Our Mandate

The State Diamond Trader is a state-owned entity established in terms of Section 14 of the Diamonds Act 56, 1986, as amended (“the Act”). It operates in the diamond industry with the aim to grow local diamond beneficiation.

The mandate of the State Diamond Trader is to buy and sell rough diamonds and to promote equitable access to and beneficiation of the country’s diamond resources. The entity strives to address distortions created by the country’s historical exclusion of certain population groups from economic participation.

The entity is empowered by law to purchase up to 10% of the run-of-mine (ROM) production from all diamond producers in South Africa. It sells to registered customers through an application and approval process.

The State Diamond Trader is a schedule 3B entity in terms of the Public Finance Management Act (PFMA), 1999, as amended.

Our Producers

Producer's Role

A diamond producer in South Africa means any person entitled to win or recover diamonds in terms of sections 19, 25 and 27 of the Mineral and Petroleum Resources Development Act (Act No. 28 of 2002). Stated simply it is any legal entity that lawfully mines diamonds in South Africa.

The Diamond Second Amendment Act, 2005 | (extracts) Section 59B (2)

At the end of every production cycle, a diamond producer shall offer all the unpolished diamonds produced by him or her in that production cycle to the State Diamond Trader and specify the fair market value of those diamonds. This is to enable the State Diamond Trader to inspect such diamonds for the purpose of selecting diamonds for purchase as contemplated in subsection (1).

Operational Plan

In addition, the State Diamond Trader requires that all diamond producers complete an Operational Plan which indicates the terms of business between the State Diamond Trader and the producer.
