To check your diamond, you can bring your diamond to our laboratory so we can examine it and take your diamond on the same day. Test results will be in the form of memo or certificate.

The content of certificate is presented in greater detail and each certificate is ALWAYS accompanied by a photograph of the stone. For memos and certificates sample can be viewed in our website www.agl-igp.com.

To check your emerald, it will be better if you bring your emerald in the condition apart or loose from its mounting thus we can examine it accurately.

If the emerald is tightly closed or we found any suspicion, we will ask to be removed from its mounting. If there is no suspicion, then it can be examined without removing it from its mounting.

For diamond: If you want to certificate your diamond, it should be in form of loose stone. But if it’s not, the certificate with a photo or memo still can be made.
For colorstones: types of colorstones such as Ruby, Sapphire should be in form of loose stone for the accuracy of detecting a specific treatment and synthetic as well.

You can bring it to our laboratory for the examination or certification, because there are many gemstone species that are red such as red ruby / ruby, spinel, garnet, tourmaline, etc.

You can check in our website: www.agl-igp.com and then click report check. Enter the certificate’s code or memo and insert the weight also. If there is your gem’s certificate or memo in our website, to ensure the gem and the certificate is still the same, the gem must be brought back to us for the re-check process.

In certification process we use international standards and refer to the international provisions and AGL is an independent laboratory that only provides certification service without any trade factor. Some lab abroad that uses international standards usually accepts results of our lab where each test result using English language. And we also examine the gems using advance instrument with the most recent technology.

Because it depend on the difficulty level of examination, queuing condition, not only customer but also instrument queuing. And for the gem that are still on its mounting (either on rings, earrings, etc) sometimes it takes time to remove it from its mounting. Above all, our examination emphasized on accuracy and precision.

Sorry, but we can’t. We only help you to remove the gem from its mounting but we can’t replace it back. It will be better if you bring the gem in the form of loose stone before we examine it.

We are open from Monday to Friday at 10.00am to 03.00 pm

Sorry, we can’t. The gems have to be taken back on the same day. We can’t keep any customer/your gemstone in any circumstances.
