Social and corporate responsibility

Corporate Governance
We recognize the importance of good governance for our business. To realize this fundamental goal, we aim to increase management efficiency and transparency by strengthening corporate governance and improving our internal control system. 
Conflict Diamond? 

Conflict diamonds are rough, uncut diamonds used by rebel movements or their allies to finance armed conflict aimed at undermining legitimate governments. In 1998, the Non-government Organisation (NGO) Global Witness brought to the world’s attention the fact that rebel groups were funding their war against the legitimate government in this way.

ZDT is working with governments in Africa and beyond through the United Nations and other international organizations to ensure we do not broker diamond deals that fund conflicts.

At ZDT, we can guarantee with 100% confidence that all of Zimbabwe  diamonds are conflict-free there is no war in Zimbabwe nor any other form of fighting that can be described or defined as fighting or conflict.

ZDT Diamond Policy

Every diamond deal we broker is conflict-free and child labour free.

ZDT is aware of the problem of conflict diamonds and has taken measures to guarantee that no conflict diamonds enter brokrage system.

 Kimberly Process

The Kimberley Process Certification Scheme18 started when Southern African diamond-producing countries met in Kimberley, South Africa, in May 2000, to discuss ways to stop the trade in ‘conflict diamonds’ and ensure that diamond purchases were not funding wars against legitimate governments rebel movements
Zimbabwe is part of Southern Africa with a very peaceful population and a strong transitional government that is working towards a free democracy. ZDT supports Zimbabwe and its past, present and future ability to administer a country free from conflicts.


In the future we hope to create a structure such as DEF we are currently finding local charities in Zimbabwe to endorse.

Founded in 2007, The Diamond Empowerment Fund™ (D.E.F.) is a non-profit international organization with the mission to raise money to support education initiatives that develop and empower economically disadvantaged people in African nations where diamonds are a natural resource.
