Synthetic Diamond Detection Course

 IIDGR diamondview 2044x1533

Colleagues attending this short course will:

Review detailed information about HPHT and CVD production methods and any subsequent identification features that subsequently occur; Review De Beers screening and verification instruments, for when visual detection is no longer possible.

The course will highlight the benefits of commercially applying the knowledge learnt during this course, to further enhance business decision making whether that be the employment of testing or referral services, or the purchase of new instrumentation.

Participants take away slide packs to help them retain the knowledge learnt on the day of the workshop, as well as a De Beers tweezer/loupe kit and Certificate of Completion which also states its CPD certification.

When & Where

10 Vyse Street, Birmingham, B18 6LT



Course Programme

The course includes a variety of practical exercises where students spend time studying a wide range of specially selected products including HPHT and CVD Synthetic Diamonds as well as simulants. Animations are also used to explain the growth processes of both HPHT and CVD synthetic diamonds, and hands on use of screening and verification equipment is also included.

Tutor Name and Biography

The course tutor, Samantha Sibley has worked at the De Beers Group of Companies since 1992.  She has an HNC in Physics and gained the Gem Diamond Diploma from the Gemmological Association of Great Britain in 1996.  She has experience in microscopy, sample preparation (lasering/polishing) and spectroscopy.  She is involved in using spectroscopic techniques such as infrared absorption and photoluminescence to investigate properties of natural, synthetic and treated diamonds.  This work has resulted in a number of publications in both gemmological and scientific journals.  Her current role is focussed on providing technical presentations related to consumer confidence issues, instrument training and workshops both internally and for the wider diamond trade.

Prior Knowledge and Experience

It is recommended that students have a working knowledge of Diamond morphology.

Experience using a microscope, and handling polished diamonds is essential


All equipment is provided for the student including a workstation containing a microscope, daylight lamp and sorting pad. All sample goods are provided as well as all written materials. A tweezer/loupe kit is also provided for participants (which the participant can take away with them).
