About Dimexon

Our integrity as a family-run company rests on our commitment to our staff, our fair and open dealings with our clients and mining partners and our longterm investment in the communities in which we operate.


Dimexon owes its existence to the vision of Pankaj Mehta, a self-made man who in 1966 founded what was to become an international market leader.

As a young man, he was determined to create a company that would stand the test of time, based on the values of integrity, transparency, attention to detail and support for the communities it works in. It was his vision and hard work that built up the company and set up the foundations for its success and sustainability
From his successful family background in jewellery retail in Coimbatore, Pankaj Mehta ventured to Mumbai aged only 16 with the ambition of founding a global diamond manufacturing business.

Under his astute leadership, Dimexon became a De Beers Sightholder in 1976, recognised for its adoption of the latest manufacturing systems and processes and its commitment to good governance.


Dimexon is now a second-generation family business professionally managed by the next generation of the Mehta family, namely Pankaj’s sons, Rajiv and Vishal Mehta.

In 2003, Pankaj Mehta challenged them to come up with a plan for the future. It was the starting point for the succession process in Dimexon. Corporate governance at the time was a rare term, so they started the process piece by piece. Rajiv and Vishal Mehta have always kept the vision of their father in mind. He aimed to create a sustainable and perpetual company with long-lasting value and longevity. For this reason, they have continued to improve their governance practices over the years. They embarked upon the transformation process – on the corporate structure and holding company side and the process side, establishing information systems. Rajiv and Vishal Mehta have shown that they have the passion, drive, and ability to take on the challenge of running a successful and sustainable business.

Female empowerment

When Pankaj Mehta decided to set-up his manufacturing plant in Coimbatore over five decades ago, he had a palpable desire to break down barriers. He championed local communities and hired local talent – primarily women. Three quarters of our staff are women, the largest proportion in the industry. We believe, it is our duty as a modern, diverse and forward-thinking business to support women’s rights and dignity in the workplace, creating a fairer and more productive business structure.

Equality, fairness and female empowerment are core elements of the Dimexon DNA. 
Technical training and flexible working hours help us retain and promote our female staff from Asia to Antwerp, working as account managers, in finance, servicing, sales and manufacturing. 
Building strong partnerships with respected mining companies who share our values allows us to strengthen our commitment to ethical working practices and the full traceability of our diamonds.


Our corporate responsibility is deeply embedded within our business philosophy. We have been a De Beers Global Sightholder since 1976, going above and beyond its strict rules on ethics, financial prudence and adherence to the Kimberley Process.

We are also a Rio Tinto Select Diamantaire and The Responsible Jewellery Council.

We are fully AML-compliant and have been a voluntary signatory to the IFRS since 2006. As the first diamond company to subscribe to IFRS standards, Dimexon led the way. In due course, De Beers required all its Sightholders to follow suit to improve financial transparency and the stability of the diamond sector.

We use our standing and reputation not just to benefit our own company, but to inspire organisations in the diamond industry to follow our example.
