值得了解
Gem-A is an education and membership body, not a report-issuing laboratory; no gem testing or report service appears on its official site, and the entries above are qualifications rather than reports. Its FGA and DGA register verifies individual members, not reports. A separate organisation in Athens named Gem Testing Laboratory appears on gem-a.com as an accredited teaching centre and is not a Gem-A laboratory.
