From Mine To Market:
A Diamond's Journey


Taking over a billion years to form in the depths of the earth, a natural diamond goes through several trials and tribulations before it acquires its fabled lustre to adorn an exquisite piece of jewellery.

From diamond mines in southern Africa, Russia, Canada and Australia, to the cutter's plate in India, to jewellers in New York, London and Hong Kong, ultimately to be set in the ring of a beloved - it is a fascinating journey which explains why diamonds are some of the most beautiful gemstones known to mankind, and what makes them rare and precious.


FROM THE MINE



It takes more than a billion years for a diamond to form nearly 200 kilometres below the earth's surface under extreme conditions of temperature and pressure. Even in these conditions, the odds of a diamond forming are very low; often, the atomic structure of the resultant rock is far from perfect to qualify as a diamond.

It takes millennia for rocks bearing rough (uncut and unpolished) diamonds to be pushed up towards the earth's surface through volcanic activity, where they are ready to be mined.
Rough diamonds occur either in underground or open-pit mines, where they may be found anywhere from a few meters to a few hundred metres below the surface; or on the side of river beds, where they accumulate on the banks through continual erosion; or even at the bottom of the seabed.

Most of the world's rough diamonds are found in southern Africa, Russia, Australia and Canada. Rough diamond producers sell these to diamond manufacturers through periodic auctions, also known as 'sights'.

TO THE CUTTER'S PLATE



Diamonds go through a five-step cutting and polishing process:
1. PLANNING -
To determine parameters such as shape, facets and other dimensions to maximise the rough diamond's lustre.
2. CLEAVING -
To cut the rough diamond into smaller pieces as per the plan.
3. BRUITING -
To cut the diamond into a round shape using either a laser, a diamond disk, or two diamonds cutting against each other.


4. POLISHING -
To smoothen the facets of the diamonds to maximise its lustre.
5. INSPECTION -
To ensure that the diamond meets with the exacting standards set by the manufacturer.

Nine out of every ten rough diamonds mined globally are cut and polished by experienced manufacturers in India, mostly clustered around the western city of Surat (225 kms north of Mumbai).


TO THE JEWELLER'S DISPLAY



Cut and polished diamonds are set in jewellery by master jewellers according to exquisite designs created by some of the world's most accomplished jewellery designers.

Setting diamonds in jewellery is a fine art given to very few craftsmen who have accumulated experience through generations. The breath-taking beauty and lustre of a diamond is enhanced by the experienced hands of a master jeweller.
