A diamond is the hardest natural material known to man, ranking the highest on the Mohs scale of mineral hardness. However, for a diamond to reach its true brilliance, it must be cut and polished properly to unlock its inner fire – the undying sparkle that has attracted and enticed the hearts of countless millions.
The only "C" to be dependent on human knowledge, skill and efforts (the other C's being Colour, Clarity, and Carat), the ideal Cut is what transforms the rough diamond into the perfect, polished gem that we desire. An optimal cut that has the light reflecting out through the broad top of the diamond, allows the full majestic glory of its inner beauty to shine through in a dazzling radiance.
Diamonds are analysed from an economic point-of-view with two major objectives – ROI optimisation and Timeliness
Value maximisation is determined by several factors such as diamond value versus weight, also known as weight retention and general popularity of shapes amongst consumers.
Retention helps determine the best combination of finished stones as per carat value.
With coloured diamonds, cutting influences the value of a diamond and certain cuts can increase the colour quality of a diamond.
Minimising timelines to ensure rapid/quick saleability is another major consideration to be kept in mind.
Cleaving / Sawing
Cleaving helps separate a rough diamond into several separate pieces which are then converted into separate gems. Sawing refers to breaking rough diamonds into separate pieces with a saw or laser.
Bruting is a process by which two diamonds are set onto spinning axles turning in opposite directions, grinding upon each other until each takes a round shape.
Polishing helps to cut facets onto the diamond, after which the final polishing is carried out.
The final stage witnesses the cleaning of the diamonds in acid and checks are carried out to see if the required standards are adhered to on the finished stone.
