EducationMineral lab. in United States

8th Apr 2017 13:31 UTCHerby Lam

I used to deal with gem stones, and GIA was the lab I sent for authentication and certification, I have a mineral carving specimen, can anyone tell me where I can send in USA for authentication and certification? I mainly want to find out if the color of the piece is natural, and issue me a lab. report. Thank you.

I'm thinking someone at GIA could point you in the right direction, since you have seemed to work with them in the past......
