The short documentary, directed by GRS CEO and chief gemologist Dr. A. Peretti, along with GRS gemologists Willy Bieri, Lawrence Hahn, and Matthias Alessandri, explores the rough gem, predicts its size, and conducts color grading and UV-fluorescence testing. Surprisingly, it exhibits a striking similarity to the finest Burmese rubies, with a captivating pigeon's blood color and strong fluorescence.
