Diamond Gemstone Modelling And Optimal Processing Techniques Training

Learning Outcomes

• Apply 3D modelling software to create accurate digital representations of rough diamond gemstones.
• Analyze diamond internal and external characteristics to determine optimal cutting orientations.
• Evaluate different processing techniques to maximize carat yield and gemstone value.
• Design optimized cutting plans using advanced simulation tools.
• Implement processing workflows that minimize waste and enhance diamond quality.
• Demonstrate proficiency in interpreting modelling outputs for production decisions.

Target Audience

This course is designed for diamond graders, gemologists, jewellery designers, and processing technicians who wish to enhance their technical proficiency in diamond modelling and processing optimization.

Prerequisites

None — open enrollment

Course Outline

Practicals

Overview

Hands-on practicals are integral to this course, allowing learners to apply modelling techniques using professional software. Practical sessions reinforce theoretical concepts and build competency in creating, analysing, and optimising diamond gemstone models.

Practical Activities

• Basic Modelling and Software Familiarisation — Learners create simple diamond shapes and practice software navigation. (6h)
• Modelling Standard and Fancy Cuts — Learners model a round brilliant and one fancy cut diamond, applying correct proportions and symmetry. (10h)
• Inclusion Simulation and Light Performance Optimisation — Learners add inclusions to models and run ray tracing simulations to optimise light performance. (8h)
• Capstone Project: Rough to Polished Modelling — Learners complete a full project from rough diamond model to polished, optimised gemstone, including grading and presentation. (8h)

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

Component	Out of	Weight
Practical Assignments (rubric-scored)	100%	30%
Daily Average (multiple choice)	100%	20%
Final Test (multi-answer multiple choice)	100%	50%
Final Total	—	100%

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

How it works

• Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
• Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
• You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
• If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.

Where to find it

Sign in to the LMS, open your dashboard, and your certificates appear under My Certificates. Each entry has a View / Download button and a print option.
