Course Outline

Practicals

Overview

Practical sessions are integral to developing hands-on skills in diamond grading, inspection, pricing, and negotiation. Learners will use professional equipment (loupe, scale, colour comparators) to grade diamonds, evaluate parcels, and simulate buying/selling transactions under supervision.

Practical Activities

• Diamond Grading Practicum — Learners grade a set of 10 loose diamonds for carat, colour, clarity, and cut using loupe, scale, and master stones, and record results on grading sheets. (6h)
• Pricing and Valuation Exercise — Learners use the Rapaport Price List and current market data to calculate prices for graded diamonds, considering premiums/discounts, and compare with actual market offers. (5h)
• Mock Buying Negotiation — In pairs, learners role-play as buyer and seller negotiating a parcel of 5 diamonds, with a focus on inspection, price negotiation, and closing terms. (5h)
• Mock Selling Presentation — Learners prepare and deliver a sales pitch for a specific diamond to a simulated retail client, highlighting 4Cs, value, and ethical sourcing. (5h)

Summatives

Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.

Practical Assignments — 30%

Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.

Daily Exercises — 20%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.

Final Test — 50%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.

Final Total
