Journey of diamond from Mining to Retailing

As everyone knows that diamonds are among the most cherish items on the earth. Due to powerful volcanic activities 'pipes' are formed which are nothing but openings in the earth and forces the diamonds up through the pipes to the surface, along with other minerals such as kimberlite. Most of the diamonds which are forced up through the earth settled back into the kimberlite pipes are the primary deposits and diamonds that are formed their way into streams, rivers and seas; these are considered as secondary deposits.

Once diamonds and other minerals are discovered after the process of formation then mining operations are used, to extract these minerals. Mining methods differs based on the source of the diamonds. Primary deposits, in which diamonds are found near the surface or along kimberlite pipes require require open pit or underground mining operations. Secondary deposits are defined as diamonds that have traveled from their original location due to erosion. These require alluvial mining, which uncovers diamonds in seabed, coastal and marine/undersea locations.

Once the diamonds have been mined and processed, then the diamonds are delivered to sorting experts who classify and assign a value to them. The industrial quality diamonds which are small, lower quality stones are classified. In this sorting process, these diamonds are grouped, based on their size, shape, quality and color in to thousands of categories. Almost all rough diamonds have some differentiating marks, which make each one unique.

After sorting the next step for rough diamonds are cutting and polishing. Cutting of rough diamonds takes a great skill, with diligent techniques that have been practiced for generations. The activity takes place in South Africa, Belgium, China, India, Israel, Russia and the US, among other countries. A well-cut diamond shines light within itself, from one facet to another, as well as through the top of the diamond, and brings out its spectral brilliance.

After the diamond has being cut, polished and categorized, they are then sold via one of the 24 registered diamond exchanges (also called as 'bourses') situated all over the world or direct to wholesalers or diamond jewellery manufacturers. The polished diamonds are ready to be set into finished pieces of jewellery, designed by in-house teams - and sell it direct to retailers.

Today, diamonds are being procured as symbols of independence and success. Nowadays, diamond jewellery is the highest desired-after category of luxury goods, both by women for themselves and by men for gifts. The diamond industry engages million people over the world, both directly and indirectly, across a wide spectrum of roles from mining to retailing.
