OIGS Laboratory
Independent gem testing with clear, practical reports
OIGS Haridwar examines gemstones, diamonds, jewellery and rudraksha with a simple goal: give buyers, jewellers and students reliable information without buying or selling the submitted items.
Testing, valuation and training under one roof
Gem identification, diamond basics, jewellery valuation support, rudraksha testing and hands-on gemology courses.
Why testing matters
Know what you are buying, selling or submitting
Gemstone appearance alone is not enough for a confident decision. A laboratory examination helps identify the material, observe important features, document the item and explain the result in language that a client can understand.
Our role is to examine and explain. OIGS reports and consultation support are designed for practical use in jewellery purchase, resale, insurance, education and trade documentation.
Identification
Quality observations
Report guidance
