The founder and managing partner of THE NATURAL GEM has been active in international gemstone trading for 30 years. As a doctor of economics and a certified gemmologist in Switzerland, Germany and the USA, among other countries, he is one of Europe’s leading experts on naturally-coloured, untreated gemstones and investments in them.

His bestseller, “INVESTMENTS IN GEMSTONES”, which was first published in 2017, was the first book to provide profound insights into the world of valuable gemstones. It covers both the mineralogical and historical aspects of gemstones, explains what aspects are important and provides an overview of price development.
