Centrally located in the heart of the restricted area of the Antwerp diamond district, our office is compliant with the most stringent security measures and the latest insurance requirements, and has several safes for diamond storage in addition to the vault in the basement of the building.

Premises offer eight modern and comfortable air-conditioned viewing rooms with sorting benches facing northern light for optimal diamond inspection. Each room is equipped with security cameras, telephone, high-speed wifi internet access, and all the necessary tools for diamond viewing. The office also has a dedicated separate administrative support area and a boardroom with video-conference facility.

Our diamond sales are usually conducted in Antwerp. However, depending on the seller's requirements, Bonas is capable of organising similar events in other trading centres, such as Dubai or Gaborone for instance.
