What Customers say

So far, I have sent more than fifty gemstones (diamonds and other precious gemstones) to Big Lab Research for both examination and appraisal valuation. Their prompt and professional services are unbelievable and tremendous! To date, I received 'zero mistakes' of the gemstone examination. Their decades of experiences and up-to-date knowledge in gemstones treatment technology has won them the name of 'Doctor of Gemstones', which my company has given them. I would like to send my greatest attitude to both Mr Ben and Mr Kevin for their excellent work in the gemstones industry. I would strongly recommend anyone who wish to engage their professional services. Thank you.

Basically, they provide certification services for all kinds of Gems and I’ve got my 100++ year old jade (Jadeite) for their appraisal/certification. Ben is very experience and has his whole life dedicated to the purchase/sale/certification of jewelleries and gemstone. His partner, Kevin whom we first contacted was very friendly and approachable (He is also GIA certified). The appraisal process took less than an hour and the certificate is very professional. I completely recommend them to you should you need these services.

I brought in 24 pieces of jewellery for Ben and Kevin to perform gemstone identification. They were fast and professional. What i liked about them is also that they were very friendly and approachable - makes it easy for me to clarify any question i have about the gemstones. I could also tell from my interaction with them that they are very experienced gemologists so would definitely recommend their services. :)

Just received back my Sapphire gemstone from Kevin and Ben. I have to say, at first it didn't look like their retail is 5 stars worth. But I was proven wrong. Their service is superb. Not only were they very quick in identifying and generating the gem report, they also answered all my questions very intelligently. They were very patient. Kevin, the one who helped identify my stone, went on to answer some of the questions I had even after I left the store. Great and efficient service! Will surely recommend their service to whom I know needs it.

Kevin and Ben are definitely few of the best you can find in the market to get your gems certified with quick turnaround time. Both of them are experienced and specialised and are able to advise us accordingly. Learnt quite a bit from Kevin during my conversation with him. Highly recommended! Do drop them a text before you head down to make sure they are around or so that they can set aside a time to attend to you.
