Course preview

Millions of laboratory-grown diamonds are being released into the jewellery market every month.  Contradictory to common belief, the majority of these have high colour grades (D-E-F), great clarities (VS2 and above) and can be very difficult to detect.

Although a lot of these diamonds are sold with full disclosure regarding their origin, unfortunately, many are not.  Today's jewellery professional can find themselves face-to-face with these products on a daily basis.  The onus is on them to be able to detect and identify any possible laboratory-grown diamonds.

This brand new lab-grown grown course focuses on the production, treatment and identification of laboratory-grown diamonds.  The information available in this course goes beyond generic information available by many other gemmological institutions and packages it in easy-to-follow, entertaining format.

Become fully informed, up-to-date and confident in your knowledge of laboratory-grown diamonds with this ultimate online course.

What students are saying

A very well thought out and researched course that I really enjoyed! I feel most gemmological qualifications lack in the synthetic department but this course really helped build on the foundations I learnt during my FGA and DGA. It covers absolutely everything you could want or need to know about LGD's. I really liked the addition of the quizzes at the end of each chapter. Well done Julia for creating such a fantastic course with such great content!

Recent reviews

I thought the way the course was laid out was superbly well thought out. It was very user friendly, the videos are nice as it feels like you have a guide in Julia as you progress. The quizzes at the end of each section were great, as they make you think and log what you have learned. Thanks again Julia!

Wow! What a thorough and enjoyable course. I really feel like I have a far greater knowledge of synthetic diamonds now. Thank you Julia. Fantastic course and I feel much more confident in identifying lab-grown diamonds now.

 - Sammantha M, U.K.

OMG!! This was very challenging and interesting course!! I had to use translator, but I also learned new vocabulary at the same time. I am already a graduated gemologist D.G.Fin, in Finland. I got so much more confidence to discuss this topic now also with English speaking gemology colleagues. It appreciated being able to return back to repeat things. Thank you so much, Julia!! I can't wait your other future gemology extra education online course like this!

Moving onto Part 2 was a really enjoyable progression. It has certainly made me more aware of the features that I need to be aware of when looking out for Lab Grown Diamonds. The level of knowledge offered in this course is pretty impressive, and I am sure I will be re-visiting to refresh myself from time to time. Thanks Julia!

As a graduated gemologist in Finland, (D.G.Fin), I found this Ultimate Laboratory-grown Diamond Course very, very specific and useful to complete and deepen my professional knowledge in this field - also in English.

 - Teresa M H, Finland.

A very enjoyable course.  A great deal of detailed information that has been well thought out and presented in a logical user friendly manner, leading well from one chapter to the next. The use of quizzes throughout help to assimilate the information and the final test is definitely exercise for the brain.  Thank you Gem Academy.
