Diamond processing enterprises. Processing diamonds into brilliants.
The catalog of the international portal presents stone processing companies in Russia. The indestructible mineral diamond is widely used in industry and jewelry. Drills and cutters, precious jewelry, and souvenirs are made from it. The stone is also used to create computers and in nuclear production.
An important branch of the gemstone market is the export of minerals to international markets. After the rough diamonds are processed into polished diamonds, they are delivered to trading floors in Tel Aviv, Antwerp, New York, Dubai, and Hong Kong. Stones for export are packaged in bags, sorted by color, weight, diameter, and other parameters.
The price of the finished product depends on the diamond cut shape, weight, presence of defects, and quality. In the process of processing rock, from mining or creating a mineral to selling it on the market, a lot of specialists work with it – peelers, markers, sawers, grinders, etc. The work of craftsmen inevitably affects the cost of the final product.
Stone processing
A natural diamond is an uncut diamond, an untreated crystal that turns into a magnificent stone in the hands of a master. The mineral acquires particular value after processing. First it is weighed on a scale. Then they examine for defects and determine how the diamond is cut. After analyzing the quality of the workpiece, the specialist draws up a processing plan to eliminate errors and at the same time maintain the weight of the stone.
The method of cutting a diamond depends on the characteristics of the raw material. If the workpiece has the shape of an octahedron (octahedron), the stone is cut into 2 parts with a saw with a diamond edge. The resulting products are machined to a classic round shape. After all the manipulations, a geometrically regular polyhedron should emerge from the master’s hands.
Classic diamond cutting involves creating a round stone. Additionally, craftsmen create minerals with fancy geometries – square, oval, triangle, heart, etc. Diamonds are cut into brilliants by qualified craftsmen. Their task is to give the stone a beautiful shape while minimizing losses. During processing, the mineral loses on average from 55 to 70% of its mass.
If the stone is not octagonal, but has a more complex shape, its processing is entrusted to the most experienced craftsmen who are capable of processing blanks with a huge number of facets – up to 240. The quality of diamond cutting affects the cost of the diamond, so the procedure is entrusted to qualified specialists. The price of the stone is also affected by the purity of the crystal (the absence or presence of defects and foreign inclusions), color, weight (measured in carats).
