Gems and Jewelry Companies: A Diamond Legacy Rooted in Ethics

In a world where luxury often comes under scrutiny, Indian-based natural diamond manufacturer Dimexon has steadily built a reputation for integrity and sustainability that few rivals can match. Founded in 1966 by Pankaj Mehta in Coimbatore, the company emerged as an ethical pioneer long before ESG became a buzzword in boardrooms. Over the decades, Dimexon has become an emblem of responsible luxury, placing women’s empowerment, transparency, and traceability at the heart of its operations.

This Gems and Jewelry Companies news report highlights how Dimexon has gone from a quiet leader in ethical sourcing to a trailblazer in aligning its practices with global environmental and social standards. From reducing carbon emissions to empowering a female-majority workforce, the family-run firm is showing the industry what sustainable luxury truly looks like.

Solar Power and Global Standards

Dimexon’s Coimbatore facility now runs on 75% solar energy, slashing 942 metric tons of CO2 emissions in just eight months. The milestone was documented in the latest stakeholder report of the Watch & Jewellery Initiative (WJI) 2030, of which Dimexon is an active member. But the company’s achievements go far beyond clean energy.

All diamonds produced by Dimexon are fully traceable, backed by a digital ERP system from SAP. The firm strictly adheres to global compliance frameworks such as the Kimberley Process and the World Diamond Council’s System of Warranties, while also mandating its suppliers to meet stringent responsible sourcing criteria. With offices in Paris, Antwerp, Hong Kong, Mumbai, and Dubai, the company embeds ESG principles into every aspect of its operations.

“We believe growth must be not just profitable but sustainable,” says Morgane Winterholer, Dimexon’s Paris-based chief growth officer. Her cross-functional role blends communications, client relationships, and ESG oversight — a reflection of how deeply sustainability is integrated into the company’s DNA.

Staying Ahead of Regulations

Dimexon is proactively embracing the EU’s Corporate Sustainability Reporting Directive (CSRD), even though the privately held company isn’t yet required to. “We decided to treat it as a tool for evolution,” says Winterholer. “Some of our clients need to comply, others don’t. But we have to be prepared across the board because we operate in a global supply chain.”

This mindset isn’t new. In 2005, Dimexon became the first diamond company to voluntarily adopt the International Financial Reporting Standards (IFRS). By 2017, it was openly sharing traceability data with clients. In 2022, it launched its first ESG report and joined the WJI 2030 platform.

A Stronghold for Women in the Diamond Industry

One of the most compelling chapters of Dimexon’s story began in the 1970s, when founder Pankaj Mehta took the then-unusual step of hiring women to work in diamond manufacturing — a male-dominated industry. Today, 76% of the company’s workforce are women, including India’s head of manufacturing.

Dimexon signed the UN Women’s Empowerment Principles in 2023 and reports a 91% return-to-work rate after maternity leave — a remarkable figure in the regions where it operates. “We understand that careers aren’t linear,” notes Winterholer, “and our support structures reflect that.”

Brothers Rajiv and Vishal Mehta, who took over management in 2008, continue their father’s legacy while steering the company toward new horizons. “When you’re part of a family business, you think long-term. That gives you the resilience to evolve,” says Winterholer.

Setting Benchmarks in Transparency

A De Beers sightholder since 1976, Dimexon has consistently surpassed industry requirements. The company’s ESG model is built around four foundational pillars: environmental synergy, product integrity, responsible business conduct, and social stewardship.

These principles are not just decorative—they are measurable. The firm has committed to key performance indicators and publishes annual ESG reports outlining its progress. The 2024 report confirmed “zero waste to landfill” status at its Coimbatore plant, a sharp drop in energy use, and enhanced monitoring of indirect emissions (Scope 3). The just-released 2025 report includes a new roadmap aligned with the needs of employees, clients, mining partners, and investors alike.

A Model for Resilient and Responsible Growth

As the diamond industry faces global economic headwinds and political uncertainty, Dimexon’s continued commitment to ESG stands out as a model of how quiet leadership can have a loud impact. In times of disruption, companies like Dimexon provide stability not just for their shareholders, but for communities, ecosystems, and the global supply chain.

The company’s foresight in adopting voluntary regulations, uplifting women, minimizing carbon footprints, and maintaining transparency is not just a business strategy — it’s a value system. The Mehta family has successfully fused tradition with innovation, ensuring the business not only survives but thrives in an era of conscious capitalism. In a sector often overshadowed by scrutiny, Dimexon is illuminating a path that others would do well to follow.
