Transformation from a Rough to a Beautiful Cut and Polished Diamond
Diamonds undergo a meticulous transformation from their rough state to the dazzling gems we see in exquisite jewellery pieces. The journey is a blend of art, science, and precision. Let’s take a closer look at this transformation.
Origins of a Diamond
Natural diamonds are formed deep within the Earth’s mantle under extreme pressure and high temperatures, taking almost three billion years to develop. These diamonds are brought closer to the Earth’s surface through volcanic eruptions and are found in volcanic rock formations known as kimberlite pipes. However, only a tiny percentage of these pipes contain diamonds in quantities that make mining economically viable, adding to the rarity and value of these gems.
From Rough to Refined
- Rough Assortment: Once mined, diamonds are categorized based on their unique characteristics such as colour, clarity, and carat weight. Expert sorters assess each rough diamond’s potential, separating the highest quality gems from the rest.
- Planning and Cleaving: This stage involves visualizing the diamond’s final shape, size, and carat weight. Natural facets, like minor inclusions, are strategically planned to enhance the diamond’s overall beauty. Cleaving involves splitting the diamond along its natural planes to achieve the desired shape.
- Blade Sawing and Laser: Diamonds are cut precisely using blade or laser sawing techniques. Laser sawing offers extreme precision, while blade sawing involves a rotating blade coated with diamond dust.
- Bruting: The process of bruting or girdling is employed for round brilliant diamonds. This involves grinding two diamonds against each other to achieve a round shape.
- Polishing: The diamond’s facets are meticulously cut and polished. The initial phase, known as blocking, sets the standard for the diamond’s brilliance. Larger diamonds undergo a second phase called brillianteering, where additional facets are cut to maximize the diamond’s fire and sparkle.
- Final Inspection: Each diamond undergoes a thorough inspection to ensure it meets the highest quality standards. It is then graded based on the 4C’s: Cut, Clarity, Colour, and Carat Weight.
Certification: A Mark of Authenticity
Diamonds, especially those above 0.30 carat, are sent to reputable gemological laboratories like the Gemological Institute of America (GIA) or the International Gemological Institute (IGI) for certification. This certification acts as a stamp of the diamond’s authenticity and quality. At Soham Ghosh International, diamonds under 0.30 carat can be certified upon request. This service is complimentary, you will not have to bear any additional charges for the same.
