milestones!
