Family-owned, medium-sized, friendly - KOOS Edelmetalle.

Gold and precious metals are the very embodiment of stable value. Their stability and solidity are valued more today than ever.

Established in 1980, KOOS has gained reputation in the industry for its professionalism, reliability and uncompromising quality over decades. Located in Renningen, Germany, between Pforzheim and Stuttgart, the region strongly represents its middle class values and virtues of reliability, straightforwardness, diligence and precision.

Virtues that are literally worth their weight in gold, and form the basis of our long-lasting partnerships with our customers. As a family-owned company, we maintain direct, personal contact with our business partners. As a medium-sized company, we know what is important to our customers. And as a family company with lean structures and flat hierarchies, we are able to react quickly and easily to the wishes of our customers.
