Who we are
People, networks, responsibility.
Carat Investments is supported by a Swiss principal entity and a historical trading network — with clear responsibility and personal leadership.
Swiss principal entity
Retter Inc.
Retter Inc., headquartered in Switzerland, is the regulatory and operational home of Carat Investments. It carries responsibility for structure, compliance and client relations.

Fabian Lauterwasser
CEO
Trading heritage & network
Schupp Family Office
Active in the colored gemstone trade since 1744. The network to cutters, laboratories and mine operators, grown across generations, forms the substantive basis of our work.

Multi-family-office structure
Additional Family Offices
Two further family offices stand behind Carat Investments and prefer not to appear publicly. Together with the Schupp Family Office, they form a multi-family-office structure — a constellation that provides stability and safeguards entrepreneurial independence. In practice, this means we can align business decisions, pricing and mandate management consistently with the long-term interests of our clients — without compromise from short-term capital pressure.
