Richard T. Liddicoat, known around the world as the Father of Modern Gemology – and affectionately as “RTL” – created the GIA International Diamond Grading System, expanded GIA’s education programs, elevated its laboratory and research functions, developed gem identification instruments, and wrote gound-breaking articles and books on gems. But common to all his accomplishments was his eagerness to share knowledge with others. He was warm, caring, and concerned. He loved new ideas and innovation and encouraged these with everyone he met.
RTL would have celebrated his 92nd birthday on March 2. This blog was created for all of us who knew him and learned from him. Let’s share our fond memories of this most unforgettable man.
