Natural Unheated Sapphire 4.02 carats
A beautiful natural unheated sapphire with violet blue changing to purple color and completely transparent. I bought this sapphire in Bangkok while in a trip with my friend Terry, I was not sure that the sapphire would be really unheated as I had many experiences in Thailand where the stone even had a certificate from the TGI (Thai Gemological Institute) and when the GIA did they testing it came as heated. Fortunately this one Khong (the seller) was correct.
