Adding Dignity to the Workbench — The Group Mars Way

In the sparkling world of jewellery, one visionary company chose to shine the spotlight on those who toil at the workbenches and are seldom in the forefront.

The Vyas brothers—Kamlesh, Rajesh, and Himanshu—Directors of Group Mars and Rams Jewels, have spent nearly four decades building not just a successful enterprise but a humane model of manufacturing that values artisans as much as the product itself. Thanks to them, a quiet transformation has been set in motion—turning an unorganised segment of the industry into one that places dignity, ethics, and empathy at its core.

Kamlesh Vyas sums up their work culture in a single line: “Our industry’s real gold lies in its people. When you build their future, you build your own.”

The best business practices followed by Group Mars led to the establishment of one-of-a-kind Karigar Park in Hosur, Tamil Nadu, in a joint venture collaboration with one of India’s leading retail chains.

The company has earned many awards, the most prestigious being the Zero Defect Zero Effect (ZED) Silver Certification, making it the only jewellery company to have received this honour! These remarkable achievements have drawn the attention of IIM Ahmedabad, which is now conducting a case study on the company’s people-first business model.

Solitaire International met with two of the brothers, Kamlesh and Rajesh Vyas, to find out what makes their companies stand out!

A commerce graduate with modest beginnings, Kamlesh Vyas started his career behind the counter at TBZ in Zaveri Bazar, Mumbai. The experience, though brief, shaped his understanding of how business and people connect. In the mid-1980s, the brothers—Kamlesh, Rajesh, and Himanshu—started a small jewellery manufacturing unit with just 20 karigars and a few machines in Mumbai.

Their goal was simple: to build a business where artisans were treated with respect. At a time when most workshops were poorly ventilated and workers slept beside their benches, the Vyas brothers ensured that every artisan who joined them was given good food, a clean working environment, and decent accommodation. “If you solve the basics—roti, kapda, makaan—for your people, they will take care of everything else,” Kamlesh Vyas states. That early decision became the foundation of the company’s philosophy.

Rajesh Vyas adds, “We are trying to glorify the lesser-seen side of the glorious industry.”

Over the years, they grew quietly but steadily. The firm’s insistence on doing things differently attracted attention—not just for the quality of the plain gold jewellery but for the integrity of their operations.

In 2003, after nearly four years of consistent outreach and discussions, the jewellery major headquartered in Bengaluru approached them with a challenge that others had failed to meet: to build a dedicated, world-class Karigar Park in Hosur, Tamil Nadu.

The Vyas brothers took it up without hesitation, moving more than a hundred artisans from Mumbai to Hosur, bridging not only linguistic and cultural divides but also the mindset gap between traditional workshop culture and corporate discipline.

That partnership has today evolved into a one-of-its-kind joint venture. The Karigar Park is a model for responsible jewellery manufacturing in India.

Setting High Standards

The facility is unlike anything the industry has seen—it’s a model like no other. Air-conditioned workstations, ergonomic benches, clean accommodation in a hostel, a canteen serving four wholesome meals a day, and ₹2 lakh medical insurance for every employee have replaced the dim, cluttered workshops that often continue to dominate the trade.

The Hosur unit alone houses 125 artisans, while the Mumbai unit, under the leadership of Himanshu Vyas, employs over 125 artisans and other supporting staff with ultra-high facilities for shop-floor designs aimed at ultimate luxury.

The Vyas brothers believe that each minute of a karigar is valuable and must be utilised for higher productivity within the limited time period. Group Mars operates with a professionalism rarely seen in jewellery manufacturing. The company practices Lean Management, Six Sigma, and the Theory of Constraints, borrowing best practices from the automotive and electronics industries. Its commitment to sustainability and quality earned it the Government of India’s Zero Defect Zero Effect (ZED) Silver Certification*—making the group the first jewellery manufacturer in the country to achieve that distinction.

The company has also received multiple MSME awards and is recognised by the Responsible Sourcing Council.

These achievements are a result of constant learning and adapting. Kamlesh has always believed that perfection is a moving target. “I follow sportsmen who keep breaking their own records,” he says. “Perfection can always be improved.” This spirit drives him to innovate continually—not just in manufacturing but in mindset. He encourages artisans to see themselves as professionals, not labourers.

The workstations at Rams Jewels, Mumbai, resemble modern BPO offices, complete with clean lighting, order, and efficiency. “My karigars don’t sit on the floor; they sit with pride,” he says.

Humane at Core
Professionalism aside, the Vyas brothers follow their 4P philosophy: People, Process, Planet, and Product. “People come first, always. Once they are secure and motivated, the rest—processes, compliance, and profits—follow naturally,” comments Rajesh.

It is customary to celebrate the birthdays of all karigars, including Bengali festivals at Group Mars. Other perks include free schooling for karigars’ children up to Class 10, and educational support beyond that, subject to merit. Kamlesh shares proudly that one of their karigar’s daughters recently earned admission to AIIMS Rishikesh to study medicine, and two other karigar’s children are pursuing engineering.

The brothers also make it a point to visit the hometowns of their karigars to check if there is an improvement in their standard of living and whether they are putting their hard-earned money to good use. They also attend family weddings or housewarming ceremonies to make karigars feel included and part of the company.

Doesn’t that involve a lot of additional cost? It does, asserts Kamlesh, adding, “If I had kept all the profits to myself, I might have added a few more crores to the balance sheet. But what we have instead is something no money can buy—a team that works with pride and loyalty.”

Attrition at both Rams Jewels and Group Mars is almost zero, and productivity levels are among the highest in the industry. “In fact, we even have the younger generation wanting to join the company,” beams Kamlesh with pride.

He reminisces about the pandemic times, when chaos swept the nation and migrant workers fled cities in fear, but he refused to let his people face that uncertainty. He fed all 250 employees throughout the lockdowns, ensured medical safety, distributed vitamins and other essentials, and maintained strict hygiene protocols. Of all the employees, only two tested positive for Covid, and they recovered fully in no time.

Carrying the legacy forward
The next generation of the Vyas family is already shaping the company’s future. The four children—Mihir, Ayushi, Rahul, and Siddharth (forming the acronym MARS)—are expanding the group into new ventures while keeping the same values at heart. Their brands—Raya, Zyga, and Shaar—aim to take the family legacy into retail and exports, blending modern design sensibilities with responsible craftsmanship. The family is preparing to launch its own collections that reflect both tradition and innovation.

Kamlesh is candid about the realities of the industry. He acknowledges that nearly 95% of India’s jewellery sector still functions in the unorganised segment. But he believes the tide can turn if more entrepreneurs commit to formalising their operations and dignifying their workforce.
From the early days of working with 20 artisans to now managing hundreds across two states, the brothers’ mission has remained unchanged: to create an ecosystem where artisans thrive, not merely survive. For them, success is not measured by tonnes of gold produced but by the lives transformed along the way.

Kamlesh & Rajesh Vyas conclude that they want to be the disruptors, they want to be the change, and compete with global brands. “We want to take India’s handcrafted jewellery to the world. We want to redefine gold jewellery manufacturing,” they state.

In fulfilling the dreams of the karigars, the Vyas brothers have fulfilled their own. The journey is more than a success story—it is a call to conscience for an industry that often forgets the human hands behind its brilliance. By turning empathy into enterprise, they have given Indian jewellery manufacturing what it has long needed: a heart.
