Diamonds are one of the hardest substances known to man and, owing to their sparkling nature; they are most popularly used for making jewellery. Due to its other desirable properties, diamonds are also used in various industries for cutting and grinding. The diamonds that we see in jewellery pieces in its exquisite state is not how it was recovered originally. The diamonds undergo a lot of processing by skilled workers to appear as they do in a ring; regal and impeccable. Here is how diamonds are processed to be used in jewellery.
Diamonds are recovered from an ore called kimberlite. This ore is transported from the mining areas to a processing plant where they are gently crushed to obtain smaller pieces of the ore which are roughly 25mm in size. These smaller pieces undergo screening and scrubbing to remove to the extremely small particles and to wash off the dust and unwanted dirt around the diamond stone. At this stage the diamonds usually look like a pale glass rock. These pale glass rocks then undergo X-ray scanning to identify the diamonds which are then retrieved using grease tables or grease belts. Diamonds are hydrophobic, hence they stick to grease while the unwanted mineral concentrate gets washed off. This process yields a rough stone of diamond which is then cut and polished by skilled workers. Hatton gardens jewellers are one of the experts in this field and provide a professional work in polishing.
The rough diamond stone undergoes a number of phases at the hands of the skilled workers in order to be a part of the Hatton Garden Jewellery. First the rough stone is cored using a laser to obtain a fine diamond structure. This structure is then sectioned delicately by laser cutting to obtain thin slices of diamond. Then an expert in diamond cutting plans and draws the shape of the desired diamond in the slices by the help of computer aided designing and then cleaves or saws the diamond. This requires a lot of skill in order camouflage the inclusions in the final piece and to cut the stone as economically as possible.
In the next phase called bruiting, the pavilion of the diamond is shaped, which is the noticeable V shape beneath the girdle of the diamond. Bruiting was done manually in the past, but today it is done mechanically using laser beams for a more precise cutting. After bruiting, the polishing of the diamond is done in which the diamond is polished to its final brilliance by giving facets to its structure. The numbers of facets determine the degree of sparkle of the diamond. For example, a round cut diamond has around fifty sever facets in total: 33 facets above the girdle and 24 facets in the pavilion. The polishing of the diamonds yields a smooth surface after which it is cleaned thoroughly in acids to give it its final form which is used for making jewellery.
It requires great precision and skill to convert a rough diamond to a brilliant diamond in its full glory. The diamond engagement rings Hatton Garden rings and other diamond jewellery look stunning and exquisite because of all the hard work that goes into making them.
