Martin Steinbach

Martin Steinbach: As a teenager, I sought crystals in mines and old pits. In the early 1980s, I left university and opted to explore real life, traveling around the world. In 1983, while in Bangkok, I became captivated by the passion for cut and rough gems. I completed my education at AIGS, the Asian Institute of Gemological Sciences.

Upon returning to Germany, in Idar-Oberstein, one of the oldest gem cities globally, I earned degrees as a graduate gemmologist from the German Gemmological Society and as a diamond expert.
In 1984, I founded my own gem trading and gemological consulting company. After over 30 years of dedicated work, my first book, “Asterism-Gems with a Star,” was published in 2016. With 900 pages and weighing over 4 kgs, it is already hailed as a “classic,” covering every conceivable aspect of gems with a star.
In 2023, my second book, “Star Gems-A Fascinating World,” was published in American English. Presented in a modern square format with 440 pages and featuring around 700 pictures, graphs, etc. Importantly, this compendium includes full gemological data for each gem, about 300 references for further studies, and over 1000 keywords.
