As an introduction to handling diamonds, this short course will build on your knowledge of gemstones and, in particular, diamonds. Practical Diamond Grading (PDG) together with Advanced Practical Diamond Grading (APDG) are the practical components of the Diploma in Diamond Technology (DipDT). Practical instruction is delivered by acknowledged diamond experts who will teach you the use of professional instruments in the laboratory.

This intensive short course builds on the knowledge and experience you’ve gained in Practical Diamond Grading and extends the principles learnt in assessing round brilliant cut diamonds to the fancy shapes. It also extends your knowledge of diamonds by teaching you about what can be done with damaged diamonds and their salvage potential, how to approach and evaluate antique diamond cuts, grading colour of fancy coloured diamonds and how to recognise and identify the newest CVD and HPHT synthetic diamonds.

This one day course introduces a range of coloured gemstones. We will discuss identification, properties, country of origin issues and care for specific gems. Synthetic, treated and imitation gems will be discussed. Also how we test for identification and we will show you.
