Terms & Conditions

This website is operated by INSTITUTE OF INTERNATIONAL GEMOLOGICAL LABORATORY (IIGL), a sole proprietorship of JAI SINGH, referred to here as "IIGL", "we" and "us". By using the website, placing a testing order or enrolling in a course you accept these terms.

IIGL tests gemstones, diamonds and jewellery submitted by customers and issues reports and certificates, and offers gemology courses. Fees for each service are shown at the time of ordering or enrolment.

A report is a professional opinion on the item as it was when tested, by the methods and equipment available to us. It is not a guarantee of future value or a valuation unless it says so. We may re-test or amend a report if an error is found.

You confirm that you are entitled to submit the items you send, that the details you give are correct, and that you will not use our name, reports or report numbers in a way that misleads. A report's authenticity can be checked at any time on the Verify Report page.

Fees are payable in Indian rupees through the payment methods offered at checkout, and include GST where it applies. Testing begins once payment is received or the order is accepted by the laboratory.

We handle submitted items with care, but testing can involve risk to fragile or treated stones. We are not liable for pre-existing damage or for damage that is an unavoidable result of standard testing. Items must be collected within a reasonable time after the report is ready.

To the extent the law allows, our liability for any claim relating to a service is limited to the fee paid for that service.

The content, logo, report formats and course materials on this website belong to IIGL and may not be copied or reused without written permission.

Cancellations and refunds are covered on the Refunds & Cancellations page.

These terms are governed by the laws of India. Disputes are subject to the courts at Kolkata, West Bengal.

We may update these terms; the version on this page is the one that applies.
