About us

Solomon Katzman, Antwerp
Solomon Katzman is privately owned company and working with import/export diamonds in Antwerp.
Continuity and sustainability in its decisions are typical advantages of a sole proprietor enterprise since it can successfully side-step what frequently are short-term objectives and interests of public limited companies. Hectic “actionism” driven by quarterly figures certainly is not typical for Solomon Katzman. We in our culture thinks and acts in generations and not in quarters.
A strict reinvestment policy ensures that the earnings generated remain in the Company. This reinforces the level of reserves, provides the company with a high equity ratio and thus secures its independence. This means that its sovereignty in terms of decision-making is preserved, and the Company can develop sustainably on its own without having to rely on others. In the past decades, the family Katzman has delivered compelling evidence that this is the correct approach to follow.


The strong relationships with our extensive network of suppliers built on trust and every step of the way we adhere to the highest ethical standards, where our diamonds come from and how we do business with our suppliers and our clients.
Our solid time-tested relationships with the mining companies and wholesalers ensure that we get exactly the right stone that you want and at the right price.
By virtue of our global presence and multicultural identity, our highly skilled and knowledgeable team makes it possible to give an outstanding customized service to our clients.
We carefully sort and rigorously inspect every rough diamond as part of our unforgiving quality control scheme in Antwerp
The rough diamonds that we work with are all conflict-free and ethically sourced from trustworthy partners mainly in Sierra Leone, Guinea Conakry, Namibia and South Africa
