Introduction

Dimexon is a world-leading diamond manufacturer, founded in 1966 by Pankaj Mehta, and has been a De Beers Sightholder since 1976.

The family-owned company has offices around the world including in Antwerp, Dubai, Mumbai and Hong Kong.

As a fully integrated manufacturer, Dimexon is dedicated to leading the way in entirely traceable, responsibly sourced and ethically produced diamonds. It works closely with trusted mining partners to buy rough diamonds from proven sources. All cutting and polishing takes place at Dimexon’s facility in Coimbatore, which has a workforce that is more than 80% female.

The company’s dedication to technical excellence as well as strong ESG principles has made it the preferred loose diamonds supplier for many of the world’s most famous luxury houses. All Dimexon diamonds – including melee – are tracked through the supply chain using bespoke cloud-based technology hosted by SAP. Reporting is made available to clients on stones’ origins.

Dimexon offers a 100% natural diamond guarantee. Diamonds are tested at multiple points throughout the supply chain to ensure zero contamination of lab grown diamonds.

Corporate Social Responsibility

Dimexon is a fully audited member of the Responsible Jewellery Council, a signatory to the Watch & Jewellery Initiative 2030, UN Women’s Empowerment Principles, and a member of the World Diamond Council.

The manufacturer is an ESG leader within the industry, often raising the bar with voluntary standards. Dimexon is fully Anti Money Laundering (AML) compliant, and in 2005 it became the first diamond company in the world to be a voluntary signatory of the International Financial Reporting Standards (IFRS). In 2017, it began providing clients with traceability data and reporting, and then in 2023 it signed up to the Science Based Targets Initiative (SBTi) and achieved Zero Waste to Landfill (ZWL) certification in 2024.

Dimexon produces a publicly available ESG report annually that documents all its environmental, social and governance activities, as well as setting out targets for the future.
