… the jewellery is really good and the staff were so friendly and professional. I left the shop with a beautiful onyx ring that will forever remind me of my time spent in Cambodia :). If I had more time here I would have loved to try out the workshop to make a ring myself!

… It is absolutely worth visiting the Gemological Institute, and all the staff members are very professional, kind, patient and explain each gem of interest to you. I will certainly return to Siem Reap and purchase a gem from here on my next visit. 5 stars!

… I got a very interesting visit and learn a lot about the different varieties of gems.

I did not know about the different stones and gems in Cambodia. Nice things to do besides the temple.
