OUR MANUFACTURING PROCESS
At D.Navin, we take immense pride in our in-house diamond manufacturing process, which transforms responsibly sourced rough diamonds from industry leaders such as, Rio Tinto and De Beers Group into beautiful diamonds. Our craftsmanship ensures each diamond's brilliance, clarity, and quality. Here's an overview of our step-by-step process:
We begin by responsibly sourcing our rough diamonds from trusted mining companies such as Rio Tinto and De Beers Group. Our commitment to ethical and sustainable practices ensures that our diamonds have a transparent and responsible supply chain.
Our experts categorize the rough diamonds based on size, shape, and quality to strategize the best polishing approach.
CLEAVING & SAWING
Using precision tools, we execute the cutting process, either by cleaving (splitting) or sawing, to create smaller pieces known as "roughs."
Our skilled artisans develop a comprehensive facet plan, and then use employ state-of-the-art cutting machines to meticulously cut and polish each facet, including the table, crown, girdle, and pavilion facets.
We subject the polished diamond to thorough scrutiny under magnification and specialized lighting to identify any imperfections or flaws.
Each polished diamond is thoughtfully and securely packaged, ready for shipping, external certifications or presentation to our valued customers.
After sourcing, we carefully examine the rough diamonds, evaluating their potential while identifying any flaws, inclusions, or unique characteristics.
We mark each rough diamond to determine the optimal orientation for cutting, aiming to maximize yield and brilliance.
We refine the rough diamond's shape by meticulously grinding away excess material from the edges. Then we use our bruting machines to shape the diamond into its fundamental form.
Using a carefully selected abrasive, we gently grind and polish each facet of the diamond, enhancing its brilliance and clarity.
Our experts assign a precise grade to each diamond, adhering to the "Four Cs" (carat weight, cut, color, and clarity).
Our diamonds are carefully distributed to all of our sales offices around the world some of which include; Mumbai, New York, Dubai, Antwerp, Hong Kong and Shanghai.
