Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a thorough risk assessment before commencing any polishing activity, including identification of hazards such as flying debris, entanglement, and inhalation of dust.
- Award credit for selecting and correctly fitting the appropriate polishing mop, compound, and machine speed for the metal and desired finish, justifying choices in relation to the component material.
- Award credit for consistently achieving an even, scratch-free finish without altering critical dimensions or detail on the component, as verified by visual inspection and tactile assessment.
Assessment Guidance
Guidance for achieving higher grades
- 💡Secure loose clothing, long hair, and dangling jewellery before using mechanical polishers; assessors frequently deduct marks for unsafe presentation.
- 💡Document each polishing stage in a personal logbook, noting the accessory, compound, and technique used—this demonstrates reflective practice and supports your decision-making if questioned.
- 💡Always use correct technical terminology (e.g., 'annealing', 'pickling', 'burr') to show depth of knowledge.
- 💡When answering design questions, justify your choices with reference to function, aesthetics, and material properties.
- 💡In manufacturing questions, include quality control checks at each stage, not just at the end.
Common Mistakes
Common errors to avoid in your coursework
- Confusing cutting and colouring compounds, leading to either excessive metal removal or an inadequate final polish.
- Applying excessive pressure or holding the workpiece at incorrect angles against the mop, causing burnishing marks, distortion, or component damage.
- Misconception: All gold is the same. Correction: Gold purity varies (9ct, 18ct, 24ct), affecting colour, hardness, and value. 24ct is pure gold but too soft for most jewellery.
- Misconception: Soldering and brazing are the same. Correction: Soldering uses lower temperatures and softer fillers, while brazing uses higher temperatures and is used for stronger joints; in jewellery, soldering is common for delicate work.
- Misconception: CAD designs are always accurate to the final product. Correction: Shrinkage during casting and finishing tolerances mean the final piece may differ slightly; allowances must be made.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on material properties and manufacturing processes. Create flashcards for key terms and practice identifying metals and their uses.
- 2Week 2: Practice CAD design using free software (e.g., Tinkercad) and attempt simple projects. Review past exam questions on design and manufacturing.
- 3Week 3: Work on calculation problems (density, cost, area) and gemstone setting techniques. Use online videos to visualise processes.
- 4Week 4: Attempt full practice papers under timed conditions. Review mark schemes to understand what examiners look for.
Exam Question Types
How this topic typically appears in the exam
- 📋Multiple-choice questions on material properties and terminology—read each option carefully; often two are close, so eliminate clearly wrong answers.
- 📋Short-answer questions asking to describe a process (e.g., 'Explain how to solder a joint')—use bullet points for clarity and include key steps.
- 📋Calculation questions (e.g., cost of materials)—show all workings and include units in your final answer.
- 📋Extended writing questions (e.g., 'Evaluate the use of CAD in jewellery manufacturing')—structure your answer with an introduction, balanced points, and a conclusion.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A jeweller is making a gold ring from 18ct gold (density 15.6 g/cm³). The ring has a volume of 0.8 cm³. Calculate the mass of gold needed, and then determine the cost if gold is priced at £45 per gram.
- 1.Step 1: Identify the given values: density = 15.6 g/cm³, volume = 0.8 cm³.
- 2.Step 2: Use the formula: mass = density × volume. So, mass = 15.6 × 0.8 = 12.48 g.
- 3.Step 3: Calculate the cost: cost = mass × price per gram = 12.48 × £45 = £561.60.
Question: A student is designing a pendant using a CAD program. The design includes a circle with a diameter of 20 mm and a rectangular hole of 5 mm by 3 mm. Calculate the area of the pendant (the circle minus the hole). Use π = 3.14.
- 1.Step 1: Calculate the radius of the circle: diameter = 20 mm, so radius = 10 mm.
- 2.Step 2: Calculate the area of the circle: A = πr² = 3.14 × 10² = 314 mm².
- 3.Step 3: Calculate the area of the rectangular hole: 5 × 3 = 15 mm².
- 4.Step 4: Subtract the hole area from the circle area: 314 - 15 = 299 mm².
