FINE JEWELLERY MAKING

Competition Overview


A fine jeweller would normally work within a small specialist workshop creating high quality pieces of jewellery from a working drawing or to a customer’s specification. This requires using a range of hand tools, and traditional techniques, often referred to as diamond mounting. He/she will have the skills to work accurately to given dimensions and have comprehensive knowledge of precious metals and processes. The economic use of high value materials and the ability to recycle precious metal is fundamental to the work of a fine jeweller.

The project for the National Qualifiers is a timed assessment, designed to measure the core skills needed to take part in the UK National Final.

Participants will have received a briefing and competition guidance in these core skills prior to doing the assessment project but will not be able to see the design beforehand.
Participants will be expected to complete a test project live National Qualifier in the given time and demonstrate the appropriate skills needed to produce fine jewellery to the standard required at national competition level.
This competition is intended for those competitors with a minimum of 1 year full time training experience of this skill in education, training, employment, or who are enrolled in a programme of study or have completed the equivalent to level 2 qualifications and are now working towards a higher level.
It is recommended that competitors have undertaken specific training in diamond mounting and are confident with basic jewellery bench equipment, processes such as soldering and piercing as well as working from technical drawings.

Task Breakdown


The competition is designed to test the practical competence of jewellery makers.
Entrants will be asked to complete a task which will involve making a piece of jewellery to given dimensions within a specified time period. The competitors will be judged against the broad assessment criteria and their ability and skills to construct a piece of jewellery accurately to a drawing through traditional diamond mounting techniques and economic use of material.
Entrants will receive support and guidance before undertaking the timed assessment.
Selection for the UK National Finals is based upon the marks achieved during the National Qualifiers. Additional training is provided in preparation for the finals.
Candidates should be aware of the following:

  • Standard silver sheet and wire appropriate to the requirements of the test will be provided, the weight of which will be recorded against each competitor’s name at the beginning of the test.

  • Candidates should bring their own hand tools; solders and fluxes; preferred solder supports; abrasive papers; mops and burrs; hand held propane torches if required.

  • The workshop will be equipped with gas/air torches at the bench plus larger torches at the hearths with bricks on a turntable, pickle, ultra-sonic cleaning and polishing facilities, micro-weld machine and flexible shaft pendant motors.
