"Analysis by the AGTA's gem testing center concluded that the deep green garnets from Soghan were andradite, and that the chromatophores were Fe3+ and Cr3+, thus putting them in the "demantoid" category. I talked directly with the AGTA lab a few years ago. The analysis was also presented at the 2006 World Gemological Research Conference. An abstract of the presentation can be found in Gems & Gemology, Fall 2006, page 131." (Ed Rosenzweig info)
