Who I Am
I’m P.J. Joseph, a trained gemologist with over 40 years of experience in the fascinating world of gemstones, and a long-time trainer and writer. My journey blends scientific precision with storytelling, as I’ve spent decades educating others through training and writing. I hold a professional diploma (DgemG) in gemology from the Deutsche Gemmologische Gesellschaft e.V., Idar-Oberstein, Germany, and the Gemological Institute of India, Mumbai, India. Since 2006, I’ve written over 40,000 articles on Blogger —just one post after another, day after day. The result? Thousands of daily visits from readers around the world. All organic. All earned.
