jewellery processes
Materials and processes involved in creating jewellery items like earrings, necklaces, rings, brackets, etc.
Jewellery polishers ensure that finished jewellery pieces are cleaned by customer demand or prepared for sale. They may also perform minor repairs. They use either hand tools such as files and emery paper buff sticks and/or hand held polishing machines. They also use mechanised polishing machines such as barrel polishers.

The different processes, or motions, used in polishing, depending on the desired end result concerning the level of smoothness and shininess of the metal workpiece: cut motion or colour motion.
gemstones
Types of minerals or petrified materials that are cut and polished for use in jewellery, classified according to type, characteristics, and value.

Sector-specific
6 competencesclean jewellery pieces
Clean and polish metal items and pieces of jewellery; handle mechanical jewellery-making tools such as polishing wheels.
ensure conformance to jewel design specifications
Examine finished jewellery products to ensure that they meet quality standards and design specifications. Use magnifying glasses, polariscopes or other optical instruments.
grind gemstones
Shape gemstones using equipment such as diamond or silicon carbide wheels to obtain a rough though more regular form called the preform.
polish gemstones
Use polishing agents or fine grades of diamonds to remove small amounts of stone in order to get a shiny surface that will improve light refraction or reflection.
sand gemstones
Use abrasives to remove scratches and irregularities on gemstones. The abrasives used for this process are finer than the ones used for grinding gemstones. The sanding process used to create flat surfaces on a stone, such as facets, is called lapping.
use jewellery equipment
Handle, modify, or repair jewellery-making equipment such as jigs, fixtures, and hand tools such as scrapers, cutters, gougers, and shapers.

precious metal processing
Various processing methods on precious metals such as gold, silver and platinum.
Cross-sector
2 competencescoining
The process of shaping metal parts with a high relief or very fine features, such as coins, medals, badges or buttons, by pressing the surface of the metal between two dies.
cultured pearls
The process of creating pearls by inserting a piece of tissue in the centre of the oyster to help create pearls under controlled conditions, instead of the accidentally occurring natural pearls.

12 competencesapply polishing lubricants
Apply the appropriate lubricant matching the kind of metal of the processed metal workpiece during polishing processes, such as was or kerosene.
mark processed workpiece
Inspect and mark parts of the workpiece to indicate how they will fit into the finished product.
measure flatness of a surface
Measure the evenness of a workpiece's surface after it has been processed by checking for deviations from the desired perpendicular state.
metal polishing machine parts
The various parts, their qualities and applications, of a metalworking machine designed for buffing and polishing metal surfaces, such as the brush head, contact roller head, drum, drum base, lock bar, shell, and others.
monitor moving workpiece in a machine
Monitor the processing of a workpiece in motion, such as a piece of metal or wood moved linearly over a static manufacturing machine.
operate metal polishing equipment
Operate equipment designed to buff and polish metal workpieces, such as diamond solutions, silicon-made polishing pads, or working wheels with a leather polishing strop, and others.
operate precision measuring equipment
Measure the size of a processed part when checking and marking it to check if it is up to standard by use of two and three dimensional precision measuring equipment such as a caliper, a micrometer, and a measuring gauge.
remove inadequate workpieces
Evaluate which deficient processed workpieces do not meet the set-up standard and should be removed and sort the waste according to regulations.
remove processed workpiece
Remove individual workpieces after processing, from the manufacturing machine or the machine tool. In case of a conveyor belt this involves quick, continuous movement.
set up the controller of a machine
Set up and give commands to a machine by dispatching the appropriate data and input into the (computer) controller corresponding with the desired processed product.
digital
supply machine
Ensure the machine is fed the necessary and adequate materials and control the placement or automatic feed and retrieval of work pieces in the machines or machine tools on the production line.
tend metal polishing machine
Tend a metalworking machine designed to buff and polish metal surfaces, monitor and operate it according to regulations.
