Study diamonds online for the the comfort of your own home

Course Information

The Essentials for Rough Diamond Evaluation & 5-Day Lab is a blended learning programme designed to give learners a strong foundation in diamond identification, evaluation principles, and practical application.
This programme is divided into two components:

Module 1: Online Theory

Delivered through our interactive online learning portal, the theory module includes:

· Instructor-led video lessons

· High-resolution images and diagrams

· Interactive quizzes

· Guided reading and assessments

· Scheduled virtual consultations with lecturers

Learners can complete the theory component at their own pace within a 3-month access window. Successful completion of the theory module is required before attending the practical lab.

Module 2: 5-Day Practical Lab

Held at our training centre, this hands-on lab applies the theory to real-world practice.
During this module, learners work with a wide selection of natural rough diamonds and selected gemstones.

Students learn how to assess rough diamonds using the 4Cs:

· Clarity

· Colour

· Cut potential

· Carat-weight

By completing both modules, learners will be able to identify a diamond, estimate its characteristics, and determine a market-relevant value for individual stones or parcels.

All tools and equipment required during the practical phase are supplied (remain school property).
