About Us
GEM RESEARCH INDOLAB (GRI)
The Standard of Trust in Gemmological Science
Founded in 2018, Gem Research Indolab (GRI) is a premier, state-of-the-art gemological laboratory operating as a proud unit of Ratna Kamal.
GRI was established by the highly respected gemologist and prominent digital creator Mr. Yogendra Soni—the driving force behind Star Gemstone. Through his extensive and widely followed educational platform on YouTube, Mr. Soni has dedicated years to bringing transparency, deep market insights, and authentic awareness to millions of gemstone enthusiasts and buyers worldwide. GRI was born as the scientific extension of that very mission: to deliver absolute clarity, technical accuracy, and untampered trust to the gemstone industry.
Bridging Heritage and Science
In an era where sophisticated treatments, synthetic alternatives, and lab-grown stones are increasingly common, a gemstone certificate cannot just be an afterthought—it must be an unbreakable shield of security.
GRI perfectly bridges the gap between traditional gemstone trading and modern laboratory diagnostics. By combining decades of deep-rooted market knowledge inherited from Ratna Kamal with advanced testing instrumentation, we translate complex scientific data into definitive, easily understandable gemological reports.

"A gemstone report shouldn't just list technical specifications—it should give the buyer total peace of mind and an absolute guarantee of authenticity."
