Helped me a lot in identifying B+C Jadeite (chemically bleached and colored jadeite) that was imitated well and bad for health. Learned a lot from Gary, and that nowadays scams are getting better and better. The scammers actually issued certificate that certified the item is a jadeite but state nothing about whether the item is a type a jadeite (natural jadeite without undergoing through treatment)

Pleasant experience with Gary and his colleague, I had dropped by to get my wife's jade pendant assessed and from the experience, also gained a fair bit of knowledge as a layman to identify jade (jadeite) from both gentlemen.

Great experience with Gary and his team. I got my jade bangle assessed and I also got to learn a lot more about gemstones and what I want for my engagement ring. Hopefully will come back for the ring š«¶ ā¦

I came to Raffles GemLab for their gemology services - specifically, for gemstone testing and appraisal. The two gentlemen who attended to me were very patient and understanding with regards to my needs, and were honest, transparent, and highly professional. Overall, it was a great experience and Iād highly recommend them not only for their exquisite selection of gems and jewelry, but also their gemological services!

Raffles Gemlab was selected randomly on Google to process a Jade analysis report. Mr Gary explained the fields of analysis clearly before conducting the tests. Service is trusted and efficient, the detailed report was ready within an hour. Being an ordinary consumer, I had gained much knowledge and insights. Much appreciated and will definitely return if I need the service again. The company also retails a wide range of interesting jadeite and gemstone pieces.
