About the Lab

Where Science Meets Trust

Using modern X-Ray Fluorescence (XRF) technology, we test gold, silver, and other precious metals quickly and without causing any damage to your jewellery. Whether you are a jeweller, an investor, or an individual — our results give you full confidence in what you own.

Our trained professionals follow the highest standards of honesty and care. Every test result is explained clearly so customers understand exactly what they have. We believe that trust is built through transparency.

We also help educate people about hallmarking, karat values, and gold purity — so that more buyers and sellers can make informed decisions.

Process

How the Testing Works

Walk In

Visit our lab at Hazari Market, Chattogram. No appointment needed — we serve walk-in customers every day during business hours.

Place & Scan

Your jewellery is placed inside the XRF machine. In seconds, X-rays analyse the metal composition without any physical contact or damage.

Get Results

Full Confidence

Walk away with complete knowledge about your gold. No guessing, no doubts — just science-backed certainty about your investment.

Why Us

Why Choose Our Lab?

Zero Damage Testing

Your jewellery is never cut, scratched, or melted. XRF technology reads the metal composition from the surface — completely non-invasive.

Honest Reporting

We report exactly what the machine reads — no inflating or deflating results. Our reputation is built on honesty, not favour.

Fast Turnaround

Most tests are completed within seconds to a few minutes. No long waiting periods — get your results and move on with confidence.

Customer Education

We don't just hand you a number — we explain what it means, how karat values work, and what to look for when buying or selling gold.
