"As people have personality, gemstones do too. Their appearance is function of many factors such as color, size, cutting, clarity, lighting conditions and influenced by the surrounding jewel if mounted. Their inclusions are of special interest for the gemologist, revealing much about them, and, by the landscapes drawn, take the observer in a voyage into another world."

GFCO GEM LAB is the brand name of Geafinco SA for its gemological laboratories services; gemstones are guaranteed to have been examined by qualified gemologists.

Besides the classic gem identification report, we have also developed the "Master Report" which includes a detailed quality grading. Explanation features on the report itself and extensively in the Explanatory Section of this website.
