The stone is GFCO certified as heated with minor residues and I have received a photo of the certificate. I know what minor residues mean and I'm okay with it. I'm wondering if it makes sense to have the stone certified a second time by either AIGS or Lotus. I also have no idea which of these two to choose.
Yes, because the value is very different if it’s moderate residues. There is also GIA and GRS in Thailand. Both are better recognised than AIGS or Lotus.
