The individual in the jewellery retailing store assesses the quality of the jewellery product through standard assaying methods, fixes its value and prevents fraudulent sales
This individual at work tests the gold alloy metal or jewellery through various assaying processes and stamps the hallmark. Assaying involves multiple stages of assessment to determine the proportion of gold in the alloy. After performing the assaying process and analyzing the results, the precious metal or jewellery is marked with internationally defined symbols and characters for hallmarking.
Individuals work with the auto-blocking machine and make the basic four (or eight) bottom and top facets of a diamond in order to make it ready for final polishing or brilliance. For auto blocking, the stone is set in a dop is fixed in the auto-blocking machine and held down on a revolving cast-iron scaife charged with diamond dust.
The individual works with bruting machine and another diamond or wheel (rotating in opposite direction to the diamond being bruted) to give the rough diamond round and cone shapes. A bruter must be careful: so that excess bruting does not cause too much stone loss or suboptimal bruting causes the girdle to disappear at a later stage of processing.
The individual on this job, allocates work to subordinate workers, trains and educates them, instructs about the job to be performed on daily basis, checks quality of output, manages team and systems, carries out performance appraisal and ensures safety of the diamond, in order to ensure accurate cut as per marking to derive maximum value from a rough as per company?s objectives and delivers on time.
The individual at work needs to cut the rough diamond along the marking by fixing it on to a dop or pot, then slicing it using the blade sawing machine. A blade sawing operator is responsible for delivering perfect cut roughs in the stipulated time, while minimizing weight loss and breakage.
The individual on this job, allocates work to subordinate workers, trains and educates them, instructs about the job to be performed on daily basis, checks quality of output, manages team and systems, carries out performance appraisal, ensures safety of the diamond, and interacts with other departments in order to ensure accurate basic four (or eight) top and bottom facets of the diamond as per company?s objectives and delivers on time.
Individuals working on this job place the finished diamond in a beaker with chemical solution like hydrochloric and sulfuric acid and place the beaker in a heating oven. This removes any residue of diamond dust, dirt or other contaminants collected during the cutting or polishing process. This process may also remove/bleach some of the darker surface reaching inclusions (Naats). Boiling this is sometimes performed on rough as well to improve the appearance of the rough.
The individual on the job work with bottom dop-tang system and make the 24 bottom facets of a diamond by polishing it on the polishing wheel or scaife in order to yield maximum brilliance and symmetry. For polishing, the stone is set either in a lead dop or a mechanical-clamp and held down on a revolving cast-iron scaife (horizontal and circular disc) charged with diamond dust.
The individual interprets the three-dimensional (3D) jewellery design, feeds design parameters in the CAM machine and produces resin based prototypes. The model prototype serves as a sample for manufacturing jewellery or components.
The individual in the retail store is in-charge of billing, collecting the payment from the customers and closing the sales transaction in a retail store. The individual also maintains records of sales transaction and other documents required for compliance.
The individual at work converts wax models to jewellery pieces through investment casting process. The individual invests the flask and then operates semi to fully-automated machines to pour and regulate the flow of molten precious metal into cavities created by melted wax, to produce cast jewellery pieces on mass scale.
The individual works with hand and machine tools and using gold and polished gemstones to create traditional and heavy Chettinadu jewellery, mostly acquired for investment or specific rituals.
The individual at work needs to cut the rough diamond into two pieces, for better value or the removal of impurities or irregularities without shattering it. The individual uses a second diamond or a laser, to carve a groove into the diamond along a plane of weakness. A steel blade is placed in the groove and a sharp blow is delivered with the hammer, which splits the stone
