Latest Gems in the Store:

Before you purchase a gemstone in our online store you may want to have it certified. 

There is no laboratory in Pailin so we will send the gem(s) to Chanthaburi, Thailand, and have it analysed and certified in a GIA graduated Laboratory. 

The laboratory we use is: 


The Chanthaburi Gemological Laboratory Co. Ltd. (GLC) is an independent gems laboratory in Chanthaburi, Thailand. Graduated gemologists from Gemological Institute of America (GIA), Asian Institute of Gemological Science (AIGS) and the faculty of gems, Burapha University. 

19/4 Srichan Road, Watmai,A.Muang,

Chanthaburi 22000 Thailand.

As we have to bring the gemstone(s) across the border to Chanthaburi (100 Kilometres away) the cost of certification is: 

($20) + ($15 per gem for Identification Report/ $25 for Enhancement Report)

 Identification Report: The laboratory will certify what kind of stone it is, if it is natural or synthetic, and whether there are foreign elements such as lead glass. 

Enhancement Report (Ruby and Sapphire only): Identification Report + reports of other color enhancement such as radiation, Beryllium etc...

Please contact us and we will identify the gems to analyse and evaluate your request.

We can perform the certification before you purchase a gemstone from us and you can change your mind and decide to not purchase the stone, even if you have paid for it, but the certification has to be paid upfront and is not refundable. 

The whole certification process will require up to 3 open days. 

You will then receive credentials to make direct confirmation online (HERE) with GLC, and an official sealed certificate will be issued for each gem.
