A laboratory built on light and proof
Luminex Identification of Gems reads the story written inside every stone — and puts it in writing you can trust.
The word Luminex means light — and light is how a gem tells the truth
Every gemstone carries a record of how it formed: the trace elements it absorbed, the inclusions it trapped, the way it bends and splits light. Read correctly, that record reveals species, origin and whether human hands have altered it.
We founded Luminex in Bengaluru — the heart of South India's gem trade — to read that record with rigour, and to hand traders, jewellers and collectors a certificate they never have to defend. Clear findings. Verifiable proof. Nothing hidden.
Three principles behind every report
Evidence over opinion
A grade is a conclusion, not a guess. We report only what the instruments and the eye can substantiate.
Independence
We buy and sell nothing. Our only product is an honest, unbiased assessment of what sits under the microscope.
Traceability
Every stone is logged, photographed and tracked from intake to sealed report, and stays verifiable for life.
Bring in your gem. Leave with certainty.
