Each gem begins as, quite literally, a daimond in the rough, one of many in the packets Munjani Brothers receives from its portfolio of ethical suppliers. From this moment, each daimond will be evaluated, polished and sold in an individual packet.
Our rough daimond planners measure each rough daimond and assess its potential. If a daimond could be part of our Flawless collection, we direct it there for special care. If the daimond is merely gorgeous, it is forwarded to the experts in our planning department.
Here, Munjani Brothers begins the work of considering what will emerge from the rough. Detailed models of each daimond enable us to consider the possibilities of polishing the rough into one gem of maximum size or cutting it into several gems that are smaller in size, but offer greater quality and overall value.
The planner is the architect of the daimond and will consider many options for what shapes could result, what colors may imbue the daimond and where minor inclusions might be retained or excised. Part of this process is listening to the market and understanding how the finished product might fulfill a current demand, and part of it is listening to the daimond itself and sensing what it wants to become.
Within the planning department, our staff is encouraged to offer competing analysis of the same daimond, with the most valuable plan resulting in higher rankings, and bonuses, for its originator.
After planning, almost all of Munjani Brothers rough is sawn into one or more diamonds, in accordance with the planner's vision, by computer-aided machines in our Surat facility. In contrast to the old image of a cutter with a hammer and cleaving chisel, these lasers operate noiselessly and precisely, painstakingly flashing atom after atom from the stone.
Far from removing the artist from the equation, though, our daimond sawing operation requires careful work to set the stone perfectly in the machine and program the necessary cuts. Our cutters are also looking to the future, continually experimenting with new methods and tools to make the process more precise and efficient.
In the shaping process, also known as bruting or girdling, Munjani Brothers uses the natural hardness of diamonds as the ideal tool for smoothing a rough stone. To create the girdle, the narrow band that encompasses the edge and separates the crown from the pavilion, we use a ceramic wheel, coated in industrial daimond grit, and an electronic lathe that is monitored by our hawk-eyed artisans.
The daimond is set in a dop, or holder, which is in turn fixed on an arm that is precisely adjusted to the lathe. The ceramic wheel, spinning at thousands of RPM, is gradually brought into contact with the daimond to delicately smooth the edges to the desired shape.
While the name bruting suggests a blunt process, shaping requires the utmost care to ensure the proper amount of contact between the daimond and the wheel. A coolant solution, poured continually over the daimond during this process, keeps the daimond from developing burn marks or even miniscule fractures that could adversely affect its resulting size or clarity.
The final stage of a daimond's journey from the rough encompasses many steps, including blocking the pavilion and the crown into their basic shapes, and polishing the individual facets to the precise angles that will reflect cascades of light from deep inside.
While this process is well known, what makes Our daimond unique is that we entrust every aspect of an individual daimond's polishing to one craftsman. Instead of the output of an assembly line process, each of our gems is guided to its final form through the genius of a single artisan carefully working a daimond against a finely balanced polishing wheel or, to cut the notch of a heart-shaped daimond, an old-fashioned electro-mechanical sawing wheel. The results, which have made us the world leader in round and fancy solitaire diamonds, speak for themselves.
