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.

Oliver Kleimaier (born 1979) is, alongside Mr. Streeb, the managing director of the German Gemstone House and has a wide range of professional experience.

Originally a trained banker (IHK), he continuously expanded his financial knowledge in various positions in national and international sectors of the private sector with specialist knowledge of logistics, organization, planning and strategy. In 2021 he joined the German Gemstone House, initially as head of administration, before being appointed to the management board in 2022.

Day in and day out, he is able to let his passion for the finer things in life flow in together with his specialist knowledge in the German Gemstone House for the customers and employees of the house.

His commitment to effective processes, customer-oriented solutions and financial stability continually contributes to the company’s success.
