GemSelect proudly provides gemstone certification for almost all of the gemstone varieties we offer.
Gemstone certification can be quite a hassle, not to mention very time consuming. Although most jewelers are experts when it comes to diamonds, when it comes to colored stones, many jewelers have very limited knowledge. Jewelers will often attempt to identify a colored gemstone based only on its appearance, but we all know that gemstone identification by appearance is impossible! It's like judging a book by its cover. Gemological testing requires special equipment that most jewelers simply do not have.
For the above reasons GemSelect offers certification from well-respected gemological laboratories.
Gemstone certification for items on our website is completely optional. If you would like certification, it can be requested from any one of our gemstone detail pages prior to checking out. We also offer complimentary company reports, which can be previewed before buying gemstones by clicking on "Certificate Options" above the "Add to Cart" button. Once the gemstone has been purchased, the complimentary gem report can be accessed via the customer account. To do this, simply login to your account, select "Order History" and then click on "show details". You will see an option below each listed item to "Download Identification Report". Simply click on this and print out your PDF report.
Please see below for our certification options and details.
Please Note: The certificate must be added before adding the item to your shopping cart and prior to checking out. Once your order has been processed, it will be too late to amend the order because the actual gemstone must taken to the lab for inspection in order to provide a certificate.
Gem Certification Laboratory Options
Gem certification and the pricing below is based on single gemstone testing only. Therefore if your order consists of a single order composed of two or more gemstones (such as a matching pair or lot), the lab will test only one specimen from the pair or lot.
We currently offer brief identification reports from your choice of two well-respected independent gemological laboratories:
Please Note: We are not able to provide identification tests on very small gemstones that measure 2 millimeters and under, since local labs do not have the advanced equipment required for such small items.
Types of Gem Certificate Offered
The certificates issued by both AIGS and BGL Gem Labs are:
The certificates can identify the gem type (natural or man-made) and they may also indicate whether or not the gemstone has been treated or enhanced (heated, fracture-filled, oiled, irradiated, etc). Please note that comments regarding treatments are usually only supplied for gems which if treated have a marked price difference, such as sapphire and ruby.
Note: Some treatments cannot be detected using standard equipment, such as beryllium diffusion, polymer stabilization or dyeing. These types of treatment may not be identified on the reports. Testing for uncommon treatments require special equipment which many laboratories do not have access to. Also, in many cases, testing for such treatments can only be confirmed by damaging the gemstone.

AIGS and BGL brief reports are ideal for those seeking assurance of authenticity and gemstone type. Reports from these labs can be obtained at minimal expense, which is why they are highly recommended. The gemologists are experts in their field, though they tend to be non-native English speakers.
Prices for services in Thailand are much more affordable than they are in other areas of Asia, Europe, America and Australia.
