Our  Piece  of  Advice. Your  Peace  of  Mind
What We Do

Big Lab Research provides a range of gemological appraisal services. 

Each case is handled personally by our in house gemologist. We test, authenticate and generate detailed certificates and report for every piece of previous gemstone or jewelry we appraise. 

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.
