Certification by independent gemological laboratories plays a key role in the international gemstone trade, providing assurance to both buyers and sellers. As a dealer, we want to ensure that all the gems we sell are exactly as described. 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 all gemologists know that gemstone identification by appearance is impossible. Gemological testing requires special equipment that most jewelers simply do not have.
For the above reasons we offer certification options from well-respected gemological laboratories.
You will find that many of our gems, especially the more valuable gemstones, have certificates included when we offer them for sale. You can view these certificates online when you visit the detail pages for the relevant gems.
We are glad to obtain a laboratory certificate for any gemstone in our collection which has not already been certified. Below is the current fees for certification from various labs in Bangkok. Please contact us if you would like to obtain a certification for any gemstone you are purchasing.
