Precious stone cutters use cutting machines and tools to cut or carve diamonds and other gemstones according to diagrams and patterns while considering different specifications. They are experts at fabricating jewellery such as rings, brooches, chains and bracelets from gemstones.
Gemstones can be cut into different shapes such as faceted stones, cablochons, spheres or beads. They can also be fit together with other precious stones or different materials as in the case of inlays or mosaics. Finally, they can be carved to produce intaglios or cameos.

Closely examine gemstone surfaces using polariscopes or other optical instruments.
Shape gemstones using equipment such as diamond or silicon carbide wheels to obtain a rough though more regular form called the preform.
Record the weight of finished jewellery pieces.
Handle, modify, or repair jewellery-making equipment such as jigs, fixtures, and hand tools such as scrapers, cutters, gougers, and shapers.
Use electronic, mechanical, electric, or optical precision tools, such as drilling machines, grinders, gear cutters and milling machines to boost accuracy while machining products.

Reshape, re-size and polish jewellery mountings. Customise jewellery according to customers' wishes.
Select and apply appropriate restoration techniques in order to achieve the required restoration goals. This encompasses preventive measures, remedial measures, restoration processes and management processes.
Clean and polish metal items and pieces of jewellery; handle mechanical jewellery-making tools such as polishing wheels.
Create pieces of jewellery using precious materials such as silver and gold.
Report in case the product arrives with a defect from previous processes. Understand the type of defect and send it to the right person.
Develop new jewellery designs and products, and modify existing designs.
Estimate the total cost for the maintenance of watches or pieces of jewellery.
Estimate the cost implications of restoring and replacing products or parts.
Assess used metal (gold, silver) and gems (diamonds, emeralds) based on age and current market rates.
Evaluate the outcome of conservation and restoration procedures. Evaluate the degree of risk, success of treatment or activity and communicate the results.
Use cleaning equipment to properly care for jewellery and watches, as per customer request. This might involve cleaning and polishing watches and pieces of jewellery.
Apply enamel paint on surface using brushes.
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.
Record the amount of time it took to process an item of jewellery.
Make jewellery repairs, such as enlarging or reducing ring sizes, soldering pieces of jewellery back together, and replacing broken or worn-out clasps and mountings.
