For well over a century, Hennig's primary role has been to help our clients procure rough diamonds.

 

In the late 1930's and early 1940's, Hennig was instrumental in developing the diamond industry in the soon to be established State of Israel. Hennig helped the local industry to obtain the first direct supply of rough diamonds from the CSO (Central Selling Organisation), the forerunner of the Diamond Trading Company (DTC) Confident that the industry was likely to grow, Hennig became the first broker (in 1963) to appoint its own representative in Israel.

During the post war years, Antwerp emerged as the major European diamond-trading centre and most of the leading Antwerp names have dealt with Hennig in one way or another.

 

Likewise, the diamond industry in the USA expanded, thanks largely to the wartime influx of dealers and manufacturers from Europe. Many in the American trade continue to look to Hennig for their broking services.

Israel, Antwerp and the USA were not the only markets to develop after the Second World War. By the late 1940s, India, the country with the oldest diamond tradition of all was re-emerging as a manufacturing centre.

Aided by the lifting, in the 1960s, of the Indian government's embargo on diamond imports, India began to establish itself as the largest cutting centre, in terms of workforce, in the world. By advising the Indian industry on improvements to its manufacturing skills and the development of sales outlets as well as presenting their merits to the CSO, Hennig played a similar role in India as it had previously done in Israel. As with the other centres, most of the important names in the Indian industry have also been associated with Hennig.

In addition to playing an important role in the development of the diamond industry, Hennig played an active role in handling the purchase of several famous diamonds. Amongst others, the 726-carat Jonker Diamond in 1935, and the 968.9-carat Star of Sierra Leone in the 1970's, both purchased by Harry Winston.

Hennig aims to successfully manage all aspects of the relationship between our clients and the DTC.  We work to ensure that clients fulfil all DTC criteria, are equipped with the most up-to-date market information and are fully aligned with current industry trends. 

Our offices in London, Antwerp, Tel Aviv, Mumbai, New York, Bangkok, Johannesburg and Gaborone, ensure clients have the best possible presence and representation in all the major diamond centres. This global reach, linked with state-of-the-art information technology, affords our client’s real-time market information, historical data, and analytical tools required to make informed business decisions.

Anticipating changes to the industry, we have continued to expand our diamond and diamond jewellery services, Hennig is now a partner in Worldwide Diamond Manufacturing (WDM), a hi-tech manufacturing facility in Visakhapatnam, India This facility allows us to offer contract manufacturing for rough polishing that would otherwise be uneconomical to produce in local centres.

With the fluctuating nature of the diamond and fine jewelry markets, Hennig also recognized the need to offer strategic advisory services that utilize an analytical approach and advanced quantitative tools, to compliment its broking offering. After launching these services in 2004, Hennig later transitioned them under the Isidor banner in 2007.

At Hennig, we continue to add to our portfolio of services, thus ensuring a pivotal role in the diamond industry of the future.
