NEED TO KNOW
Frequently asked
questions.
Have a question that isn’t covered here? Contact the lab and tell us what you need tested.
Ask our team →Why should I get a gemstone tested?+
Testing can help you understand a stone’s identity and certain characteristics before buying, selling or keeping it.
What should I bring to the lab?+
Bring the gemstone or jewellery item and any existing report or purchase documentation. Contact the lab first if you need special handling guidance.
Can I verify a report online?+
Use the report verification form above once the lab’s certificate database has been connected. Always match the result to your document and physical item.
Does a grading report confirm market price?+
No. A gemological report describes examination findings. Market value depends on additional factors and is not guaranteed by a laboratory report.
How long does testing take?
Turnaround depends on the item, requested service and current workload. Contact the lab for an estimate before submitting your item.
