CV of Alexander Streeb

Alexander Streeb (born 1960) is the founder and managing director of the German Gemstone House.

Mr. Streeb is a renowned financial expert and has worked in the financial services industry for 35 years. He is co-founder of the asset management company German Capital Management AG, which, with assets under management of around EUR 300 million, is one of the most successful asset management companies in Germany. In the spring of 2018, after more than 20 years on the board and supervisory board, he left the company to concentrate fully on the German Gemstone House. In addition to his technical competence in all aspects of finance, his expertise lies in the areas of corporate development, sales and communication.

He turned his passion for colored gemstones into a career in order to bring national and international investors closer to the forgotten, centuries-old asset class “colored gemstones” by making them easy, understandable and transparent to invest in. To do this, he brought together international experts with their deep, well-founded special knowledge in a team and created a quality-assured system for the purchase of investment colored gemstones.
