Great video training! I have retained learning most from the video with Tanja. Many thanks!
- Lee Kim G. (Singapore)
I really liked how the video materials can be seen , touched and observed during the practical sessions in class. The class size was also kept in a small group so that we could have more time to interact with our instructor.

A great place to understand gems. It is really practical and useful... I would like to apply what I have learnt in buying the gems/ jadite or pearls when the occasion arises.
- Davi B. (Singapore)
Excellent course!!! Highly recommended...Very well prepared and paced
- Yiming L. (Singapore)
Good knowledge and hands on. Great instructor who has a vast knowledge of the gems and industry. I have become more knowledgeable, less skeptical to scams to buying gems and increased basic knowledge to mining, gems and the environment.
- Jasmine L. (Singapore)
The material is well-written. Very informative. The trainer is a subject matter expert and imparts a lot of knowledge to us. The training administration is seamless and makes the registration process very smooth. Staff is friendly and prompt. (I will use the skills) to start a business & buy gems with more knowledge.
- Moy Yin L. (Singapore)
Perfect class size. Love the face to face lessons, the physical examples for reference and learning, and the interactive lessons. The online lessons were well organised too! The videos were clear and well paced. The online notes and physical notes were very helpful too! I like the fact that we can always log back onto the learning platform to recap moving forward. Thank you to our trainer, Tanja too! Very engaging, clear communication, knowledgeable!
- Pauline S. (Singapore)
The course is great, even for beginnners. Very very informative and makes us understand very well with lots of examples. Only small improvement will be for the instructor to take note of the time of the physical class as sometimes the class can overrun, especially when students start to ask a lot of questions.
- Kai Xuan Y. (Singapore)
A very good learning experience. Lots of practical application. Great instructor who is very experienced and able to communicate concepts effectively.
- Su Ean H. (Singapore)
Fantastic and very professional. Small class size and great teacher. They cover a lot of things and the online courses were easy to grasp and fun. The assessment was necessarily difficult and very helpful for remembering. One of the best courses I have taken.
- Fuling S. (Singapore)
It has been an incredibly rewarding experience to be part of this class. The training materials are very comprehensive and the effort that has gone into producing them deserves a huge compliment. Being able to touch, feel and assess the gems in class with classmates has made the lessons truly come to life. Tanja deserves nothing less than the utmost compliments I can give to a trainer, hands down the best trainer I’ve encountered in any SkillsFuture course to date.
- Pamela P. (Singapore)
It is an excellent course to attend for those who enjoy gemstones, diamonds, jade as well as phenomenal gems. It can be very useful in buying gemstones and how to read and understand gem and diamond certificates.
- Julia N. (Singapore)
Informative course! Please attend if you have keen interest in gems and diamonds! I collect crystals and make bracelets so going through this course helps me in my purchase of the materials!
- Cindy W. (Singapore)

This is such a Great course with very solid content knowledge to be acquired! I can talk to my husband about the gems and Jade now as he is a huge fan of these gemstones.

It was a wonderful course and I have learned a lot, this is definitely a good start to the world of gemology. My family members are avid gem collectors and the knowledge I gained would come in handy during our gem hunt.
- Ee K. (Singapore)
This will be useful for my e-commerce store.
- Fannie T. (Singapore)
I only wish we had more time to look, see and feel more samples of the gems. Otherwise I thoroughly enjoyed myself. It gives me an impetus to learn more about this industry and what it has to offer.
- Claudia G. (Singapore)
Highly recommended! It's good to have time set aside in the week to properly digest the videos. It contains the broadest scope of coverage - appropriate given the current consumer interest.
- Joanne O. (Singapore)
I definitely like this training with good and useful knowledge learnt. It will be good if we have more time to practice during the class... Thank you very much for the training and SkillFuture claimable is also an helpful factor. Thank you.
