When Vaibhav Karnavat talks about diamonds, he does not speak the language of vaults, inheritance, or guarded occasions. He speaks instead about movement, memory, and everyday life. The founder and CEO of House of Quadri comes from a family with a long-standing association with the jewellery business. His father, Narendra Karnavat, was among the pioneers who introduced technologically advanced machine-set manufacturing techniques in the Indian jewellery industry and partnered with the well-known Jewelex group. Vaibhav himself spent more than eight years leading the manufacturing division that created gold and platinum diamond-studded jewellery before eventually launching House of Quadri in November 2021 from Mumbai.

The idea for the brand emerged from a contradiction he could no longer ignore. “I spent years watching expensive diamond pieces sit in lockers,” Karnavat says. “Made with so much care, worn almost never.” He had seen the craftsmanship, the labour, and the emotional bond that went into these pieces, only for them to disappear into safes and emerge for weddings or special occasions. Around 2020, as lab-grown diamond technology evolved rapidly and became virtually indistinguishable from mined diamonds, Karnavat began paying close attention to how the market abroad, especially in the United States, was reacting. He realised India would eventually follow. “This was the moment to build something that closed the gap between the jewellery people owned and the life they were actually living,” he says.

That philosophy sits at the centre of House of Quadri. The company was born from the belief that diamond jewellery should not feel intimidating, inaccessible, or excessively precious. Instead, it should feel modern, wearable, meaningful, and natural to everyday life. Even the brand name reflects this thinking. “Quadri,” derived from Italian, refers to diamonds in the suit of cards while also evoking the four corners of a quadrilateral, suggesting stability, strength, and timelessness.

Karnavat often describes the brand’s guiding philosophy with a simple phrase: “Follow the Feeling.” In practice, that philosophy shapes everything from design to customer experience. “Every piece goes through a process of asking whether it feels right on the body, in motion, in real light,” he explains. The idea is not to create jewellery that waits for permission to be worn. Instead, the customer House of Quadri imagines is already living a life worth adorning. The jewellery is simply meant to become part of that rhythm. “We’re not here to occasion-gate jewellery,” he says. “We want it to feel as natural as putting on your favourite thing in the morning.”

That attention to lived experience is visible in the details the company obsesses over. Karnavat believes certification alone cannot define a jewellery brand anymore. “Certification is the floor, not the differentiator,” he says. What matters to him are the details customers may feel before they consciously notice them: the way a chain falls against the skin, the balance of a ring, the finesse of the prongs, or how comfortable a pair of earrings remains at the end of a long day. Because the design and manufacturing operations are based in Mumbai, House of Quadri maintains unusually close control over every stage of production instead of outsourcing much of the process.

The company positions this approach as “The Quadri Experience,” though Karnavat insists it is not merely an added layer of service. For him, it is inseparable from the product itself. Customers return years later for resizing, re-polishing, or redesigning, and he sees those interactions as part of a longer relationship rather than post-purchase service. “That’s the relationship we’re in,” he says.

At the heart of House of Quadri is the idea of ethical luxury. Every piece is crafted using lab-grown diamonds alongside responsibly sourced gold, while the company also incorporates recycled gold wherever possible and attempts to minimise material waste during production. The brand stresses transparency in sourcing and certification, with all solitaire diamonds being IGI-certified and carefully chosen for brilliance and precision-cutting to maximise light retention. The company’s larger argument is that luxury no longer needs to come attached to environmental or ethical compromise.

Karnavat is careful, however, not to frame the rise of lab-grown diamonds as a hostile rejection of natural diamonds. Instead, he sees it as a shift in consumer thinking. “We don’t enter that argument,” he says. “We reframe it.” He points out that lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. “That’s not a claim, that’s chemistry,” he adds. What has changed, according to him, is the set of questions consumers are now asking. Younger buyers want to know where something came from, what impact it had on the world, and whether it aligns with the life they want to live. “We have honest answers to all three,” he says. For customers who remain unconvinced, House of Quadri prefers demonstration over persuasion. Karnavat says the company does not aggressively push comparisons between mined and lab-grown stones. “Put a HOQ piece next to anything else,” he says. “Let the feeling do the convincing.”

Design remains central to how the brand tells its story. House of Quadri views diamonds as markers of personal journeys rather than merely symbols of wealth. The collections move between timeless solitaire engagement rings, everyday studs, statement bracelets, and bespoke creations designed in collaboration with clients. The aesthetic leans toward minimalism while still allowing room for expressive, contemporary design. The company’s customers — professionals, entrepreneurs, creatives, and self-driven individuals generally between the ages of 25 and 50 — are seen not simply as buyers of jewellery but as people investing in memories and self-expression.

Technology, too, plays a large role in the company’s operations. From 3D CAD modelling used to ensure design precision to virtual consultations and digital catalogues that simplify the buying journey, House of Quadri blends traditional craftsmanship with a digitally enabled customer experience. Customisation forms a major part of this approach, allowing clients to co-create pieces that reflect their own stories and preferences.

Today, House of Quadri operates a flagship boutique in Mumbai at Kitab Mahal in Fort, spread across 2,000 square feet, while also maintaining a presence across Delhi, Gurgaon, Hyderabad, and Bangalore alongside its online platform. Karnavat describes the company’s expansion strategy as deliberate rather than aggressive. “Every new city is a conversation, not a rollout,” he says. The focus, he insists, is not on competing in a race to the bottom on price but on building emotional loyalty. “The brands that last are the ones that build a point of view,” he says. For House of Quadri, that point of view is clear: jewellery should be worn, lived in, and remembered, not locked away waiting for permission to shine. “Like a beautiful piece of art, your diamonds should be treasured, celebrated, and styled every single day,” Karnavat says. “With this new age diamond, we want to empower every woman who can choose luxury as a habit and make every day a diamond worthy.”
