THE JOURNEY OF A DIAMOND

From darkest mines to lands far and near..!

Diamonds are formed deep inside the core of the earth and they traverse a spectacular journey to reach their true pinnacle – one of beauty and grace.

The Journey of a Diamond

Formation

A hundred kilometers below the earth’s surface, carbon-bearing materials are exposed to high pressure at a comparative temperature range of 900°C - 1,300°C. Under such hot temperatures, a crystalline lattice structure reaches its final unique form which humans know as diamonds. A series of powerful volcanic eruptions and geological upheavals force the diamonds up onto the surface of the earth.

Mining

Diamond mining is a long, exhausting and challenging task. For a part of diamond to be discovered, it is estimated that 15-30 million parts of waste should be eliminated. A gravity-based device, known as Concentrate is used to sort/filter the portions of the earth which are estimated to be the home of diamonds. Finally, x-ray technology is used to determine the difference between the diamond concentrate and effluent matter.

Sorting

After extraction, rough diamonds are delivered to sorting experts to be categorised, segmented and valued. At present, there are over 15,000 different categories based on size, shape, quality, and colour. Once cleansed and sorted as per carat weight, each stone is individually inspected and assessed.

Cutting

Diamond cutting refers to the process of changing a rough stone into a faceted stone. This process is considered a truly difficult and highly skilled practice.
The cutting process is made up of 4 steps -

  • Cleaving – Separating the rough diamond into separate pieces, to be finished as separate gems.
  • Bruting - Two diamonds are set onto spinning axles turning in opposite directions to grind against each other so as to achieve a round shape
  • Polishing - The facets are cut onto the diamond and final polishing is performed.
  • Final inspection – Completely cleaning the diamond in acids, and examining whether it meets the quality standards of the manufacturer.

Grading

It is often said that grading a diamond is always as difficult as mining the diamond itself. Diamond clarity is marked by determining the number, size, relief, nature, and position of the many characteristics that make up the diamond. Specialised labs evaluate the diamonds on the 4C’s – Colour, Clarity, Cut and Carat and certify them accordingly. Armed with a proper grading certificate, the diamonds are now ready to be adorned as jewels.

Selling

We now arrive at the final footprint for a diamond. Every diamond with its certification arrives at the doorsteps of the seller/distributor, manufacturer, wholesaler or retailer. Thus diamonds travel this momentous journey of more than a thousand miles—from the deep, fiery heart of the Earth, to mines resting just below the surface, to the homes of diamond-lovers across the globe.
